javascript數組排序函數

標籤：javascript數組排序函數

代碼：

/*@desc：表格排序類@param data 待排序數組*/function tablesort(data){this.data = datathis.sortby = true/* @desc：主方法，排序 @param item 排序欄位 @return ret 排序後的資料 */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]<b[item]        })    }    this.sortby = !this.sortby    return ret}}

測試：

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)

輸出：

[ { 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‘ } ]
