JavaScript的排序功能。排序第一，而第二位 [英] Javascript sort function. Sort by First then by Second

问题描述

我有对象sort.Each对象的数组有两个参数：强度和名称

I have an array of objects to sort.Each object has two parameters: Strength and Name

objects = []
object[0] = {strength: 3, name: "Leo"}
object[1] = {strength: 3, name: "Mike"}

我想首先强度，然后按字母顺序进行排序。我使用下面的code。通过第一个参数排序。我如何排序，然后由第二？

I want to sort first by Strength and then alphabetically. I am using the following code to sort by the first parameter. How do I sort then by the second?

function sortF(ob1,ob2) {
  if (ob1.strength > ob2.strength) {return 1}
  else if (ob1.strength < ob2.strength){return -1}
  return 0;
};

感谢您的帮助。

Thanks for your help.

推荐答案

展开您的排序功能是这样的;

Expand your sort function to be like this;

function sortF(ob1,ob2) {
    if (ob1.strength > ob2.strength) {
        return 1;
    } else if (obj1.strength < obj2.strength) { 
        return -1;
    }

    // Else go to the 2nd item
    if (ob1.name < ob2.name) { 
        return -1;
    } else if (ob1.name > ob2.name) {
        return 1
    } else { // nothing to split them
        return 0;
    }
}
