In PERL there is a 'die' function that stops execution of a program if certain conditions are not met.For example, a needed file is not found because it is miss typed.Is there a similar function for javascript?The code I would think would follow something like this:
Code:
var FileName = ''; // might have expected to enter something like 'ExternalFile.js' from a Querystring
[code]....
I'm playing around with forms and wrote a JavaScript
function that loops through all form elements and displays every option
in every select field with an alert for each one.
var els = form.elements;
var l = els.length;
for (var i=0; i<l; i++) // loop through all form elements
{
if (els[i].type.substring(0,6) == 'select')
{
var options = els[i].options;
for (var j=0, len=options.length; j<len; j++)
{
alert(els[i].name + ' option ' + j + ' = "' + options[j].text + '"')
}}}
In the form I am using this results in many alert boxes popping up.
This seems like a very, very basic question, but I've Googled it quite a
bit and can not find an answer. Is there a way to manually abort that
script (other than closing my browser) or do I have to keep clicking OK
until the loop has run it's complete course?
The documentation for $.ajax() says that when the error callback is invoked, the error string may be null or one of "error", "abort", "timeout", "parseerror". So naturally, I assumed that if I were to call .abort() on the XHR that $.ajax() returns, the error string in the error callback would be "error". But that seems not to be the case. What I'm seeing, in jquery-1.4.4, is "error" as the error string. Has anyone else seen this problem? I'm using the most recent Firefox on MacOS X 10.6.

This is my first time using jquery and Ive designed a small and simple fadein/out script that acts as a rollover on this navigation bar: [URL] Here is the code:
$(document).ready(function() {
$(".navbutton").not("#active").hover(function(){
$(this).siblings(".rollover").fadeIn(300);
},function(){
$(this).siblings(".rollover").fadeOut(300);
});
});
It works great. However, if a user quickly moves their mouse over the nav buttons and repeats the process, the rollover affect will fadein/ out over and over again until its completed the cycle the amount of times the user moved the mouse over the button back and forth. I wish to change this behaviour so that, somehow, the processing is aborted if it is noticed the mouse is not present after a fadeout is completed.
I'm writing a small async webapp. in JavaScript and I'm using <script> element technique to load data. I'm usign <scriptbecause of cross domain restrictions with XmlRequest.
The problem is when I remove a element that is currently loading from DOM (with removeChild) Firefox still loads it and waits with other scripts.
What I want is to break this process and load a new data without waiting for old one.
Here is example script:
I have a function, something like this:
function temp(){
$ajax_request.abort();
some operations
$ajax_request = $.ajax({url: url, type:'POST', dataType: 'json', data: {...}})
success(function() { alert("success"); })
.error(function() { alert("error"); })

Normally I would abort my request this way:
Code:
var myRequest=new XMLHttpRequest;
...
myRequest.abort();
But how would I abort my request when I'm making it using the Ajax Toolbox library? In their documentation I saw there is "aborted" which only tells me whether the request has been aborted or not so there must be a way to abort it.

I have some javascript the works in conjunction with a flash video player. When a user selects a video in the Flash video list and new video is called and begins to play. Also, when that video is selected a function called "doOnMediaLoad()" is called and inside of that function I have put a call to another function that I wrote in the same script.function that is called when user selects flash player video list.
function doOnMediaLoad(e) {

I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below

function loaded() {
console.debug("in loaded function");
}

window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.
I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).
Code:
The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:
Code:
...it still doesn't wait.

I am trying to minimize the amount of script that I use on my website. I have sections of each page; each section has the same basic layout. The divs and images that I want to make appear and disappear all have nearly identical ids, the only difference is the number at the end of the id.Is there a way to get one script to automatically detect which id number has been clicked and then show all elements with the same number at the end of the id? I would also like it to hide the elements in the hide function below (basically they are the elements that do not share the same id number).I currently have everything working the way I want it to using multiple functions like the one below but I woul

I have 2 javascript files: 1 containing generic functions for my site used sitewide and another for a particular web page containing just the javascript for that page. The page is also calling the jQuery javascript file.

I am having a strange problem with a javascript function that does not return the value but returns the code inside the function.

I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.
I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.
This post is where I was doing something similar to save repeated code: [URL]
In a similar way is there a way of passing in a function name to be called on success?
