JavaScript调用名称为匿名作用域中的函数的字符串形式的函数

Question

Is this doable in javascript ? I try to call the function who's name is in the variable named "name" (sorry!). That function is not in the global scope.

(function () {
    var myFunc, name;

    myFunc = function(){
        alert("Hi!");
    };
    name = "myFunc";
    //myFunc();  // work

    (name)();   // do not work
    this[name]();   // do not work

})();

Note: I have a jsfiddle entry here

Answer 1

There is not an object for the "local scope" like there is for the global scope. You can (and should) make your own object to hold your functions:

(function () {
    var name = "myFunc";

    var funcs = {
        myFunc: function(){
            alert("Hi!");
        }
    };

    funcs[name]();
})();

Answer 2

eval(name)();

eval is not always evil. It does have its uses.

If you really don't like eval, try storing your variables in an object instead:

(function () {
    var vars = {};

    vars.myFunc = function(){
        alert("Hi!");
    };

    vars.name = "myFunc";
    //vars.myFunc();  // work

    vars[vars.name]();    
})();

Answer 3

Change

myFunc = function(){

to

this.myFunc = function(){

then this will work:

this[name]();
