var myarry = [
{name: 'liuyang',age :13},
{name:'jike',age:15},
{name:'liuyang',age:223 },
{name:'jike',age:42},
{name:'ligongjiu',age:22} ]
// 传入数组(表格的table)和表格的key如name
function 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)
结果：
[ { name: 'liuyang', age: 13 },
{ name: 'jike', age: 15 },
{ name: 'ligongjiu', age: 22 } ]
