I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?
View 1 RepliesI am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
Is it possible to access the parent context within $.post to asign the result to the parent selection?
See this code here:
$("a[href='country#']").click(function(event) {
var dieBusinessUnit = 'THIS VAR SHOULD CONTAIN RESULT OF $("businessunit", xml).text())';

I have UL tag:
<ul id='ul'>
<li id='li1' class='someclass'>
li1</li>
<li id='li2' class='someclass'>
[Code]....
Now we have alerts only for three old elements. This is clear. Because these elementes have been initiated before page generated. But the new one is ignored.
The question is - how i can add new elements to the UL list? It would be glad if "jQuery.each" could read four and more elements - not just the first three initiated elements.
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
i have function appended to a click event of more than one objects. How can i check if the object that was clicked has a certain class xy?
var t = jQuery(this);
jQuery(t.children()).click(function(e) {
if (??check if the element that was clicked has class xy??){}
}
If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?
Example:
// Function that takes a JQ object and makes it sortable.
// We assign the "SortableRecieve" method to the receive event
MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve
});}
MyObject.prototype.DoSomething = function(){
// Does something important
}
// The actual function that gets called when the receive event occurs
MyObject.prototype.SortableRecieve = function(event, ui){
// This function call won't work, because "this"
// doesn't point to the right thing!
this.DoSomething();
}
So how can I access the "True" this that refers to the object?
I have very simple question (ie probably simple for everyone with jQuery experience, but not for me). Lets say I have the following list
<div>
<li id="first"><a>one</a></li>
<li><a>two</a></li>
<li><a>three</a></li>
<li><a>four</a><li>
</div>
Now, if I want to get all the list items after the first, and change the text within the anchor tags, if a certain condition is met (eg change to capitals if it starts with a "t"). How can I do that? My approach was to get all the list items (after the first) with

I have the following:
<html xmlns="http://www.w3.org/1999/xhtml">

{
var s = document.getElementById("form1");
s = s.text1;

alert("Post data! " + s);
}
//-->
</script>
</head>
<body>
<form action="" method="POST" id="form1" >
<p>When the checkbox is checked, you are prompted to enter a value</p>
<input type='text' id='text1' value='enter amt' maxlength=ཆ' tabindex=Ƈ' />
<input type='button' id='btnSubmit1' value='Submit' onclick="btnSubmit1_onclick()" />
</form>
I want to put the value I get in a field on the page that opend this, how do I do that?
sorry but how to access text field with $() ??
<form name="mainForm">
<input type="text" id="testField" name="testField">
</form>
<img onclick="document.mainForm.testField.value='blah blah text'>
so instead of document.mainForm.testField.value, with jQuery, is it $('#testField').value ??? i know $('#testField').value doesn't work

I'm new to web programming in general, so bear with me as some of my methods may not be entirely correct. What I currently have working is I have a webpage which contains a DIV, which I am using to load another webpage via javascript(which calls itself, in order to get an auto-refreshing effect). The webpage that's being loaded is detecting if a process is currently running on the server and writing some console output while it's running, and what I want to do is stop the auto-refreshing when the process completes. (I can detect when the process stops already).I'm trying to figure out how to properly set this variable from my page that's being refreshed, since it's being loaded in a DIV I figured there has to be some way to retrieve the parent's information.

View 3 Replies View RelatedI am developing a web application with full of independent widgets in form of iframes. I would like to avoid embeding jquery (and jQuery UI) in each iframe's head to reduce number of requests and want to use the libs from the parent window instead. In iframes' head I tried the following code:
window.$ = window.content.$;
window.jQuery = window.content.jQuery;
Well it works but naturally as the jquery object belongs to the parent document I can manipulate only the DOM nodes of parent document from the iframe and not the DOM nodes of the iframe itself! I think if I could replace the "document" object of "window.$" with iframe's "document" object it would work!
1) Is "=" copy by value or by reference? If I succeed to replace the "document" object in "window.$", will it be also replaced in "window.content.$"?
I have a webpage with an IFrame in it. The content for the IFrame could change per page and with it size. I don't want scrollbar's inside the IFrame but rather for the whole page. To accomplish this I must resize the height of the IFrame (width = fixed). But I can't seem to accomplish this. The links within the Iframe load the new content but I have to access the parent document to be able to resize the IFrame height. How I can resize the iframe from within javascript in the IFrame.

View 3 Replies View RelatedI'm new to jQuery and Javascript overall, I have searched the internet to make use of jQuery instead of the HTML's iframe tag. My problem is links inside a .load file, I want them to refresh the box on the index.php file, not the file itself (in this case the links are in blog.php)
Here's everything I can provide with:
Files:
"index.php"
"blog.php"
In my index.php file I have this script to make my index.php links open the required file in my div box.
"index.php"
<script language="javascript" type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#html").load("blog.php"); // shows the blog.php when I first enter index.php, which I want to have
$(".link_click").click(function(){
$("#html").load($(this).attr("id"));
});
});
</script>
Here's "index.php" link:
<a class="link_click" id="blog.php">Blog</a>
Here's my div box in "index.php" where I show the information within the loaded file:
<div id="html"></div>
All this works, but here's my problem, I have multiple links within "blog.php" which I want to make "index.php" to refresh the "index.php"'s html div. Is there some kind of way to edit the "blog.php"'s script to make it "index.php" the parent or reference?
"blog.php"
<script type="text/javascript">
$(document).ready(function(){
$(".link_click").click(function(){
$("#html").load($(this).attr("id"));
// Need to change this(?) to make it reference the index.php's html div box
});
});

I have 95 different objects like this one:
obj1Object = {
name: "some name",
type: "type",
picid: "001",
maxvl: 500000,
minvl: 5000,
clsid: 1,
movable: true,
size: [45, 45],
note: "Some text here"
}
Now what I need is to access these objects only when I need then. Right now they all load when accessing my program so all 95 of them are "somewhere" in memory.
