So you are pressing "Submit" with a non-blank comment, but the comment doesn't appear on your label, right? Or are you expecting the comment to render in realtime while you type?

Hey guys question. So if php is a meme what should I use? Or what other options do I have? Preferably free
What is /wdg/ official and approved stack?
>>55237263
Oh right, the problem is your first return: you always render the template and never get to the condition.
Change your index() with:@app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
comment = request.form['comment']
return render_template('index.html', com=comment)
return render_template('index.html')

nice try, pajeet :^)
How do you select specific fields with the xml parser in javascript?
Like if I have several blocks with a similar naming scheme in a string and want to select them using a logical order.
Example:<!DOCTYPE html>
<html>
<body>
<H1>Conf</H1>
<p>This should be replaced by the Q</p>
<script>
var txt, parser, xmlDoc;
txt = "
<block type="Q_conf_set" id="4u70mA71(#a5h">
<field name="conf_name">example</field>
<value name="Q">
<block type="q6_conf" id="Au+0(n4tlchas#">
<field name="q0">0.1</field>
<field name="q1">0.2</field>
<field name="q2">0.3</field>
<field name="q3">0.4</field>
<field name="q4">0.5</field>
<field name="q5">0.6</field>
</block>
</value>
</block>
"
parser = new DOMParser();
xmlDoc = parser.parseFromString(txt,"text/xml");
qa = xmlDoc.querySelectorAll(".Q_conf_set")[0].querySelectorAll(".q6_conf")[0].getElementsByTagName("field")[0].childNodes[0].nodeValue;
var Q = qa + ", 0, 0, 0, 0, 0";
document.getElementsByTagName("p").innerHTML = Q;
</script>

I'm learning how to implement HTML5 videos to a website, but for some reason when I try playing them on android, I get a message that the video format or mime is not supported.
Source file is .mp4, should I be including a source in a different format for mobile? What would be best in terms of size and format?
>>55237758
.mp4 should be fine.
>>55237758
mime type error is usually a server thing
Does anyone know of a resource on node.js?
I want to know how to get it to work, not how I should write the code.
I want to know about how to set things up.

Pajeets have a hard time understanding it, it seems
>>55237768
Thanks. Do you know if I should be including a smaller resolution file as well, so it loads faster on android maybe?
>>55237784
So I can't diagnose this myself, I'd have to contact the website admin? I'm using HTML and AjaXplorer to do this.

The only people that hate PHP are the ones that have used any language that isn't a retarded_mysqld_convoluted_way_of_doing_stuff1(func). Not to mention it from a language analysis and grammar perspective.
PHP was designed by morons. It has its uses but stop selling it as the best thing ever pajeet
>>55237989
well the kernel version would not affect if the binary is called node or nodejs.
Clearly he was asking about the packaging, so I thought the shortest answer would be to tell him what made sense in the context.
>>55238005

>>55238005
Why are you trying to re-invent the wheel and not use a proper framework?
Maybe a more relevant question:
I have a website (single html file) which takes in a lot of javascript functions. The variables is stored in the browser of whoever receives this html file.
How do I send a variable from the browser to an application on the server?
I was thinking I could use nodejs as I can use sockets from there, but I am not sure I am doing this right.
In the end I should get the value on a C++ application on the server (probably using zmq), but I don't know if I even can do this with nodejs?
Is there a reason that when putting javascript into a site, some things only work when the script is written into the body of the html? I liked the idea of having all js on an external page that I can link to in the header but whenever I do that, I can't get some stuff to run.
Anyone here with advanced web integration experienced?
I'm trying to do the following:

Stop browsing 4chan at work, you will get fired.
>>55238085
You can skip node and just use sockets with C++
>>55238211
okay. How do you use sockets in javascript then?
Are there some good libraries?
I have no problem with c++ to c++ communication, but I am completely new to the web site of things.
Trying to set up a test page with html, and I have two videos centered in one line, with space between them.
When I open it on an android browser and view it sideways, it looks like this. I don't get it, how do I have them aligned, but also have space between them?

I have a question, if anyone would be able to help with an opinion or tip.
I'm using Threejs to render canvas contents to a texture to go on a sphere. Recently realised I need an alpha map to go with it for partial transparency, in some places.
Trouble is, I render these textures in realtime based on users' input, with multiple instances of these canvases, one for each user, before putting it all together onto the texture for the sphere.
I need to be as close to 60fps as I can get.
--
Would anyone be able to recommend which way would be better to go about this, keeping in mind performance:
• rendering both texture and alpha map canvases at the same time, for each user
• parsing the users/final texture and taking out the alpha data, and rendering the alpha map from that
• something else..?
Option 1 seems to be the most straight-forward, and I've started working on that, but it would probably nearly halve the number of concurrent users I can have.
Option 2 seems like the cleaner way to go about doing things, but the textures are fairly large, 4x the viewport size, and iterating through its imageData takes a long time, definitely not a 60fps approach.
--
Thank you for any help, I appreciate it.
>>55238449
>not using TempleOS in his web stack
what is this, 1987?

Doesn't specify an OS (MEME doesn't have a T in it), you can use TempleOS if you want.

question about formatting. The money sign is part of this image. Looks great when customer uses/purchases a gift cert of a 2 digit amount. However if they go 3 digits (100 bucks are higher) the "1" in the "100" overlaps the money sign. I tried moving the amount to the right, which made it looks good for a 3 digit amount, but then a 2 digit amount leaves a large space between the money sign and the amount. Suggestions?
>>55239409
don't make the $ sign part of the image.
use a smaller font for 3 digits to make it fit
>>55239409
Maybe increase/decrease the font-size depending on the length/size of the text? I don't know how much leverage you have with the formatting and how dynamic it might be.
Just a thought if you want your content to fill the circle.
Looks qt btw
PHP truly is the best language.
>>55239438
>>55239444
Thanks. I wrote a script that took care of it//adjust GC price font size if 100 dollars are more
var GCBalanceStr = document.getElementById("ctl00_ctl00_NestedMaster_PageContent_Balance");
if (GCBalanceStr.innerHTML.length == 3) {
GCBalanceStr.style.fontSize = "55px";
GCBalanceStr.style.position = "relative";
GCBalanceStr.style.top = "20px";
}
else if (GCBalanceStr.innerHTML.length >= 4) {
GCBalanceStr.style.fontSize = "37px";
GCBalanceStr.style.position = "relative";
GCBalanceStr.style.top = "35px";
}
>>55237908
Core is being released in a couple days, and it's a huge improvement over MVC5 and previous iterations. You have nothing to complain about.
>>55240168
don't do that.
at least only change the elements class and control it with css instead of hardcoding something like this.
if you're already using asp.net you could do that on the server side.
and why the fuck are you still using webforms.
also you can disable id inheritance in the web.config to avoid having hundreds of ctl00_ctl00 etc.
>>55239409
can't you combine the $ and the number into one string which you center with flexbox?
Lads, which one should I use?
In terms of user friendliness and useful/up to date documentation, which one of these is the best?
>>55240190
it's an older website i guess. Lots of our web apps still use it. I think I prefer having the id inheritance because then I can control what I want and not give it id's manually. I'm pretty new to asp.net. I honestly have no idea how to dynamically format something like this with just CSS. What exactly is wrong with vanilla js?
>>55238352
Koa.js Ember.js Karma (for testing)
It could work
>>55240248
not formatting with css dynamically.
but using classes instead of setting css values with JS.
separate your code and markup.
if you want to change something you now have to dig into the markup/js files to change styling compared to changing it in your css file.
but again, for what you are trying to do you could just make your own server side control that puts its classes exactly like you need already, then you don't need to check with JS.
it's unnecessary bloat.
>>55240297
so i could have done it using just asp.net? do you mind pointing me in the right direction of how i would set up a control that would do this?
>>55237817

I went with compiling both the normal and alpha map. Performance seemed ok, though, I've not tested with many users, so who knows..
>>55240214
Laravel
>>55240356
make a custom class and inherit whatever control you're using now and do something likethis.Attributes["class"] += " price-tag price-tag-" + this.Text.Length;
so you can use the .price-tag class for general styling and .price-tag-2 or .price-tag-3 for whatever text length you have.
why does apache run out of memory even on very low requests?
>>55240248
just admit that youre old and lazy already
Node.js or php as first back end language?
>>55240657
It spawns a process per resource to be served. System processes have a lot of overhead. Use nginx instead.
>>55240671
nah mid twenties. Vanilla js is great. But i found a much better solution anyway. I just removed the Replace method in the aspx.cs file that removed the money sign, and edited the image so it doesn't include the money sign. So now the money sign is a part of the actual text. There's a very slight position difference between 2 digit and 3 digit values, but as long as it's in the circle, it's fine.
>>55240881
Node.js shit. Use python.
>>55240881

>>55238096
HTML is parsed from top-to-bottom and any JS is run as soon as it's read. So any code in a header referencing a body element won't work because those elements don't exist yet.
If you want to keep your JS in the header, you should wrap it in an event handler so the code only runs when the page is ready. If you're using jQuery this is $(document).ready().
You could also move all your JS to the bottom of the page.
>>55237459

Two questions :
I like programming but I don't like Web design much because it's less about programming and more about making a pretty looking website.
Is there something like a GUI builder but for HTML?
And how is asm.js? I like the idea of programming in C and having it translated into Javascript
>>55244657
use bootstrap, or any other css framework that has templates, if you dont like messing with gui
thats not how asm.js works, its just an optimization thingamajig. if you target its "api" you will get better performance (kinda like using simd)
what you are probably after is emscripten, this will translate/transpile c(++), with the help of llvm, onto regular js code (targeting asm.js during the transpiling will produce faster results on browsers that implement native asm.js)
>>55244001
this guy know what he is talking about, online recruiters are a fucking pain.
dont accept to do anything for them unless they ask you to show up on the job site and to talk with their hr or recruiting personnel (and even then its a gamble)

Is using a Controller absolutely necessary in Laravel? Because I've found shit way easier to do it directly like this:Route::get('/blog', function () {
$posts = App\Blog::all();
return view('blog', array('posts' => $posts));
});
Only downside I can see to this is that I cant reuse that same method across different pages without rewriting the same code, but in this case I'd only need it once.

There are a few, but if you can disregard the beauty and readability of better languages then you can appreciate the amazing flow that PHP has, no matter how chaotic it actually is.
You can drool a constant stream of PHP and it will work, but God help you if you want to fix something.
Obviously this is for procedural PHP which is where it shines. OOP PHP has no place in web dev when better languages do exist.
>>55246722
I agree, OOP PHP is cancerous. If you don't need your application to be maintainable, write it in PHP.
>>55247249
If you're working solo then PHP is perfect.

The former for objects, the latter arrays. Arrays also have the 'length' property.
>>55251010
Arrays are also objects in JavaScript so as everything else so it works with them as well. As far as I know the only way you can iterate through the key value pairs in objects is with the for in loop so that's one thing they can do that normal for loops can't, but I don't know if one is faster than the other while using them on simple arrays.
>>55251049
You are missing my point for...in will also iterate over the 'length' property. For arrays use for...of or C-style for loops.

Dot notation is faster to write and clearer to read.
Square bracket notation allows access to properties containing special characters and selection of properties using variables

The correct answer in this case is map, since you're just changing the contents of each element, and not changing the structure of the array you're loooping over.

Because a database, even one that stores json, is more complicated than a file containing json. A database is optimized to be read and written to by multiple users, and to find specific information.
You're not supposed to just load your entire data set into a variable and into RAM and then look through it to find what you want, that's your database's job.

Why do people argue about object oriented vs functional programing? Can't we use both? I'm currently learning them after finishing some basic JavaScript courses but to me it just looks like OOB is how you structure your code while functional is more specific in how you work with your data by using different techniques. I don't see why you couldn't use functional principles in your object methods and so on.

There is no advantage compared to simply procedural software, especially in small scripts that don't need to be extended.
There is up to today no actual proof that OOP improves maintenance or productivity, so best thing you can say is that it offers additional means of extension.

Javascript question:
When I run JSON.parse on a string I'm turning into an object, I lose some detail.
Here's an object within an array within the object:{
"pagemap": {
"cse_thumbnail": [
{
"width": "152",
"height": "136",
"src": "https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTpPziiwMQOplmbDJte-YLQIjEQjZ71oxDLjG3omulap166wnkJv1omlmI"
}
],
"metatags": [
{
"author": "Axis41",
"viewport": "width=device-width,initial-scale=1"
}
],
"cse_image": [
{
"src": "http://www.carrots.com/public/images/homepage/OCT_employee_appreciation_post_image_01.jpg"
}
When I convert that into an object, it becomes{
pagemap: { organization: [Object], metatags: [Object] }
}
What's going on with this?
>>55256048

What's a good way to define a class in JS? There seems to be at least three or four ways. Right now I'm trying to work with prototypes, which seems to give me a better look at a class concept in JS.

>>55256717
babel is command line program you can install which you then run to convert es6 to es5
so you can do this:$babel youres6.js > lib/youres5.js
and if you use a build tool like grunt or gulp you can have them watch your js files and automatically transpile them to es5

I'm receiving JSON data from an API via a node.js http request.
I carry out property accesses on the JSON data and store the results in variables. However, sometimes, the property does not exist on the JSON object for whatever reason. In that case, node throws an error, e.g. " if (bodyObj.items[i].pagemap.cse_image[0].src) {
^
TypeError: Cannot read property '0' of undefined"
I thought I was being a sly fox by sticking these property accesses into if checks, and then assigning a placeholder string if they were undefined e.g.if (bodyObj.items[i].link === undefined) {
// code to assign placeholder string
}
However, this doesn't work. Node just throws the same error as before during the lookup within the if statement clause.
Any ideas on what to do? Am I going to be doing try/catch blocks to solve this?
>>55258821if (typeof bodyObj.items[i].link === 'undefined') { }
orlet myLink = bodyObj.items[i].link || 'placeholder';
>>55258996
A good suggestion, but it still throws the same error:
if (typeof bodyObj.items[i].pagemap.cse_image[0].src === undefined) {
^
TypeError: Cannot read property '0' of undefined
It seems to happen any time the property access occurs. Dunno how I'm meant to test for the presence of something like this if it's going to throw a shitfit every time I so much as dare to check
Cycle.js? Nobody?
>>55259066
cse_image is undefined, not src.
also undefined should be a string, it's not an object.
>>55259086
>cse_image is undefined, not src.
I know. The data I'm looking for will be at the end of this access chain. However, a property could be missing at any point in this chain, in this case it's cse_image, but it could as easily be src.
>also undefined should be a string, it's not an object.
I'm not sure what you mean by this. If I perform a property lookup that doesn't exist, it would return undefined
>>55259143
typeof returns the type as a string, so you have to compare it to the string 'undefined'
you need to check every property on its own before accessing it.
it sucks, but that's how it works.
if you have a lot of objects and keys to check use a function that tests based on a string.

I'm so tired of having to find a job every 2 years.
Why is this field so unstable?
There's always lay offs, off shoring, etc etc.
I'm so jealous of people who have an average paying job for at least 10 years.
I can't see myself ever being able to buy a house or settle down like this.
The grass is always greener on the other side
Someone working the same job for the last ten years is sick of the routine of driving to the same place to work with the same people to do the same tasks. Work dictates a general rhythm to your life, it's not necessarily a bad thing if that shakes up.
