JQuery :: How To Access True (This) Of Object
Jul 14, 2009
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 am using this Browser Plugin call: world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', ''); in the middle of my page, where I want to load this object. (It is a 3d rendering modul Viewpoint Player)
Now I want to add a browser check, as this plugin runs only in IE. When I dedect that the page is loaded with IE, I am writing via Jquery a class name into my body tag.
I thought, it would work if I do the following:
if($('body').attr('class').length > 1){
world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', '');
}
But for some reason, the if fails, as it seem that the plugin is called earlier than the jquery browser check, so the class name is not set at this point.
Then I thought, making a function arround and call it onLoad within the body tag.
Which has the disatvantage that the MTS Plugin is loading at the worng place on the page.
What I want, is that the call to the object "world = new MTSPlugin( '../obj/main.mtx', '100%', '100%', '', 'simple', '');"
is only at a trie condition at the place where it should be...

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?

I have searched the forums for a solution, however I cant seem to find one. Forgive me if there was and I couldnt find it. My problem is that every time I send my form, the script stops at the line xmlhttp.open("GET",url,true); and says access is denied. I know there are security issues, but I am using php to send the information to the script. The goal here is to scan the url for all the contents from google search. I am searching for a city, state and postal zip. That will give the according information. Here is my code:
var xmlhttp;
function getdata(){
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null){
[Code]....
This should solve the security issue but i am still getting the access denied error at the same line. I even tried redoing it all in javascript still no luck.

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'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?

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 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.

I want to access the features of a plugin without actually embedding
it into a page. Is this possible? Eg
The code to embed the object into a page is:
<OBJECT classid='CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5
codebase='http://www.test.com/plug.cab#version=3,1' "id='myPlugin'
height=Ɔ' width=Ɔ'>
<EMBED type='application/x-myPlugin' name='myPlugin' hidden='true'
src='in.txt'></EMBED>
</OBJECT>
I could simply add this using document.write, but for various reasons
I dont want to do this.
I would rather do something like:
var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-Web-Plugin"]) ?
navigator.mimeTypes["application/x-Web-Plugin"].enabledPlugin : 0;
myObj = new object("CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5");
myObj.pluginMethod

I have a javascript object which dynamically generates a table adding, deleting and moving rows as the user clicks on buttons or links. Problem is when I generate a table row and add the javascript method call to my class, I have to put the object instance name variable of the class in order for it to be called from the onclick=function(). This is seriously limiting, but I'm stuck for a way round it. Heres a edited of the code so you get the idea....
Instantiating the object :-
var dtl = new DynamicTableList("table1", $
{myObject.allFieldsAsJavaScriptArray}, true, true, true);
My javascript class DynamicTableList, note the dtl javascript object
instance variable being referred to in the addRow function. How can I
avoid this???
function DynamicTableList(thisObjName, tableName, options, showDelete,
showUp, showDown)
{
this.processRow = function(r, row, up, down)
{
...
};
this.processRows = function()
{
...
};
this.getVisibility = function(visible)
{
...
};
this.delRow = function(button)
{
...
};
this.addRow = function(selection)
{
...
if (showDelete)
{
var cell2 = document.createElement('TD');
var inp2 = document.createElement('IMG');
/
************************************************** ***********************************************/
inp2.onclick=function(){dtl.delRow(this);} // Have to specify
dtc!!!!!!!!
/
************************************************** ***********************************************/
inp2.title='Delete'
inp2.alt='Delete'
inp2.src='images/delete.gif'
cell2.appendChild(inp2);
row.appendChild(cell2);
}
...
tbody.appendChild(row);
this.processRows();
};
this.moveRow = function(node, vector)
{
};
}
Obviously the code dtl.delRow(this); is being dynamically generated, but how do I replace the dtl instance name with something that'll work whatever the user of this class calls the instance of it!

I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object.
In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element.
anyObj has 3 properties and one function increaseWidth()
increaseWidth() creates a new button with an onclick event handler and this is where I have a problem.
The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj.
The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me.
So is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function.
function anyObj(divObj){
this.elem = divObj;
this.width = 50;
this.height = 50;
[Code]....

I have a JS method register in a TD element as below:
Below is the Js Method:
The JS method works fine in IE but in mozilla throws an error that event is undefined.
I cant pass the event object from HTML while registering the method as HTML is written by someone else and I cannot change that. All I can change is the JS method.
How can i access the event object in JS method.

I have a page (page 1), my page 1 has an IFRAME which loads another page (page 2).
My page 2 has a JavaScript object declared on the page: var MyObject = new Object();
I want to access this object from the parent page (page 1).
I tried:
var TempObj = document.getElementById("MyIFrame");
TempObj.document.MyObject.value = "blah blah";
But it said MyObject didn't exist.
Can someone tell me how to access it in this manner?
