Instead of the usual syntax...
The problem is that it's hard for me to adapt procedures which I'm used to within the normal syntax for the literal notation. E.g:
Is this variable global or local? If it's local, how do I declare a variable globally? I also wonder if it is possible to bind events to objects from within the object? And if I'm correct - jQuery is coded this way, but how can they then make use of their selector:
When it is an object defined with literal notation that doesn't have a constructor?
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".
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();
code below the function set() to the keyup event for the class "Labels". the function checks to to see if the key pressed was chr(13), if it is not, MyIndex called, and this all works fine. When a chr(13) is detected the function set(this) is called.Inside function set(this) I need to get the name of the object's parent name, but can't figure it out.[code]
I have a setup where I need to get the function calling a function, which works fine, I just use arguments.callee.caller.Now I need to take it a step further and get the object that the function belongs too. For example in a onclick="parentObj.someFunction()" parentObj.someFunction calls some other function. I need a way to know that parentObj was involved, just getting someFunction isn't enough because parentObj has properties that are used in someFunction. To make it more interesting lets say I can't pass any more parameters to someFunction, so I can't pass parentObj into it as an argument.
I have an object, "A", which contains another object "B", as an attribute.
How do I get a hold of Object "A" from within "B"? i.e. I need to refer to the object that B is stored inside from within B's code. Is there some superclass equivalent of 'this' that I don't know about? ('parent'?!)
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 am developing a web application with full of independent widgets in form of iframes. I would like to avoid embeding jquery (and jQuery UI) in each iframe's head to reduce number of requests and want to use the libs from the parent window instead. In iframes' head I tried the following code:
Well it works but naturally as the jquery object belongs to the parent document I can manipulate only the DOM nodes of parent document from the iframe and not the DOM nodes of the iframe itself! I think if I could replace the "document" object of "window.$" with iframe's "document" object it would work!
1) Is "=" copy by value or by reference? If I succeed to replace the "document" object in "window.$", will it be also replaced in "window.content.$"?
"Add element" | "Delete element"
if u click on the add element, then it adds an element, and if u click on the delete element, then it deletes the added element.

integrating PHP-HTML-JS I'd need some help for doing the following:I have a index.php including:
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.
