re: JavaScript, 5 ways to call a function

@Alexey, I did override the entire prototype but in this case the prototype was empty and I had no use for the constructor property. I was only trying to explain how constructors behave.

But you're right, the way you suggested is recommended over what I showed.

Thanks.

Is this really what you wanted to do?

// declaring instance methods

ArrayMaker.prototype = {

someMethod: function () {

alert( 'someMethod called');

getArray: function () {

return this.theArray;

}

};

In this way you've overridden the ArrayMaker.prototype that was created by JS when you created ArrayMaker function. The (possibly) unwanted effect of it is that Array.Maker.prototype has lost the constructor property that was pointing at the ArrayMaker function.

Wouldn't the code below be better to preserve the OO style?

ArrayMaker.prototype.someMethod = function () {

alert( 'someMethod called');

}

ArrayMaker.prototype.getArray = function () {

return this.theArray;

}

...something I almost forgotted: all javascript libraries nowadays use self-invoking anonymous functions which I find way beyond the programming standards of other languages.

I simply prefer the construction of an empty object and everything added upon it afterwards:

//construct a global Function object

function MYLIB(){}

//a built-in type as property

MYLIB.property1="abc"

//an object as property

MYLIB.property2=new Prop2_constructor();

//function

MYLIB.a_function1 = function(arg1, arg2){

//...some code

}

...

@Cedik, the construct you are asking about is commonly called "self-invoking anonymous function". It's basically a cuntion declaration that gets called right after it's declared (the parenthesis at the end are calling the function). The function need to be wrapped in parenthesis because some browsers don't like if do simply: function(){ /* something */ }();

@kumar, the btn var does end the process with a reference to the last button, that's not a problem here. The problem is the value of "i", it also contains the last value form the loop, and a reference to "i" is kept inside the event handler function and displayed in the alert message when that function gets invoked.

did not understand why do not the var btn refer to the last button object. why are multiple btn variables getting created?? i thought the btn would refer to the last button object!!

I followed steps given in the blog post here and no theme is apilepd just like that. I guess you missed to talk about JQuery binding like below, because my page works after adding below binding on document ready event in a JS file $(function() {$( input:submit, a, button , .demo ).button();$( a , .demo ).click(function() { return false; });});I may be wrong, however prefer to get it clarified by you once. Thanks!
