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是內範圍，和局部變量總是在內部範圍可見。

Answer 2

你試過了嗎？

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

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

closuserVariable是全局的readLocal，所以你可以訪問它。
