JS 对象数组Array 根据对象object key的值排序sort
JS 对象数组Array 根据对象object key的值排序sort有个js对象数组 var ary=[{id:1,name:"b"},{id:2,name:"b"}] 需求是根据name 或者 id的值来排序
函数定义:function keysrt(key,desc) {
return function(a,b){
return desc ? ~~(a < b) : ~~(a > b);
}
}
使用:var ary=[{id:1,name:"b"},{id:2,name:"b"}];
ary.sort(keysrt('name',true));
ary.sort(keysrt('name',false));
ary.sort(keysrt('id',false));

function KeySort(key,desc) { // KEY：需要排序的键名 desc：排序类型 true是从大到小 false是反之
return function(a,b){
return desc ? ~~(a < b) : ~~(a > b);
}
}
function paixu(key,desc) {
DemoData.sort(KeySort(key,desc));// 排序处理
// 输出排序后的结果
var $text = "";
$.each(DemoData, function (key, value) {
var $div = "<div>";
$.each(value, function (key, value) {
$div += "<span>" + key + "：" + value + "</span>" + " ";
});
$div += "</div>";
$text = $text + $div;
})
$text += "";

附加：两个对象数组，某一项永远置顶并且排序，Code：<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="utf-8" />
<title>demo</title>
<style type="text/css">
.aa{background: #ccc;}
</style>

<body>
<div id="element"></div>
<button onclick="paixu('name',0)">name 正序</button>
<button onclick="paixu('name',1)">name 倒序</button>
<button onclick="paixu('age',0)">age 正序</button>
<button onclick="paixu('age',1)">age 倒序</button>
<button onclick="paixu('time',0)">time 正序</button>
<button onclick="paixu('time',1)">time 倒序</button>
