您还可以创建一个动态排序函数，根据您传递的值对对象进行排序：
function dynamicSort(property) {
var sortOrder = 1;
if(property[0] === "-") {
sortOrder = -1;
property = property.substr(1);
}
return function (a,b) {
/* next line works with strings and numbers,
* and you may want to customize it to your needs
*/
var result = (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
return result * sortOrder;
}
}
因此你可以拥有如下对象数组：
var People = [
{Name: "Name", Surname: "Surname"},
{Name:"AAA", Surname:"ZZZ"},
{Name: "Name", Surname: "AAA"}
];
...当你这样做时它就会起作用：
People.sort(dynamicSort("Name"));
People.sort(dynamicSort("Surname"));
People.sort(dynamicSort("-Surname"));
其实这已经回答了这个问题。下面部分是因为很多人联系我，抱怨它 不适用于多个参数 .
多个参数
您可以使用下面的函数来生成具有多个排序参数的排序函数。
function dynamicSortMultiple() {
/*
* save the arguments object as it will be overwritten
* note that arguments object is an array-like object
* consisting of the names of the properties to sort by
*/
var props = arguments;
return function (obj1, obj2) {
var i = 0, result = 0, numberOfProperties = props.length;
/* try getting a different result from 0 (equal)
* as long as we have extra properties to compare
*/
while(result === 0 && i < numberOfProperties) {
result = dynamicSort(props[i])(obj1, obj2);
i++;
}
return result;
}
}
这将使你能够做这样的事情：
People.sort(dynamicSortMultiple("Name", "-Surname"));
子类化数组
对于我们这些幸运的人来说，可以使用 ES6，它允许扩展本机对象：
class MyArray extends Array {
sortBy(...args) {
return this.sort(dynamicSortMultiple(...args));
}
}
这将实现这一点：
MyArray.from(People).sortBy("Name", "-Surname");
