Question

Currently i’m working on a jquery plugin and looking at other plugin code i found a common way to write it passing throught an object, somethng like :

$.fn.myplugin = function(method){
    //... some code
    object = new $.myobject(param);
    //... other code

    // myobject definition
    $.myobject = function(param){
        //.... my object code
    }
} 

I can’t understand how works $.myobject definition and why many developers use it to define their plugins.

Could you give some info and tutorial/links to documentation if possibile ?

Answer 1

The ability to add properties at runtime to javascript objects is what makes every javascript object an ‘expando’ object.

There is an explanation here
