javascript数组排序函数
- 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]
- 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)
- 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' } ]
