通过键JavaScript从关联数组调用函数

Question

In JavaScript I have associative array of functions like this (like static field of a class):

functions={'name': function(){},'name':function(){}};

each function do something with array. I also have method:

this.doSomethind= function(name, array){//class member

I need to call one of the functions finding it by name.

$.each(functions, function(key, value) {
                 if(key == name)
                    //here I need to call function with array as paremeter. It seems value(array); doesn't work.
                        }); 
}

Sorry if it's a dumb question, I'm just new in JavaScript. Thanks

Answer 1

If I'm understanding your problem correctly, you should just be able to say:

functions[name](array);

Instead of the $.each() loop.

Answer 2

尝试这个：

value.apply(this, [array])

Answer 3

As far as the information you have provided, you cannot access a parameter that is not yet in scope from the class methods. in your example spelling corrected

  //'array' is undefined / out of scope
  this.doSomething = function(name,array){
    //array is defined / in scope!
   };

Otherwise if the variable array you are talking about is defined in the scope somewhere, the first answer will work.
