Question

我有以下内容：

$(function () {
    var list = ["/62","/15","/65","/62","/15","/08","/01","/65","/62","/65","/62","/15","/01"];
    $.unique(list);
    console.log(list);
});

输出结果为：

["/01", "/65", "/62", "/65", "/08", "/15"]

https://api.jquery.com/jquery.unique/说：

The $.unique() function searches through an array of objects, sorting the array, and removing any duplicate nodes.

两个“/ 65”是否被认为是不同的？如果是这样，为什么：

$(function () {
    var list = ["/62","/15","/65","/62","/15","/08","/01","/65","/62","/65","/62","/15","/01"];
    $.unique(list);
    $.unique(list);
    console.log(list);
});

产生

["/15", "/08", "/62", "/65", "/01"]

为什么以“/ 0”开头的那些不在输出的开头？

正如你可以从长评论帖中猜测的那样，使用$.unique是错误的。相反，请使用Underscore的_.uniq。

为什么JQuery` $ .unique（）`没有排序？
