JQuery :: Can't Access Object Variable From Object Method

Mar 10, 2011

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?

Get The Object Value After Using GetElementById

Aug 25, 2006

I've built a table on the fly within a js function. In another function I'm trying to get the value of a cell in a particular row on that table. I've retrieved the cell object but cannot get it's value :

var claimDate = parent.expenseDisplay.document.getElementById("row"+lineNo+"Date");

now I thought that the following would give the the data
var cdate = getObject(claimDate).value;

JQuery :: Cannot Get Access To Object

Feb 7, 2011

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.

Need To Only Access Object On Demand

Jan 20, 2010

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.

Access An Embed Object Via Javascript

Jul 23, 2005

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=&#390;' width=&#390;'>

<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

How Do I Access The Object Instance From Within Class

Apr 22, 2007

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!

JQuery :: Access To Parent Object Within Each()?

Oct 11, 2010

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?

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?

JQuery :: Traversing - How To Access Object

May 6, 2010

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

Way To Access Object's Internal Properties

Apr 1, 2011

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;

Cannot Access Global Variable Inside Object Declaration

May 9, 2011

Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).

The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;

//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}

//this function is in an interval
function moveslides() {
/* this is where I have the problem

It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...
}}}
The page is at [URL] and works on every browser, including finnicky opera, except for ie. The full code is availabe when you right click and view the source on the page.
