如何在Javascript中正确调用匿名函数？

Question

Here is my code:

var A = (function(){
    "use strict";

    function FetchJSON(){
        return someValue;
    }

    var Class = function(){
        // how do I correctly call FetchJSON() from inside this class definition?
    };

    return {
        Class: Class,
        fetchJson: FetchJSON
    };
})()

So basically I'm using JSLint to clean up my code and I'm just calling FetchJSON() from inside the Class object/function definition but JSLint is telling me I need to use the word 'new' before the FetchJSON() call and I'm thinking I don't. The code works with out the word 'new' just fine but JSLint is telling me it should have it. What's the deal?

Thanks

Answer 1

调用函数fetchJSON而不是FetchJSON，因此JSLint认为它不是构造函数。

Answer 2

按照约定，仅打算用作构造函数的函数（即带有new关键字）应以大写字母开头-有关更多详细信息，请参见此问题 。

Answer 3

It's because the first letter of FetchJSON is capitalized, causing JSLint to interpret it as a constructor. If you wish to keep it capitalized despite the warning, you may.
