Quickly Find Function Code From The Front End
Jan 8, 2010
When a webpage is calling a javascript function within the <body> </body> tags, is there a quick way to find the code for that paticular javascript function without having to manually search through every external script. I don't have access to the server so I need to find the code for the javascript function from the front end. If it helps you I am using firefox with firebug I also have the web developer toolbar installed.

I have a music site, and on one page surfers can click on song titles and it opens up a pop-up window containing the lyrics (I would direct you to it but it is currently down due to domain name troubles).When you click onto the main window again, the pop-up then relegates to the back - if you click on the same link again, you get nothing, unless you closed the pop-up first.How can I modify my javascript so clicking on the pop-up link will bring an already open window to the front?Here is the popup code currently:
Code:
<a href="javascript:void(window.open('rpages/poar/dragofsloth.html','The Drag of Sloth','resizable=1,width=585,height=420,top=60,left=60'))">1. The Drag of Sloth</a>

When the tabs are initialized by this code:$( "#tabs" ).tabs(); , it displays the tabs in a way that I don't like. I want to trace into the actual 'tabs' function when this is called so I can see why it is doing what it is doing. I have not been able to find where this code is sitting.

I am having some difficulty in constructing a window.confirm() function that works with my code.So if the form data is valid, I need to use a window.confirm() dialog box to show the user's total cost based on the rental rate of equipment chosen and the reservation period. The user must accept the cost by pressing the confirm button, and if user cancels do not submit data.I have written this code but cannot figure out how to find the number of days from the 2 date fields and use that to calculate and display the total cost.
//confirm submit and display rental cost
var equip = document.forms[0].equipment.value
var pDate = document.forms[0].pickupDate.value[code].....

This function takes as an argument a positive integer and returns a
two character string representing the last two digits.
<script type="text/javascript"><!--
function zeroUpFront(nDigits){
temp = nDigits;
if (temp>=100){
temp = temp%100;
}
if (temp<10){
temp = "" + temp;
temp = "0" + temp;
}
return temp;
}
document.write("If you need a two character representation (i.e. 07)
of what may possibly be a single digit (i.e. 7), use the zeroUpFront()
function that tests and returns a possibly amended argument.")
document.write("<p>zeroUpFront(7) returns " + zeroUpFront(7))
document.write("<p>zeroUpFront(11) returns " + zeroUpFront(11))
function convertRep(number){
document.write("<p>zeroUpFront(" +number+ ") returns " +
zeroUpFront(number))
}
convertRep(5445)
//-->
</script>

I see some code examples like this:
<DIV onmouseover="this.style.background='blue'">
and other code examples like this:
<DIV onmouseover="javascript:this.style.background='blue'">
Which way is more proper? Or are both ways perfectly fine? Are there any
specifications that discuss when "javascript:" should be put in front of code?

This is a part of the larger .js code. It fixes .PNG images problem specific to IE6. Everything works fine in Firefox, Opera, IE6 and Chrome. The problem appears only in IE7 and IE8. JavaScript stops executing somewhere after the second line, and the browser reports an error in .js file on that line.

I am VERY NEW to javascript programming as I am to web development. I am pretty decent with VB.Net though. My question is, what are the different ways to call a JavaScript Function either from within XHTML Markup code or from a VB.Net Code-Behind file?

This is a really strange problem i noticed today when adding the last screen into my DHTML app. When i click on a button to hide all of the existing <DIV> tags, and to display the one that i want to currently use. It is doing this, but for some reason or another, it is only being shown for a brief second. and then going back to the main screen. I think this is very strange because there is no event present that should be triggering this to happen. There's not even any code to 'fall through' and inadvertently trigger this, as everything is in different functions.
So here's my code:
The first Javascript file (controls the visibility and hidden aspects of all the <DIV>s)
I also attatched the HTML and the 2 JavaScript files to this message.

I am trying to do the following without html frames.
-Let's say i a html file which contains the structure of a calendar (table, rows, cells, etc)
-Have javascript load the contents of the html file into the page without frames and without disturbing the previous content.
So the advantage is that i would not have to use javascript to create the structure of the calendar but instead to load it so that javascript only have to fill the contents of the calendar.

I've recently picked up HTML and CSS, and am getting to grips really quickly. The principles are really straight forward, you just need to understand a few key principles and then with practice you can remember most tags/elements/attributes etc, although I would rather have the understanding rather then not have the understanding and remember all the tags (I can remember most tags I need anyway.So PHP and Javascript are obviously the next ports of call once I feel I am proficient with HTML and CSS.How hard is it to understand the principles of Javascript and become effective in it?

I have got this great script from the JS anthology Figure 15.13 - folder tree menu. Basically a user clicks on a section link and all the subpages are shown for that section. It is ideal for an interactive sitemap on the homepage.
However, the problem is that when the home page first loads all the links are shown and it takes about 20 seconds for the menu to close up so that only the links to section pages are shown.
Any ideas for how to make only the section pages appear immediately onload?

I'm in need of a solution perhaps with javascript to pre cache my web page content. Which is basically 8 swf files. I need these to load into the browser prior to the page being served. I understand that the best solution would be with preloders within the swf files themselves but I've been through this already with flash developers and this has not assisted. I tested with an html code that reloads the page and that did the trick, but the problem was that the code went into an infinite loop reloading the page every time and I need a solution that reloads the page just ones, and I mean just reload and not refresh because I'm not looking for fresh content but the old content is what I need to stay in the cache.

I would like to include a 'back to page' link on my website.
This link should load the target page when it's not currently open and
set focus to the window if it is.
in pseudo code
win = FindWindow("Products.htm");
if (win ==0) open("Products.htm");
else win.focus();
The page is not in a frame.
Does anyone have any suggestions?

Is there a Jquery method I could use to quickly parse a JSONP object, looking for an embedded object called "error" ?? If I were to do the following:
jQuery.each(query.data.error, function(i,error){ //....}
And there wasNO .error in the returned JSON, what should I expect to happen? Basically, I want to know if "error" is in the JSON and process accordingly.

Not entirely lost in the dark with jquery here, I've done quite a bit with it. The code pretty much looks like this...
$('#created').hover(
function(){
if(y == false)
{
$(this).css({'border' : '1px groove #dfdfdf'});
$('div#csite').show('slide',{ direction: "down" },500);
$('div#sa').hide('slide',{ direction: "up" },500);
};
},
function()
{
$(this).css({'border-style' : 'none'});
$('div#csite').hide('slide',{ direction: "up" },500);
$('div#sa').show('slide',{ direction: "down" },500);
});
//home hover
$('#home').hover(
function(){
if(y == false)
{
$(this).css({'border' : '1px groove #dfdfdf'});
$('div#psite').show('slide',{ direction: "down" },500);
$('div#sa').hide('slide',{ direction: "up" },500);
};
},
function()
{
$(this).css({'border-style' : 'none'});
$('div#psite').hide('slide',{ direction: "up" },500);
$('div#sa').show('slide',{ direction: "down" },500);
});
The div sa is always present (its a sponsor logo). When hovering over a #created link or #parent site link, a div csite or psite comes up, (image representing parent site, image representing creator site). Making them work is no problem however I was wondering ow to change this so that when you are quickly moving from the created link to the parentsite the .hide and .show animation for #sa does not overlap, or does not fire otherwise they get in the way of each other...

I am building a sliding menu with .hover() and I have a series of three functions within handlerIn() and three within handlerOut(). If you quickly run your mouse over and then off of the hover area, without letting the animate() function complete, the handlerOut() functions don't fire correctly.
Here's the page: [URL]
And here's the code for one of the three (all three are the same):
//image sliders
$('#build-nav').hover(function() {
$('#build-trans').animate({top:'180px'},{queue:false, duration:300, complete:

I was using the below code to fade text links in and out on hover. But the problem I'm having is that if you hover over the text a few times quickly the animation will play over and over. How to add a 'callback'(?) so while the animation is still playing it won't fade in/out again until its finished? Or point me in the direction of a better way of doing this effect. Heres the code:
