Dynamic function name in javascript?

I want to achieve the below result .Can someone tell me how.Basically name is dynamic.

 var name = 'tab'+ ID; 
name(tab);

So far tried stuff which works fine.Is it a good way of doing or else somebody can suggest another way.

var function_name = 't'+ ID; 
if (typeof(window[function_name]) === "function")
{
 window[function_name](tab);
}

• alexp: Note that the above only works if the function being called is in the global scope, or if you explicitly put it there.

I'd first create an object to store your functions:

var funcs = {};

Then you can just use bracket notation:

var id = '001';
funcs['tab'+ id] = function(tab) {
};
funcs.tab001(tab);
// or if you have special chars...
funcs['tab001'](tab);
