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

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 a form in which there are two radio buttons .
On selecting the first radio button1 , two textboxes are displayed ( textbox1 & textbox2 ).
& On selecting the second radio button2 only One textbox is
displayed (textbox1) & another one (textbox2) get hidden .
what i am trying to do is that when radio button1 is selected & so two textboxes are displayed, then Onsubmit throw alert for two textboxes seperately , to Enter value in them if this text boxes are blank .
But if radio button2 is selected then throw alert for Entering value for only one text box (textbox1) if its value is blank , & Skip alert throw for the another one hidden textbox(textbox2) .
how i can achieve this using JS .
in moz/nn, this errorsvar el = document.getElementById;
why?
pointers to core classes and/or singletons seem fine; this works for examplevar ord = String.fromCharCode;
alert(ord(100));
Input values to match args array or throw an alert. This is what I have but I want the alert to refrence the var args= or throw the alert.
function qtymultiply(qty){
var fs=qty.parentNode.parentNode;
var subtotal=document.getElementById('subtotal');

I want to change a db record when the user leave the website. I have this PHP script:
<?php
require_once("../config.inc.php");
if (isset($_POST["user"]) && isset($_POST["ip_address"])){
$query = 'UPDATE users SET logged = 0 WHEREuser= "' . $_POST["user"] . '" AND ip_address = "' . $_POST["ip_address"] . '" AND confirmed = 1;';
mysql_query($query, DB_LINK);
}
?>
And this jQuery script:
// script da includere in tutti i file delle pagine per l'utente loggato
// cambia lo stato dell'utente da loggato a non-loggato quando viene chiusa la finestra del browser
$(window).unload(function(){
$.ajax(AJAX_PATH + "logout.php", {type: "POST", data: "user=" + escape(USER) + "&ip_address=" + escape(IP_ADDRESS), success: function(){alert("Arrivederci!"); return true;}});
});
but it doesn't seem to work.

But as soon as I throw in the onComplete stuff fancybox fails to work.
I am trying to throw an alert with the attributes of a submit button in the alert.
What am I doing wrong?
It prints 0,1,...,9, but you cannot see the word "hi". It seems that it prints "hi" then executes the listnum function. But the listnum function is placed before "hi". Could you
give me some info on order of execution?
<HEAD>
<SCRIPT language=JavaScript>
function listnum() {
i=0
do {
document.write( i + "<br>")
i++
} while(i<10)
}</SCRIPT>
</HEAD>
<BODY onload=listnum()>
hi
</BODY>

I would like to have two buttons on the page. When visitor clicks on first, I would like to start looping through numbers for example from 1 to 100. When loop gets to the end, I would like to start it over and stop it when user click on the next button.
My concern is if this is safe. What if user waits for 1 minute or more to click the second button which should stop the loop and pick up the number where it currenly is? Will it cause browser to warn user that the script is slowing down the browser? How can I avoid this?
I have a site and in that I don't want to users pressing tab key and also shift + tab key. So I need a small javascript code for preventing execution of tab key and Shift+Tab Keys.
