js裡的表格數組某個key去重

標籤：turn   ==   reac   console   class   name   push   tin   com   

如Elemgnt的table繫結資料要某個key是唯一的

var myarry = [     {name: ‘liuyang‘,age :13},     {name:‘jike‘,age:15},    {name:‘liuyang‘,age:223 },    {name:‘jike‘,age:42},    {name:‘ligongjiu‘,age:22} ]// 傳入數組(表格的table)和表格的key如namefunction deweight (arr, key) {    let ret = []    arr.forEach((item, index, self) => {        let compare = []        ret.forEach((retitem, retindex, retself) => {        compare.push(retitem[key])        })        if (compare.indexOf(item[key]) === -1) {        ret.push(item)        }    })    return ret}var result = deweight(myarry,‘name‘)console.log(result)

　　

結果:

[ { name: ‘liuyang‘, age: 13 },
{ name: ‘jike‘, age: 15 },
{ name: ‘ligongjiu‘, age: 22 } ]
