如何從閉包中的函數內部訪問閉包中的變量？

Question

例如：

var closure = (function(){
 var closureVariable = "Localized";

 function ReadLocal(){
  //how can I access closureVariable here?
 }
})();

Answer 1

只需使用closureVariable 。

例如：

var closure = (function(){
 var closureVariable = "Localized";

 function ReadLocal(){
  console.log(closureVariable);
 }
})();

ReadLocal是內部作用域，局部變量在內部作用域中始終可見。

Answer 2

你有嘗試過嗎？

var closure = (function(){
 var closureVariable = "Localized";

 function ReadLocal(){
  //how can I access closureVariable here?
   console.log(closureVariable);
 }
})();

closuserVariable對於readLocal是全局的，因此您可以對其進行訪問。
