I have this below code snippet
I have an object myscript and from within the method validate, i want to call the method init. so is there there anyway that I can call the method init without having to prefix like this: myscript.init();
I tried this.init(); but it's not working

This is the first time i'm really using javascript objects (well the first time i've written my own one) so the problem is probably a very simple one...
I've got this:
Code:
When i change the country from the dropdown box i get an error "hometown.setCities is not a function" but the thing is that i can call this in other ways eg from the address bar (javascript:hometown.setCities()) and it works perfectly.
I am trying to call a ActiveX object from JSP using the ActiveXObject method in javascript. I have a dll filed named Patchgenerator.dll which is registered and assigned a prog id "Patchgenerator.PatchGen.1" which is being passed as an argument to the ActiveXObject method. Below is the code i am trying to execute..
[Code]...
When i write the above code and save it as an html file it works fine..the activex object is created and the methods are called , but when i copy the same code to a file and save it as jsp file under webapps folder under tomcat it doesnt work and reports a javascript error with the error being: Automation server cant create the object at line : var SSOObj = new ActiveXObject("Patchgenerator.PatchGen.1");
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?
Below I declared a basic object literal with 2 methods. The
"doSomething" method is call from the "useDoSomething" method but the
call is only sucessful if I use the "this" keyword or qualify the call
with "SomeObj".
Can someone describe why this is happening?
var SomeObj = {
doSomething : function()
{
return 'Did something'
},
useDoSomething : function()
{
//Doesn't work - doSomething() no defined.
return doSomething();
//Works
//return this.doSomething();
//Works
//return SomeObj.doSomething();
}
}
alert(SomeObj.doSomething());
alert(SomeObj.useDoSomething());
I have read this from the interentfunction getArea(radius)
Imagine we want to create lots of circle objects using our object as a base - if we declare using the object literal, were not able to do that.
But the new operator can do that - basically allowing us to re-use a user-defined object.
can't understand on the above why we declare using the object literal not able to do that.
I am having a hard time getting the javascript file to run any of the functions after I've changed my original script to object literal format. Please tell me why it isn't working! I have attached a zip format of my code.

The problem is that in IE, when I call myfunc() it complains with the error: Class is undefined
I'm not sure what I'm doing wrong. Class is declared in as much global scope as possible, and that shouldn't even matter in JS.

In an attempt to answer another question in this group, I've had to resort
to calling the DOM method, Node.removeChild(), using a reference to it
(long story...). That is, passing Node.removeChild.
In Opera (7.23/Win), the call appears to do nothing - the node remains -
but no errors are shown. In Netscape (7.0/Win), an exception results[1].
On IE (6.0/Win), the node is removed.
Strangly, if I pass another function reference, say window.alert or a
user-defined function, there is no problem. This illustrates the problem: Code:
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;

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'm using the following code to refresh an iframe:

The problem is that Zenbox.show () gets called before the src attribute is fully loaded, so the refresh is visible to the user. Is there any way to setup a callback when the iframe.src is fully loaded that I can call Zenbox.show() in ?

what is the best way to setup one literal to be the prototype for another?So far I can only think of making a copy into a constructor.
Code JavaScript:
var meths = {
// creates a constructor function populated with a shallow copy of child
// the prototype for the new instance is set to the parent.

I'm having a lot of trouble understanding how to get my targeting working in IE. Let's say I have a <div id="test"> </div> with some form information in between. I use xmlhttpreq to process but I want the information after processing to appear inside the test div. I have it working perfectly with firefox but for the life of me I just can't get it to work with IE. I can only ouput to another DOM object.innerHTML and not the original.
View 6 Replies View RelatedTrying to figure out what was happening in a snippet in the jQuery docs. The snippet I refer to is here , documenting event objects.
The code:
Has me a tad confused. I know that e is an event object that calls keydown event for keycode 64 but what I am unsure of is how it is being triggered. There is no context to it, if you use .trigger() that way is the event called upon the loading of the object? If not when is .trigger() being called?

View 3 Replies View RelatedI'm working on a drag and drop HTML editor, in which blocks can be positioned. I need to build a controller which listens to mouse events and takes appropriate action (a state machine). The system is built using prototypes and objects. The Controller class looks like this (I removed some methods for simplification):
Code JavaScript:
/**
* Creates a controller for a document
*/
function Controller() {[code]....
The method 'handleMove' is entitled to handle a mouse move on the overlay. Because the 'this' keyword would not point to the Controller object I've written a wrapper according to the W3C EventListener interface (http://www.w3.org/TR/DOM-Level-2-Eve...-EventListener). This wrapper holds a reference to the object in which the method resides that's handling the event, so that the important 'document' attribute can be reached. This document holds the document that is being edited (it's of a custom type, and not to be confused with the document as in document.body)
The problem I now have is as follows. IE doesn't seem to be able to work with event handlers following the EventListener interface, but just functions. I need to get the object's reference there as well though, but this can't be done using an anonymous function, as at the moment it will be run it will be in a different scope, and not be able to reach the controller any more.Just using a global holding that reference variable, a method I used before, is not sufficient, as there may be multiple instances of the editor running on the same page.I have no problems in FFox, Opera, and Safari. Just IE because it uses an alternative event listener model.
