I was try many way to do this but all unsuccessfull. I tried Ext.apply, Ext.extend, Ext.override but non of its work.
I tried

Ext.History.myFunc = function(){
    //do something
};

History is a singleton, so while it's possible to extend, it's probably easier not to. Can you put the helper methods onto some other static class?

[DTT_11-1983]

All i want to do is write some my own method for Ext.history but i don't want write it direct to ext-all-debug.js. What I have to do now ? I dont know why it work on FireFox but not in IE6.

[DTT_11-1983]

My problem exactly is how can I override function handleStateChange in history.js file

    function handleStateChange(token) {
        currentToken = token;
        Ext.History.fireEvent('change', token);
    } 

It's a private function.
Can anybody help me ?
Thanks

If you really have to, then just copy the source and make the appropriate changes.

Ext.apply should be what you want.

I've tried that method already but It still run the defaut function in ext-all-debug.js file. I can't make it run my function that I applied.

Paste the following in firebug, it works:

var mySingleton = function() {
    var priv1 = 'some private string';

    return {
        pubFn1 : function() {
            console.info('original pubfn1');
        },
        pubFn2 : function() {
            console.info('original pubfn2');
        }


    }


}();

Ext.apply(mySingleton, {

    pubFn1 : function() {
        console.info('NEW pubfn1 via override');
    }

});

mySingleton.pubFn1();a

I meant how do I override a private Function ? Your code work because pubFn1 is a public Function.

    function handleStateChange(token) {

        currentToken = token;

        Ext.History.fireEvent('change', token);

    } 

handleStateChange is a private function.

Like evant said, you can't unless you override the source from the file or make your own history obj:

var mySingleton = function() {
    var priv1 = 'some private string';
    function test() {
        console.info('this is a test');
    }
    return {
        pubFn1 : function() {
            console.info('original pubfn1');
            test();
        },
        pubFn2 : function() {
            console.info('original pubfn2');

        }


    }


}();

Ext.apply(mySingleton, {

    pubFn3 : function() {
        test()
    }

});

mySingleton.pubFn3();
