noapparentfunction posted:I have a relatively simple slider code on this test page I uploaded. It uses jQuery, but my only problem with this premade application is that it uses those rounded browser buttons to operate. Is there a way to convert these to standard links, preferably ones that use images? I think you could use an onClick=function() on pretty much any HTML element instead of checking each of the buttons to see if they're clicked.

I recommend that you not bother trying to do that yourself and instead use jQuery with the validation plugin. It's dead simple and looks impressive on the page, too.

I'm trying to keep track of the URL of a frame on my page. Is it possible to do this with JavaScript?php:<?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
alert($("#inside").toString());
});
</script>
</head>
<frameset cols="100%" noresize="noresize">
<frame id="inside" src="content.php">
</frameset>
</html>
?>All I really want is the URL. What should I be doing instead?

Thanks, Lumpy. That's the explanation I was looking for. I hadn't done any (serious) JS in a couple months and somehow had the idea that everything was a global.

I think NYT's website does something like that for word definitions when you highlight text. Maybe you could take a peek over there and see what's going on.

Have you written an encryptor in another language? Try doing a line-by-line straightforward port of it to JS. Next, read a book or two on JS and see if you can't go back and do it again with a better understanding of scope and prototypes and perhaps a library like Parallel.js

When it comes to animation, setTimeout is a bad habit. If you're targeting modern browsers, requestAnimationFrame is a much better option https://developer.mozilla.org/en-US/docs/Web/API/window.requestAnimationFrame What you're already doing probably works fine, but this is worth investigating when you want to take your animations to the next level.

"e-12" is scientific notation. It means "x10-12" What you'd expect from real arithmetic is zero, but what you're getting back instead is an extremely small number due to floating point arithmetic. Computers only represent integers as exact values; other numbers are stored as approximations that are close enough for most purposes. http://en.wikipedia.org/wiki/IEEE_floating_point

You can avoid the recursion problem by handling this inside a for loop. Use jquery's ajax method synchronously and they'll fire one-by-one as many times as you need. This is going to take loving forever, but it sounds like that's out of your hands

Sounds like something that should be handled server-side. Deal with the form inside your one-page app, then provide a link to another page that serves a file, perhaps? Maybe add a parameter to the file serving page to require a disposable key.

stoops posted:I did this in php with a preg_split. Is there something like that in javascript? Not sure how to answer the rest of your question from the top of my head, but here's a start on that string split: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split Javascript splits strings with either another string or regex from the same method. It's really nice.

This thing looks promising: http://spy-js.com/ Does your code do lots of scope traversal? Getting variables from above the current scope is a common source of JS performance problems. You could try making local copies if that's what's happening. Does any of your program iterate over large sets of data that don't need to be processed in any particular order? Running the computations in parallel may help as well: http://adambom.github.io/parallel.js/

loquacius posted:I've fooled around with the idea of using JQuery to spit the object's markup into the parent document, but that's not a good solution since the iframe's content comes from a different server That won't work, either, since you can't read the contents of an iframe on another server.

Two problems: there's line numbers in your JS and the JS was set to run onLoad, but your binding of the behavior is right in the HTML. Binding a function in an attribute only works for functions that are already declared, not tied to the load event, so switching it to <head> solves the problem. You might not understand that second part at this point in your learning, which is perfectly normal.

Node is a language/server combo like Python + Gunicorn. You'd need to find a heavy backend framework like Django for Node that has a similar feature.

FSMC posted:I'm writing a browser bookmarklet/extension and have just started using unit tests. Sounds like you've got a problem either selecting the right section of the document or parsing its contents? You could include as part of a your tests a set of copy/pastes of input data that would normally come from the service you're scraping. This is sometimes called a "fixture." Add a couple consts or functions with a couple versions of passing and failing data as appropriate and then write and test the functions that parse it. Testing the fetch code could be harder, but if you've really separated the fetching logic from the parsing logic, there shouldn't be much room for error. I usually say skip the tests that interact with 3rd party services if the rest is solid.

Wordpress ends up being pretty slow as an API backend. Each request fires all the same hooks as a full pageload. I've heard of better experiences doing headless Drupal, but I don't really like using CMSes in general myself.
