javascript数组排序函数

  1. 代码:
    /*
    @desc:表格排序类
    @param data 待排序数组
    */
    function tablesort(data){
    this.data = data
    this.sortby = true
    /*
     @desc:主方法,排序
     @param item 排序字段
     @return ret 排序后的数据
     */
    this.sort = function(item){
        if(this.sortby){
            var ret = this.data.sort(function(a,b){
                return a[item]>b[item]
            })
        }else{
            var ret = this.data.sort(function(a,b){
                return a[item]
  2. 测试:
    var data = new Array(
     {
         id:1,
         title:'title1',
         content:'content1'
     },
     {
         id:3,
         title:'title2',
         content:'content3'
     },
     {
         id:2,
         title:'title3',
         content:'content2'
     }
    )
    var tablesort = new tablesort(data)
    var ret = tablesort.sort('id')
    console.log(ret)
    var ret = tablesort.sort('title')
    console.log(ret)
    var ret = tablesort.sort('id')
    console.log(ret)
  3. 输出:
    [ { id: 1, title: 'title1', content: 'content1' },
    { id: 2, title: 'title3', content: 'content2' },
    { id: 3, title: 'title2', content: 'content3' } ]
    [ { id: 2, title: 'title3', content: 'content2' },
    { id: 3, title: 'title2', content: 'content3' },
    { id: 1, title: 'title1', content: 'content1' } ]
    [ { id: 1, title: 'title1', content: 'content1' },
    { id: 2, title: 'title3', content: 'content2' },
    { id: 3, title: 'title2', content: 'content3' } ]
