从javascript的闭包内部调用外部函数

Question

I have function defined as main which has a function inside say hit()

(function main(){

 var player1=new player();

 function hit(){
    //some code
 }
})();

This belongs to file main.js

I have another function player() in player.js which is called using the constructor at main.js

function player(){
   setTimeout(function(){ 
            hit(); //cannot call hit
        }, 1500);
}

I want to call the hit() function in main.js from player.js, but I cannot do so as I get a undefined error. Isn't main.js completely accessible from player.js due to closure property

The way I include this files is:

<script src='player.js'></script>
<script src='main.js'></script>

Thanks

Answer 1

hit won't be accessible outside the closure. If you want it to expose globally , you will have to do something like:

//get hold of the global object
var global= (function(){
    return this;
})();

(function main(){
     var player1=new player();
     global.hit= function(){
        //some code
     };
})();

This is what I did and it seem to work for me

var mainObj=new main();

function main(){

 var player1=new player();
 var this.hit=hit;

 function hit(){
      //some code
 }
}

function player(){
    mainObj.hit();
}
