【记录】这样在网页里构造JS 更加容易理解

Object.extend = function(destination, source) {
for (var property in source) {
                destination[property] = source[property];
            }
return destination;
    }


var Class = {
          create: function() {
return function() {
this.initialize.apply(this, arguments);
            }
          }
    }


var aa=Class.create();
    aa.prototype={

        initialize:function(options){
this.SetOptions(options);
            },

        SetOptions: function(options) {

this.options = {//默认值
                xxx:    0,//最小值
            };

            Object.extend(this.options, options || {});
          },

        show:function(){
                alert(this.options.xxx)
            }
      }


var cc=new aa({xxx:100})
  cc.show();
