在JavaScript中定义固定的排序顺序 [英] Define fixed sort order in JavaScript

问题描述

我在研究中没有发现任何东西，因此我认为有人可以在这里为我提供帮助.

I haven't found something in my research so I thought someone can help me here.

我的问题是我想对包含状态的对象数组进行排序:

My problem is that I want to sort an array of objects which contains a status:

{
    "data":[
        {
            "status":"NEW"
        },
        {
            "status":"PREP"
        },
        {
            "status":"CLOS"
        },
        {
            "status":"END"
        },
        {
            "status":"ERR"
        },
        {
            "status":"PAUS"
        }
    ]
}

现在，我想设置一个固定的排序顺序，例如所有状态为"END"的对象首先出现，然后是状态为"PREP"的所有对象，依此类推.

Now I want to set a fixed sort order like all objects with the status "END" coming first then all objects with the status "PREP" and so on.

有没有办法用JavaScript做到这一点?

Is there a way to do that in JavaScript?

先谢谢您了:)

推荐答案

这是使用标准.sort()回调的非常简单的比较操作:

It's a pretty simple comparison operation using a standard .sort() callback:

var preferredOrder = ['END', 'ERR', ..];
myArray.sort(function (a, b) {
    return preferredOrder.indexOf(a.status) - preferredOrder.indexOf(b.status);
});
