I have the following code in one of my pages. My problem is caused, because the method "processEvent" is never called, but I have no idea why. I guess it is broken, because I don't relay the "this" object correctly.
<script type="text/javascript">
var MyClass = function()
{
this.init = function()

I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?
I've got a script which is called by a keypress event, something like this:
<html>
<head>
<script type="text/javascript">
function respondToKey(e) {
keyPressed = String.fromCharCode(e.which);
if(keyPressed == 'g'){
alert('you pressed the g key');
window.open('http://google.com');
}
}
</script>
<title>Untitled</title>
</head>
<body onkeypress="respondToKey(event)">
hit the g key to open a google window
</body>
</html>
when you hit the right key, the alert appears, but the window.open() never happens. There's not even a message in the Error Console, just nothing.
Is this a security feature? Any way I can get around it? And, if it's a security feature, is the fact that it fails silently with no error message also a security feature? Because it's rather annoying.

I need to use the this keyword to differentiate which div class name needs to show. Currently, my code below on '.bioclick' click event, every bio_desc is displayed or showed. I just want to show the current clicked'.bioclick' child '.bio_desc'. I tried using the this keyword but it did not work.
$('.bio_desc').hide();
$('.bioclick').click(function() {
$('.speaker_wrapper').children('.bio_desc').toggle
('slow');
});
});
here's the one of example codes from documentation:

As soon as I add this line of code, .selected is nothi-lightedany more. Now, I understand that this is the way this function is supposed to work (guess so,otherwiseit's a bug), but I couldn't find any function in documentation that would go from my current element to the first element that has that classapplied and skip everything in between.
I attempted to invoke a C# method using jQuery but it failed. The reason is because the method cannot be found. However the method exist in the class. Did I miss something?

How to call a method from JS through UpdatePanel with jQuery? I cant call WebMethod cause it is static (I have a custom control and it is statically inaccessible).
What I have: Custom control on a ASP.NET website in UpdatePanel
What I need: User clicks on a link and JS does its magic and than I have to post (AJAX) changes to server (custom control). How do I achieve this with UpdatePanel (I cant jQuery ajax call) - how can I call a method on server with some arguments from JS?

View 1 Replies View RelatedI got help with creating a method (to have only increments of 10 as valid values for certain fields in the form).
jQuery.validator.addMethod("roundnumber", function(value, element, params) {
return (value % 10) == 0;
}, "Your order of vaccine must be in increments of 10");
I've also found info on how to add rules to a class (there are multiple fields and name generated dynamically so I have to use class).
jQuery.validator.addClassRules("fluzone_", { roundnumber: true});
So I've added both these lines to additional-methods.js, but it does not validate it on submit. I do have php back-end logic that sets values to the nearest round number but I do want Js navigation before submission.
I am calling an AJAX function from a certain method, but for any reason it does not return the result.

I'm using jquery-1.3.2.min.js and everything works perfectly in browsers other than Explorer... It's not liking this part:
this.appendChild(E)
function(){return this.domManip(arguments,true,function(E){if(this.nodeType==1){this.appendChild(E)}})} ... }

I have a jQuery script which works fine online, but when it comes to testing locally I get this error on the 2nd line of code:
Uncaught TypeError: Cannot call method 'hide' of null
So, that means I'm trying to call a method on something that doesn't exist, or is set to null. But I'm trying to call the method on anything with the class menu. And there are divs with the class menu on my page. The script runs fine on several other pages, so it must have something to do with this page in particular, but I have no idea why...
Here's my HTML:
Code:
<div id="navigation">
<ul id="navbar">
<li><a href="[URL]">Home</a></li>
<li><a class="drop-down" href="#">Food Menu</a></li>
<li><a class="drop-down" href="#">Drinks Menu</a></li>
<li><a href="gallery.html.php">Gallery</a></li>
<li><a href="function.html.php">Function Room</a></li>
<li><a href="contact.php">Contact Us</a></li>
</ul>
<div id="drinks" class="menu"> .....
And my jQuery script:
Code:
$(document).ready(function(){
$('.menu').hide();
$('a, #header').not('.drop-down, .menu a').hover(function(){
$('.menu').hide();
});
$('.drop-down').mouseenter(function(){
$('.menu').hide();
id=($(this).text().toLowerCase().replace(' menu', ''));
$('#' + id).show();
});
$('.menu').mouseleave(function(){
$('.menu').hide();
});});
I've put up the page online, but I don't have a direct link to it because it's a live site. You can see the code working here: The Pilot, and the offending page is here: The Gallery.

View 2 Replies View RelatedI'm trying to create a list that contains items which are filters for a search. The list shows 10 items (max) on the page load. if there are more than 10 it changes the class of the elements > 10 so they are hidden, and a 'show more' link is appended. Now if the user has 'unhidden' the previously hidden items and then chooses one, I want the class for all those previously hidden items to change until the user has deselected that item.

I have been wondering if there is a way to make the following javascript functions work in IE8 and Chrome:
var funct = function()
{
var ppt = new java.awt.Point(200,100);
alert(ppt.x);
}
This thing works only in Firefox. Is there a way to enable global Java packages in IE 8 and Chrome?
