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是内范围，和局部变量总是在内部范围可见。

Answer 2

你试过了吗？

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

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

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