===

A hooks to any Javascript function.

##Notice

```

[bool]hook:params{

	realFunc[String|must]:用于保存原始函数的函数名称,用于unHook;

	hookFunc[Function|must]:替换的hook函数;

	context[Object|opt]:目标函数所在对象,用于hook非window对象下的函数，如String.protype.slice,carInstance1

	methodName[String|opt]:匿名函数需显式传入目标函数名eg:this.Begin = function(){....};

}

[bool]unhook:params{

	realFunc[String|must]:用于保存原始函数的函数名称,用于unHook;

	funcName[String|must]:被Hook的函数名称

	context[Object|opt]:目标函数所在对象,用于hook非window对象下的函数，如String.protype.slice,carInstance1

}

```

##Examples

```

var myHook = new Hooks();

myHook.initEnv();

//普通全局函数

var _alert = null;

function myalert(param){console.log("before hook");}

alert.hook("_alert",myalert);

alert.unhook("_alert","alert");

alert(1);

//自定义对象匿名函数

function Person() {

this.getName = function(name) {

alert('Call' + name);

}

} 

var p = new Person();

var _p_getName = null;

function mygetName(name){alert("Hooked");}

p.getName.hook("_p_getName",mygetName,p,"getName");

p.getName.unhook("_p_getName","getName",p);

p.getName("pnig0s");

//原型对象函数

var _slice = null;

function myslice(param){alert("Hooked");}

String.prototype.slice.hook("_slice",myslice,String.prototype);

String.prototype.slice.unhook("_slice","slice",String.prototype);

var str = "pnig0s";

str.slice(1);

myHooks.cleanEnv(); //clear hooks

```
