js对json数组进行排序
废话不多说，直接上代码
// 升序排列 function up(a, b) { return a.val-b.val }, // 降序排列 function down(a, b) { return b.val-a.val }, // sort 会直接对原数据排序 testJson.sort(up)例如：
let test=[{"val":100},{"val":70},{"val":50},{"val":20},{"val":10}] test=test.sort(up)js根据json数组多个字段排序
let newArray = [ {product: "1", matno: "420200011480006",salebillno:"xsdd2733-8", sales: "800"}, {product: "2", matno: "420200011480007",salebillno:"xsdd2733-2", sales: "300"}, {product: "3", matno: "420200011480006",salebillno:"xsdd2733-5", sales: "100"}, {product: "4", matno: "420200011480006",salebillno:"xsdd2733-3", sales: "200"}, {product: "5", matno: "420200011480008",salebillno:"xsdd2738", sales: "600"}, {product: "6", matno: "420200011480010",salebillno:"xsdd2734", sales: "400"}, {product: "7", matno: "420200011480009",salebillno:"xsdd2735", sales: "700"}, {product: "8", matno: "420200011480001",salebillno:"xsdd2737", sales: "500"} ] /**数组根据数组对象中的某个属性值进行排序的方法 * 使用例子：newArray.sort(sortByArr(['matno'],true)) //表示根据matno属性降序排列;若第二个参数不传递，默认表示升序排序 * @param attr 排序的属性 ['matno','salebillno'...],根据一个字段或者多个字段排序 * @param rev true表示升序排列，false降序排序 * */ function sortByArr(arr, rev) { if (rev == undefined) { rev = 1; } else { rev = (rev) ? 1 : -1; } return function(a, b) { for (var i = 0; i b[attr]) { return rev * 1; } else { return rev * -1; } } } } } /**升序**/ newArray.sort(sortByArr(['matno','salebillno'],true)) [{product: '8', matno: '420200011480001', salebillno: 'xsdd2737', sales: '500'} {product: '4', matno: '420200011480006', salebillno: 'xsdd2733-3', sales: '200'} {product: '3', matno: '420200011480006', salebillno: 'xsdd2733-5', sales: '100'} {product: '1', matno: '420200011480006', salebillno: 'xsdd2733-8', sales: '800'} {product: '2', matno: '420200011480007', salebillno: 'xsdd2733-2', sales: '300'} {product: '5', matno: '420200011480008', salebillno: 'xsdd2738', sales: '600'} {product: '7', matno: '420200011480009', salebillno: 'xsdd2735', sales: '700'} {product: '6', matno: '420200011480010', salebillno: 'xsdd2734', sales: '400'}] /**降序**/ newArray.sort(sortByArr(['matno'],false)) // 输出 [{product: '6', matno: '420200011480010', salebillno: 'xsdd2734', sales: '400'} {product: '7', matno: '420200011480009', salebillno: 'xsdd2735', sales: '700'} {product: '5', matno: '420200011480008', salebillno: 'xsdd2738', sales: '600'} {product: '2', matno: '420200011480007', salebillno: 'xsdd2733-2', sales: '300'} {product: '1', matno: '420200011480006', salebillno: 'xsdd2733-8', sales: '800'} {product: '3', matno: '420200011480006', salebillno: 'xsdd2733-5', sales: '100'} {product: '4', matno: '420200011480006', salebillno: 'xsdd2733-3', sales: '200'} {product: '8', matno: '420200011480001', salebillno: 'xsdd2737', sales: '500'}] 总结
