进行原型制作时跟踪javascript对象引用的最佳方法是什么

Question

what's best practice when it comes to keeping track of an object reference in javascript:

function class1(param) {
this.param = param;
self = this;
}

class1.prototype.method1 = function () {
console.log(self.param);
}

$('document').ready(function () {
   object1 = new class1('foo');
   object2 = new class1('bar');
   object1.method1(); // expected: foo , actual: bar 
   })

Currently self appears to be global and is overridden in the constructor of object2. I'd be very grateful if someone could offer some advice.

Answer 1

You don't need to keep track, just use this like so:

function class1(param) {
this.param = param;
}

class1.prototype.method1 = function () {
console.log(this.param);
}

Answer 2

function class1(param) {
    this.param = param;
}

class1.prototype.method1 = function () {
    console.log(this.param);
}

$('document').ready(function () {
   var object1 = new class1('foo');
   var object2 = new class1('bar');
   object1.method1(); // expected: foo , actual: foo 
});

Why you want to add this self thing?
