I am trying to assign a variable to a jquery object that is found using the children() and eq() methods. This is a simplified version of the html structure.[code]Here is the jquery code. All I want to do is assign an object to the variable and be able to manipulate the object through the variable. [code]Again this is a simplified version of my code but the structure is similar.

<div id="menu">
<ul>
<li><a id="home" href="#">Home</a></li>

How can I grab the immediate li children only and not all of the li that fall in this object. The following gives me every single <li> which is not what I am looking for.
(function($){
$.fn.extend({
myplugin: function(options){
return this.each(function(){
// the object we are working with
var obj = $(this);
// get a list of menu items
var menuItems = $('li',obj);
});
}});
})(jQuery);
I'm trying to create a function that will return the value of responseXML so I can assign a variable to it.
Code:
ajax.downloadXml = function (url)
{
var XMLHttpRequestObject = false;
[code]....
Stepping through the function, the onreadystatechange seems to never be executed, so nothing is returned. There's probably just a fundamental I'm messing up on.

IE has no problem with this, but Firefox throws an exception - "Illegal operation on WrappedNative prototype object". Is it within its rights to do so?
how to assign a value to a global variable within a function and can't seem to figure it out. Here's my thought,
<script type="text/javascript">
var global1=""; var global2="";
function assign(vari,strng){

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.
integrating PHP-HTML-JS I'd need some help for doing the following:I have a index.php including:
<script type="text/javascript">
function filter (phrase, _id){
var words = phrase.value.toLowerCase().split(" ");
[code]....
and a child.php including a table object with the id LIST.I'd need to change the parent.php in order to filter on real-time the table LIST via the FILT input on the parent form. I have tried different values instead of 'this' on the js function calling but nothing succesfully.
Here's my object constuctor:
function suggest_object(result_id)
{
this.in_result_div = false;
this.search_element = document.getElementById(result_id);
}
And the execution code:
var suggest = new suggest_object(result_id);
document.getElementById(result_id).onmouseover = function(){suggest.in_result_div = true;}
It works as is, but i'd really like to be able to set the onmouseover inside of the object. Something like
function suggest_object(result_id)
{
this.in_result_div = false;
[Code]....
So how can I get the 'this' inside the onmouseover function to refer to the object?
Is this
Code JavaScript:
function x(event){
if(typeof event == "undefined"){[code]......
I've got a piece of code where, for all the world, it looks like this fails in IE 6:
hometab = document.getElementById('hometab');
but this succeeds:
hometabemt = document.getElementById('hometab');
Has anyone ever seen anything like this before, or am I dreaming?
I 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 there any way to get the variable name of an object from inside the object?
[Code]...
I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';
var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(this).attr('title');
$(".image-holder").css("background-position",'sprite.top, sprite.left');
It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.
what I have is this function which reads the JSON attributes of crab_house, a JSON object:
But what I would like to do is something like:
I have a function that takes parameters of what the form name and the form object name is and then modifies the form accordingly. Now I can make it work fine if i make a separate function for each form object, but that seems very cumbersome. This is what I have
document.formName.formCat.selectedIndex;
i want formName and formCat to be variables so I can specify in the parameters which part of the form to deal with, but i get an erorr. Is this possible?
How can you use an integer as an object? The idea is to create dynamic object according to a particular id which is an integer
var newObject = function(integer) {
window.integer = {};
}
I cannot console.log(window.123), only console.log(window.integer) ...
how I create the object window.123 or perhaps, window.id_123 ?
i want to get the ids of all the children of id 'top' and store it in an array in the order listed above. so final output in this case would be:
arr[0] = 1
arr[1] = 2
arr[2] = 3
is there a function or simple procedure that help me do this?
I have a div containing many children all very different, each one as a different width. I need to get the width of all the children. I mean child1.width() + child2.width() + child3.width() etc... Of course as a new child can be added anytime I can not use the kind of things I put above.
I tried that among other things :
$("div.mydiv").children().width();
But I only get the width ofthe first child.
How is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?
var MODE_CREATE = "mode1";
var MODE_UPDATE = "mode2";
var MODE_DELETE = "mode3";
var oIcon = {
MODE_CREATE: "create.gif"
, MODE_UPDATE: "update.gif"
, MODE_DELETE: "delete.gif"
};
var oTitle = {
MODE_CREATE: "Create a new item..."
, MODE_UPDATE: "Update this item..."
, MODE_DELETE: "Delete this item..."
};
I'm looking to do something like this:
function superDuperObject(range) {
this.startContainer = new superDuperObjectStartContainer(range);
}
function superDuperObjectStartContainer(range) {
this.calculatedContainerNumber = doSomethingAndGetSomethingBack(range);
return range.startContainer
}
function doSomethingAndGetSomethingBack(range) {
return
someCoolInformationThatICalculateInThisFunctionTha tNeedsTheRange;
}
var myObject = new
SuperDuperObject(DOMRangeObjectThatIDefindedEarlie rInCode);
// Show me the startContainer of
"DOMRangeObjectThatIDefindedEarlierInCode"
alert(myObject.startContainer);
// Show me the calculatedContainerNumber that I get from a function
that does stuff with the range passed to it
alert(myObject.startContainer.calculatedContainerN umber);
I have an error when I try to make:
CustomObj =
{
is_all : Compatible(),
Types :
{
PASS : CustomObj.as_all ? "ok" : "onok",
...
...
...
but in an object literal notation I cannot use a parent object
variable? or
can I do to create a global variable inside my parent class
(CustomObj) and
than to use in my children objects like Types?
I need to acsess an object property via variables, but don't get ahead.
Example:
var property = height;
"height" is a property of the object "flower". Now, I need a possibility to access "flower.height" with my variable property, means -->"flower.property" I tried everything like "flower.[property]" "flower.['property']" etc. but nothing did help.
I am fairly new to JavaScript, have been using VBscript before and JavaScript comes off a bit illogic...
Anyways, here's what I am trying to do:
function TestFileType(formname) {
fileName=document.[formname].img1.value;
apparently I can't reference a form object like this. What is the correct way of going about it?
how to get a js variable later in the html......My page is here: [URL]I want to access the 'selected' variable from the function in <head> later in the page, to complete a form:
<script language="JavaScript">
document.write('<INPUT TYPE="hidden" name="selected" value="'+selected+'">');
</script>
I have about 13 ul li a items in a list and some have nested lists within them e.g. ul li ul li a and some don't. I want to prevent the default action on only a elements that have nested lists within them but not prevent default action for ones that don't. Here's an example of the markup.
[Code]...
However, instead, is there a way to tell jQuery to only apply this preventDefault to ul li a elements that have ul li a descendants/children (not sure of correct terminology here) so I can have the list items in any order?
just wondering if there is any way for the :contains to not look in children to find something? Tried $(':contains("$")');, but it returns everything. Was thinking of something like $(":not(':parent')").filter(':contains("$")');, but the console returns null (and even then it would exclude elements that have children and their text includes "$".)
Trying to make a script that looks through a page and finds the price on any page. The only way I could think of doing this relatively accurately is to search for all elements with "$" in the text, then get the one that has the largest height/width (That's problem #2, I think -- will deal with it once i get there :)
I'm trying to get an unordered list and its children as an HTML string on a mouseout event, but html()only selects the child elements:var theHtml = $('ul', this).html();I've tried using andSelf(), but that doesn't return the result I want:var theHtml =$('ul',this).and Self(). html();I can't choose $(this).html() as I need only the list.
