what I want to do is clone the Object String and be able to use the clone. In essence what I'm looking to do:
var x = 'me';
String.prototype.returnMe=function(){return this;}
alert(x.returnMe(x)); // alerts: me
[code].....
I have a few String prototypes such as String.prototype.EscapeReg = function () { return this.replace(/[-[]{}()*+?.,\^$|#s]/g, "\$&"); }; // Escapes characters for use with a regular expressionI also have my own class/ library which is used like this var adg = new AndyG_ns.ADG_Utils(); adg.StartClock('AndyClock','dd mmm yy hh:nn'); // etc.What I would like to do is to only add the prototype to my library (not to the global namespace). The end result I'm looking for is to use code such as:
var adg = new AndyG_ns.ADG_Utils();
var myString = new adg.AString();
var parsed = myString.EscapeReg();
In addition, I want to be able to also use/create my special string sub-class within my library. I suppose I'm saying that I would like to extend or super-class the native String object.
The cloning of 2 elements WITH their events works untill we come into another event. Here is a part of the code:

How can I subclass a native class to get my own class with all the
function of the native clas, plus correct instanceof behaviour?
The scenario I'm thinking of is something like
function MyArray() {
Array.apply( this, arguments );
}
MyArray.prototype = new Array();
MyArray.prototype.constructor = MyArray;
var marr = new MyArray();
marr[0] = "abc";
marr.length == 1; // true
marr instanceof MyArray; // true
But this seems impossible due to the Array constructor returning a new
object even when called with my own "this" in the apply() above. Can
this be solved in any way?
I'd like to announce release 1.0.7 of JNEXT (JavaScript Native

by using JavaScript from within a Web Page. It is light weight, cross
platform, cross browser and designed with simplicity in mind....

I would like to do this WITHOUT jQuery.
I have tried to get an event listener to listen for when the user presses Control-D on their keyboard. This would trigger a confirm delete function - if you've ever used QuickBooks Ctrl-D is the command that does this and this is a financial application.
Problem is that in FireFox, Ctrl-D means bookmark the page and this window pops up. I want to "return false" before this happens.
On this subject I would also like to take over Ctrl-C and Ctrl-V eventually but with Ctrl-D it will work for anything. here is what I have. Again, IT WORKS, but doesn't stop the natural event (bookmark page) fromhappening:
Code:
function AddOnkeypressCommand(strCommand){
//---- version 1.0, by , last edit 2004-12-14
//add to array of commands:
m_onkeypressCmds[m_onkeypressCmds.length] = strCommand;
[Code].....
Am I the only person who finds wildly wrong the jQuery behavior of handler invocation for native events on state-changing elements like check boxes and radio boxes?Specifically, when the user clicks a check box or a radio box, the state of the element is changed and then the handler is invoked.However, when I call"click()" on the elements, the handler is invoked *before* the element value is updated. That makes it pointlessly difficult to write handler routines that need to look at the value to know what to do.

View 1 Replies View RelatedI was wondering if there are any sites dedicated to ending javascript objects using the prototype property to give them features like trimming string, removing elements of arrays by name, removing duplicates in arrays, etc. Granted I have functions to do this but there's probably a ton of other good ones out there. Most things I've seen are frameworks like JQuery (which is awesome) but it doesn't extend these objects.
View 2 Replies View RelatedThere's no native linked list implementation in JS. I'm wondering if it would be worth it to implement one.
I'm using a lot of insertions and deletions with arrays of around length 5. How fast are insertions and deletions in JS native arrays compared to an optimized (but not native) linked list implementation in this situation? How about arrays of length 10?

I am having problem with displaying data in fckeditor. I am opening clone dialogs that display forms from another page. Everything comes up fine but fckeditor is not displaying any data in it. This only happens on IE8, no issues on FF. If I view this page outside the jquery dialog everything works fine. So there is conflict between jquery dialog and fckeditor.
View 1 Replies View RelatedI'm a starter in using jQuery and I decided to work my way through the 'Learning JQuery' book from packt.Somewhere in Chapter 5 they use the clone() function with the false attribute. The JQuery version used in the book is 1.1.3a. With the clone(false) method the writer can clone only the matched element and not the descendants. And that works in 1.1.3a.I know that this is no longer the case in JQuery 1.4. Boolean is only for Event Handlers.But what is the new equivalent of this method? In other words. How can I clone an element with only the matched element and not it's descendants?
View 2 Replies View RelatedI have a block of HTML that I am cloning, as I want to manipulate it to remove an element, so that I can then append that new HTML somewhere else on the page.
[Code]....
Then in the jQuery, I have tried many different ways of removing stuff from that clone, but with no luck. E.g.
var cont = $('#container').clone();
$(cont).remove("copy_btn").appendTo("body");
There are no errors showing up in Firebug, but the html added to the bodu still contains the link with the id "copy_btn". Is this even possible? The api says that remove() will remove matched selectors from the DOM, so as this is just a set of elements is that the reason? If so, is there a way to achieve this, or would I have to append it somewhere on my page and then perform the manipulation?
I have a FORM with many elements, and some of them have names like "name1[]", "name2[]", etc..
I would like to create a button that, once clicked, will clone all the elements whose names end in "[]" (including labels, and select's options), giving them the same name (and possibly a different ID, but it's not important).
I am completely new to jQuery and almost new to javascript.
I came up with this code to clone the entire form:
<script type="text/javascript">
$(function(){
$('input.cloneMe').live('click',function(){
var f=$(this).closest('form').clone(true);
[Code]....
But how can i tell him to only clone the elements whose name ends in '[]' ?
i need to us instead of closest, but i really don't know what.
I have a form wich has a add/remove row button, this so the visitor can select multiple sets of data. All is fine and is being submitted via PHP.
Only problem is from number 10 and up, i am getting strange random numbers in the new rows that are added in their name. Like 1111 (instead of 11), 122222 (instead of 12). And because of this, every row from 10 and up won't be send through php, giving this random effect.
The full form can be viewed: [url]

I trying to figure out why CloneNode on an Iframe does not correctly clone the IFRAME with its contents and is there a workaround I can use to get pass this?. Basically what I am doing is dynamically building a table with Iframes inside it. The problem is I just want to build one Iframe because the contents of it can be very complex. After my Iframe is built I just want to clone the iframe as many times as I need later. I cannot use an HTML file and point the src of the Iframe to it. I have to put into the Iframe a very dynamic HTML document I get back form an Ajax call. This is truly the key of the problem. Since my pages can be complicated it can take around 2000ms to render. I don’t want to make each Iframe render every time when I already have the document ready to display. I just want to clone it very fast. I can not use the ‘scr’ of the iframe.
Here is a very simple example of my problem. Look near the end of the code to see the problem. Try this code and you can see the IFRAME does not Clone its contents. Is there any way around this problem? Please note that I also cannot use innerHTML to populate the cloned Iframe with my master Iframe’s contents. Because if I do this the page still takes 2000ms to render. I just want this thing to clone as it is. Code:
I am in need to drag and drop a image from a div to the form. But the original image should not be moved. It should remain in the same place. Only the clone of the image should be moved outside the div.
