Sorting Backbone collection alphabetically
提问by Will Hitchcock
Is there a way to do this out of the box with the _.sortBy method or any other part of the library?
有没有办法使用 _.sortBy 方法或库的任何其他部分开箱即用地执行此操作？
采纳答案by Hyman
Since you tagged your question with the backbone.js tag, I'm assuming you mean to sort a collection, you just need to provide a comparatorfunction on your collection and backbone will keep the collection sorted.
由于您使用backbone.js 标签标记了您的问题，我假设您的意思是对集合进行排序，您只需要在集合上提供一个比较器函数，主干将保持集合排序。
If your question is specifically alphabeticical sorting, I believe that is the default sort, from the backbone.js documentation (I linked to it above)
如果您的问题是专门按字母顺序排序，我相信这是来自backbone.js 文档的默认排序（我在上面链接到了它）
chapters.comparator = function(chapter) {
return chapter.get("page");
};

You mean like this?
你的意思是这样？
var array = [
{ name: "banana" },
{ name: "carrot" },
{ name: "apple" }
];
var sorted = _(array).sortBy("name");
I'd say it works out of the box.
我会说它开箱即用。
If you wanted to sort an ordinary array of strings, you probably just want to use sort:
如果您想对普通的字符串数组进行排序，您可能只想使用sort：
var flatArray = ["banana", "carrot", "apple"];
flatArray.sort();
See here. Also works.
见这里。也有效。
Note that Underscore's sortByreturns a newarray which is sorted, where JavaScript's built-in sortfunction sorts an array in place.
请注意，UnderscoresortBy返回一个已排序的新数组，JavaScript 的内置sort函数在其中对数组进行原地排序。
