Question

I have a function in JavaScript:

function alertMe($a)
{
   alert($a);
}

Which I can execute like this: alertMe("Hello");

I want to do is assign alertMe("Hello") with the "Hello" parameter to a variable $func, and be able to execute this later by doing something like $func();.

I would like to add the comment as answer

Code

//define the function
function alertMe(a) {
    //return the wrapped function
    return function () {
        alert(a);
    }
}
//declare the variable
var z = alertMe("Hello");
//invoke now
z();
