What is the JavaScript equivalent to the following PHP code:
$expTime = time() + (5 * 60 * 60); // now plus 5 hours (5 hour; 60 mins; 60 secs)
$expTimeStr = gmdate('Y-m-d\TH:i:s\Z', $expTime);

I've created a stock ticker function and need to call it every 2 minutes.
I've succeeded in doing this with the javascript setInterval function, but the problem is on the first call it waits 2 minutes before calling the function, whereas I want the first load to be called right away.
function CallFunction() {
setInterval("GetFeed()", 2000);
}

How can i achieve http://jdstiles.com/java/angledtext2.html this kind of angle(slant) using html , css and javascript. In design we have tabular structrer and by clicking on a tab the area beneath should refresh without reloading page (some thing like jquery or ajax).
For example,
<html>
<body>
<img id="pic" src="original.jpg"/>
</body>
</html>
In Javascript (jQuery):
$("#pic").attr("src","newpic.jpg");
Now, is there a way to reset #pic's src to original.jpg without explicitly setting it as $("#pic").attr("src","original.jpg");?
Is there is way to compress JavaScript code?
e.g.
function test(){
// some code here
}
after compression it should be
function test(){//some code here}
Also, I need vise versa at the time of editing the code.
I work in Javascript with integer numbers only (mainly adding numbers and shifting them). I wonder how big they can be without loosing any bits.
For example, how big X can be such that 1 << X will represent 2^X ?
I'm using a classical javascript prototypal inheritance, like this:
function Foo() {}
Naknek.prototype = {
//Do something
};
var Foo = window.Foo = new Foo();
I want to know how I can improve this and why I can't use this model:
var Foo = window.Foo = new function() {
};
Foo.prototype = {
//Do something
};
Why this code doesn't work? In my head this is more logical than the classical prototypal inheritance.
Hi
Does anyone know what's the replacement method for FB.CanvasClient.startTimerToSizeToContent() to resize iframe content in the new javascript SDK for Facebook?
Or maybe if there is an alternative technique for achieving the same effect?
Thanks
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
I got the Wrox.Beginning.JavaScript.3rd.Edition and wanted to start learning it from scratch, then my boss came along and said that why bother, learn jQuery.
Can I understand jQuery and work with it although I am a newbie and have limited knowledge in ASP.net, vb.net, some C#, and basic HTML?!
I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority.
The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one.
Has anyone done a performance comparison between any of these?
I have a 24 hour time string (ie 16:30) and would like to add x time blocks of 30 mins. For example if x = 4, then 16:30 + 4(30) = 18:30. Is there any easy way to do this with out exploding the string and doing if statements for mins/hours.. etc? Also this is on a php page would it be easier to do this in php then echo it to the javascript?
Thanks for the help!
in a code which i am goin through there is a link has href=javascript:; in code.when it is clicked it opens a lightbox to show some msg with close button.how is it done.I think this uses dojo
My layout breaks if I change the window size in IE7/AOL, so I added a simple javascript function that fires on window.onresize, but no matter how I change the location I get problems.
It was suggested I post a link and here it is:
link text
I already use PHP to detect browser and include an IE7-only inline stylesheet (and for mobile browsers), and my page looks nearly identical to the way it does in FF, Opera, Chrome, Safari and IE8, but when I change the window size, some things go wonky, and come back into line if you refresh. Any advice is welcome :)
Hi,
In my html, I have an html element with a mouseover event handler.

I'm making a call to PayPal's credit card processor, and after a successful/unsuccessful transaction it returns me a string that looks like this:

I'm not a javascript pro, but how exactly can I turn that into a parseable array?
Thank you!
