如何从数组对象获取多个匹配值？

我的情况是：

var studentData = [
                 {name:"Ram",htno:1245},
                 {name:"mohan",htno:1246},
                 {name:"madhu",htno:1247},
                 {name:"ranga",htno:1248}
              ];

var studentsToCompare = ["mohan","ranga"];


Expected output:
var matchedStudentsdata = [
                 {name:"mohan",htno:1246},
                 {name:"ranga",htno:1248}
              ];

Answer 1

尝试使用filter() ，如下所示：

 var student = [{name:"Ram",htno:1245},{name:"mohan",htno:1246},{name:"madhu",htno:1247},{name:"ranga",htno:1248}] var matchedvalues = ["mohan","ranga"]; var matchedStudentsdata = student.filter(stu => matchedvalues.includes(stu.name)); console.log(matchedStudentsdata); 

Answer 2

在student数组上使用过滤器：

 var student = [{name:"Ram",htno:1245},{name:"mohan",htno:1246},{name:"madhu",htno:1247},{name:"ranga",htno:1248}] var matchedvalues = ["mohan","ranga"]; var matchedStudentsdata = student.filter(function(stu) { return matchedvalues.indexOf(stu.name) > -1; }) console.log(matchedStudentsdata)
