javascript - 如何从闭包中的函数内部访问闭包中的变量？

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是一个内部作用域，局部变量在内部作用域中总是可见的。

Answer 2

你试过这个吗？

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

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

closuserVariable 对 readLocal 来说是全局的，所以你可以访问它。
