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是内部作用域，局部变量在内部作用域中始终可见。

Answer 2

你有尝试过吗？

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

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

closuserVariable对于readLocal是全局的，因此您可以对其进行访问。
