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);

    CORS: credentials mode is 'include'

    XMLHttpRequest cannot load http://localhost/Foo.API/token. The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:5000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
