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?
Can anyone tell me the best way to access a hidden object in a form? I could use a hard-coded index to the elements of the form, but it's too easy to add something before the hidden object and mess up the indexing. For example:
The form has a tagid of "myForm"
The hidden object has a tagId of "myHiddenObj"
I can get the form elements by using
var formElements = document.getElementById('myForm').elements
But there doesn't seem to be any way to do this:
document.getElementById('myHiddenObj')
Assuming I have the elements as obtained above, none of these have
worked for me either:
formElements['myHiddenObj']
formElements["myHiddenObj"]
formElements.myHiddenObj
Anyone have an idea?
I have an object with a member function that changes something on the objects state. This works perfectly fine in the easy case. But when I use an $.ajax call within the function it doesn't work. Here is the example code and failing QUnit tests: [URL]
View 3 Replies View RelatedI'm using an iframe and I have this code in the src file for that iframe.
HTML Code:
if (parent.location == "http://domain.com/store.html"){
document.write("********************************");

I've tried self.parent.location, I've tried parent.window.location, I've tried parent.location.href, none of it works.
In parent window
function f1()
{

Inside IFrame
$(document).ready(function()
parent.f1;

The above works without any problem But,I am getting the "TypeError: f1 is not a function" on accessing the below code

Suppose I have the following HTML code:
<div class="one">
<a href="http://jquery.com/">jQuery</a>
</div>
<div class="two">
[Code].....
Basically I want to recognize which <div> tag was double clicked, and hide the corresponding link that is nested within that specific <div> tag.
The only way I can think to do this currently is to basically copy and paste a whole bunch of jQuery code for each <div> tag and it's sub-elements (links in this case).
I am trying to access an element in a page using ID using jquery in when the document is ready.But the problem is the length is always 0 even if the script tag is in the head or right at the bottom of the page. The element is seen rendered when I see it using FireBug.an someone point out where I am making a mistake accessing the element
$(document).ready(function() {
alert('Hello World");
$('#id').live("click", function() {
[code]....
Bit of a problem I've not been able to solve after a couple hours. I'm new to Javascript classes and objects and really a Perl programmer so this has been giving me a headache. I've attached the code below but in a nutshell I have an object that writes code to a div upon instantiation and attaches events to several controls. When the event fires it runs a function attached to the class via prototype.
Problem is, the "this" obj from this event now refers to the control (e.g button) so there is no way to get back to the class. If you look at " alert(this);" line this should output the Class object, instead it refers to the button
I have got a following problem with using javascript:

I could use a hand changing the display property of a group of objects based on classname. What I have here doesn't work; perhaps you can see why? I think the basic problem is that I don't know how to access the objects properly.. Code:

The scenario is of two different web servers. The parent frame (html
page orginates from server 1) has script like
function x1()
{
.....
alert('parent invoked');
....
}
Inside child frame (html orginates from server 2) the html refers to
parent script like
{
.....
parent.x1();
....
}
It throws Microsoft Jscript runtime error: permission denied. I am

In this game i have the letters as images and they are listed at the top in two rows.
This is the code
As this is not really the best way to do it, I was wondering if i could set the letter squares to be objects of a Button class. I just don't know how to do it.

I'm new to this jquery malarkey so I'm shooting in the dark somewhat here.
I need to change the class of the 'a' tag within the li that has the nested ul e.g
<div id="menu-container">
<ul class="main-menu">
<li>Link 1<a class="menu"></a></li>
<li>Link 2<a class="menu"></a></li>
<li>Link 3<a class="menu"></a>
<ul class="sub-menu">
<li>Sub Link 1<a class="active-menu"></a></li>
<li>Sub Link 2<a class="menu"></a></li>
</ul>
</li>
<li>Link 1<a class="menu"></a></li></ul></div>
I need to change it to "active-menu" and the nested a to "menu". I cant change the HTML at all, I wish I could.
why I'm not able to remove the class "hasLink" from the parent element that contains the class ".test"
<ul>
<li class="hasLink">
<div>
<a href=" class="link">link</a>
[Code]....
<ul id="menu">
<li><a href="#"><strong>Electors</strong></a>
<ul>
<li><a href="A.asp">Conditions Required</a></li>
<li><a href="B.asp">Verification of Entry</a></li>
<li class="submenu"><a href="#">Special Measures</a>
<ul>
[Code]...
With the above code, i want to add the "active" class to the <li> tag related to the current page. "get_cur_page" is an ASP function that returns the page so if you are on the page J it will return J.asp.
I cant get this code to work, the goal is to have the "active" class applied to the <li> tag surrounding the active page's link in the menu.
I understand that using
Code:
.parent(".class")
I can select the parent of the current element if it (the parent) has a class named "class". How can I select parents that don't have a certain class? Also, how can I select parents that don't have more than one class? Does the .parent() method allow to do this?
I was wondering how to access parents class variable. For example:
Code:
function Class(){
this.variable; }
SubClass.prototype = Class;
SubClass.prototype.constructor = SubClass;
function SubClass(){
this.secondVariable = Class.variable; <-how to access parent variable?

I'm building a volunteer translation site. In order to constantly update only paragraphs that multiple translators are working on, I need to pass an array to PHP of A: which paragraphs are open, and B: which translations have been submitted and are visible on the user's screen. PHP will then compare this with what is in the database and tell jQuery to add new submitted translation paragraphs or remove deleted ones.I've managed to make a string of all the open Div's and have it updated every second, like this:
function cycle(){
var data = '';
$('.paragraphtobetranslated:visible').each(function(){

I want to post the class of the parent ul and the clicked li to php when they are clicked say as "model" and "part". I'm sure its simple but i cant seem to quite grasp how to do it.
I want to remove the class-attribute of all <a>-tags in this table-tr:

How I have to handle it?
