【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();

运行以上代码

  
Object.extend = function(destination, source) {
            for (var property in source) {
                destination[property] = source[property];
            }
        return destination;
    }
  
  
  
  var bb=function(o){
          this.options={xxx:0};
        Object.extend(this.options, o || {});
      }
  
  bb.prototype={
          show:function(){
                alert(this.options.xxx)
            }
      }
  
  var dd=new bb({xxx:100})
  dd.show()
