Question

i have a object in javascript and some already defined functions. but how can i assign those functions to the object attributes. i tried different ways. but no hope.. the snippet is given below

// object
var func = {
 a : '',
 b : ''
};

// methods
var test1 = function(i) { console.log(i); }
var test2 = function(i) { console.log(i*100); }

i need to assign the test1 to a and test2 to b. i tried like this.

var func = {
 a : test1(i),
 b : test2(i)
};

obviously the errors i not defined is throwing.. is ther any solution other than the below give sinppet.

var func = {
 a : function(i) { test1(i); },
 b : function(i) { test2(i); }
};

This does what you’re asking:

var test1 = function(i) { console.log(i); }
var test2 = function(i) { console.log(i*100); }
var func = {
  a: test1,
  b: test2
}

But isn’t very good style.

This might be better:

function exampleClass () {}
exampleClass.prototype.a = function(i) { console.log(i); };
exampleClass.prototype.b = function(i) { console.log(i*100); };

var exampleObject = new exampleClass();
