收听状态和函数调用 [英] Listen to state and function invocations

问题描述

是否可以监听任何函数调用或状态更改

我有一个包装另一个的对象

 函数包装器（origiObj）{
 this.origObj = origObj; 
} 
 var obj = wrapper（document）; //这是一个例子
 var obj = wrapper（db）; //这是一个例子
  
 
时p>我想听听...... 
解决方案
是的，有可能：
函数很简单，属性必须被监视
  function FlyingObject（obj）{
 this.obj = obj; 
 for（var p in obj）{
 if（typeof obj [p] =='function'）{
 console.log（p）; 
 this [p] = function（）{
 console.log（orig func）; 
}; 
} else {
 this.watch（p，function（）{
 console.log（orig property）; 
}）; 
} 
} 
} 
 var obj = {
f：function（a，b）{return a + b}，
m：1 
}; 
 var fo = new FlyingObject（obj）; 
 
 
 fo.m = 5; 
 
 fo.f（1,4）; 
  
如果您的browser / node.js不支持Object.watch，请查看：
 所有浏览器的Object.watch（）？ 
 
Is it possible to listen to any function invocation or state change

I have a object that wrap another
function wrapper(origiObj){
   this.origObj = origObj;
}
var obj = wrapper(document);//this is an example
var obj = wrapper(db);//this is an example
now everytime someone tries to invoke obj.innerHTML or obj.query(..)

I would like to listen to that..
解决方案
Yes, it's possible:
functions are easy, and properties has to be watched
function FlyingObject(obj){
    this.obj = obj;
    for(var p in obj){
        if(typeof obj[p] == 'function'){
            console.log(p);
            this[p] = function(){
                console.log("orig func");
            };
        }else{
            this.watch(p,function(){
                console.log("orig property");
            });
        }
    }
}
var obj = {
    f:function(a,b){ return a+b},
    m:1
};
var fo = new FlyingObject(obj);


fo.m = 5;

fo.f(1,4);
If your browser/node.js doesn't support Object.watch, check this out:
Object.watch() for all browsers?
