对象键值在数组中时如何过滤数组

你可以做到这一点

Array.prototype.filter()

var data = { records : [{ "empid": 1, "fname": "X", "lname": "Y" }, { "empid": 2, "fname": "A", "lname": "Y" }, { "empid": 3, "fname": "B", "lname": "Y" }, { "empid": 4, "fname": "C", "lname": "Y" }, { "empid": 5, "fname": "C", "lname": "Y" }] }var empIds = [1,4,5]var filteredArray = data.records.filter(function(itm){  return empIds.indexOf(itm.empid) > -1;});filteredArray = { records : filteredArray };
