如何从数组对象中获取多个匹配的值？

我的情景是：

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filter()，如下所示：

＆＃13;

＆＃13;

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);

＆＃13;

＆＃13;

＆＃13;

Answer 2

在student阵列上使用过滤器：

＆＃13;

＆＃13;

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)

＆＃13;

＆＃13;
