在骨干字母数字排序的集合 [英] Sort a collection alphanumerically in backbone

问题描述

我写了一个比较的基础上身份证这样的集合进行排序：

I have written a comparator to sort the collection based on "id" like this:

comparator: function(coll) {
    return coll.get('id');
}

该输入工作得很好：ID-1，ID-0，ID-2，ID-199进行排序为ID-0，ID-1，ID-2，ID-199

This works fine for input: "id-1, id-0, id-2, id-199" to sort as "id-0, id-1, id-2, id-199"

但不排序数字在这里：ID-1，ID-0，ID-2，ID-199，ID-99作为ID-0，ID-1，ID-2，ID-199，ID -99 - ID-99应该是ID-199之前

But does not sort numerically here: "id-1, id-0, id-2, id-199, id-99" as "id-0, id-1, id-2, id-199, id-99" -- id-99 should be before id-199.

推荐答案

作为评论由@suish这是解决的方法是通过执行替换所有非数字部分空字符串。

As commented by @suish the way this was solved was by performing a replace of all non-numerical part with empty string.

coll.get('id').replace(/[^0-9^\.]/g,"")|0 –
