php方法调用模式与函数调用模式简例

复制代码 代码如下:

var doubling=function(x){
return x*2;
};
var obj={
val:100,
};

复制代码 代码如下:

var obj={val:100,
prop:function(){
var that=this;
document.write('name: '+that+'; type: '+typeof(that)+'<br/>');
return doublling(that.val);
}(),
get_prop:function(){
var that=this;
document.write('name: '+that+'; type: '+typeof(that)+'<br/>');
return doublling(that.val);
},
};
