lodash 利用_.find数组去重

2020-02-18 13:20:32

去重逻辑主要是讲一个数组的内容重新拿出来进行遍历属性不同的元素加入到数组中( .find每次都会检查属性相同的元素)

var _ = require("lodash")

var results = [

{ id: 1,

test: '测试1',

{ id: 2,

test: '测试2',

{ id: 3,

test: '测试3',

{ id: 3,

test: '测试4',

}

];

console.log(results.length);

var data = [];

for (var i = 0; i < results.length; i++) {

console.log(results[i]);

var row = results[i];

var bill = _.find(data, function(o) {

return row.id == o.id

})

if (!bill) {

data.push(row);

}else{

存在重复元素

}

console.log(data);
