Assume a form with a button
<form id="myform"
<input id="mybutton" type="button">
</form>
how can i use getElementById to access the button?
I tried this: var a
a=document.getElementById("mybutton")
but i get an error "a is not an object"
Any idea?
I use this code in basic:
document.getElementById("someID").innerHTML = 'someHTML';
But i want to use jQuery to detect the ID. like this:
$('#someID').innerHTML = 'someHTML';
But this is not working
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'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;
This code generates an "objected expected" error when I select the unselected option in the list.
Code:
<html><head>
<script type="text/javascript">
[code]....
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 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 have a html file with javascipt embeded in, in this file I want to use a table object in another javascript file. How do I access this object?

I'm just not sure what object they are talking about. This piece of code basically goes through and assigns x amount of divs a background image.
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 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?

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 Replies View RelatedIf "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.

MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve

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>

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 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;

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've created an object and within this object, I've added an eventlistener. But the problem now is that after addEventListener is being called to access a callback function, the callback function is not able to access the properties within its own class. Code:

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.

From a JS object containig contextReady. The problem is that this within the OnSuccess is not the class but something else (e.g. a window).How can I update the right this.contextReady?
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) {
