JavaScript - 从匿名函数返回(varScope) [英] JavaScript - Return from anonymous function (varScope)

问题描述

<script>
    var sample = function() {
        (function() {
            return "something"
        })();
        // how can I return it here again?
    }
</script>

有没有办法再次从父函数中的匿名函数返回返回值，或者我是否需要使用定义的函数来获取返回值?谢谢！:)

Is there a way to return the returned value from the anonymous function in the parent function again or do I need to use a defined function to get the returned value? Thanks! :)

推荐答案

只需将 return 语句放在调用函数的位置即可.

Just put the return statement at the point where you call the function.

<script>
    var sample = function() {
        return (function() {  // The function returns when you call it
            return "something"
        })();
    }
</script>
