按特定字母对JS字符串数组进行排序

问题描述

我必须对这样的字符串数组进行排序:

I have to sort an array of strings like this:

var arr = ["akaw","waka","kawa","akwa"];

排序类型必须为特定字母，在这种情况下为W，因此我的函数必须返回此数组:

The type of sort must be by a specific letter, W in this case so my function must return this array:

arr = ["waka","kawa","akwa","akaw"];

这是一个动态数组，我不知道数组中的单词数，如果每个单词都没有字母W，一个W或某个W.

It's a dynamic array and I don't know the number of words in array and if each words have no letter W, one W or some W.

您知道一种用于执行此操作的排序功能吗?

Do you know a type of sort function to do that?

谢谢！

推荐答案

只需比较字母的索引即可.

Just compare the index of the letter.

arr.sort(function(a,b) {
    return a.indexOf("w") - b.indexOf("w");
})
