我正在使用angularjs过滤器，但一切正常，但是当我寻找一个薪水为30（仅作为示例）的人时，它不起作用，如果我再增加一个值，它就开始起作用了，有人可以向我解释什么错了吗？用它？

**script.js**
var myApp = angular.module('myModule', []).controller("myController", function ($scope) {
var emp = [
{firstName:"Ben",lastName:"Ding",DOB:new Date('December 26, 1991'),gender:"Male",salary:500},
{firstName:"John",lastName:"Deo",DOB:new Date('December 26, 1991'),gender:"Male",salary:6500.21},
{firstName:"Rajesh",lastName:"kumar",DOB:new Date('December 26, 1991'),gender:"Male",salary:3500},
{firstName:"Rashmi",lastName:"singh",DOB:new Date('December 26, 1991'),gender:"female",salary:8500.78},
{firstName:"soumya",lastName:"kumari",DOB:new Date('December 26, 1991'),gender:"female",salary:30}
]
$scope.emp = emp;
$scope.rowLimit = 5;
$scope.sortColumn = name;
});
未应用过滤器的DOB值为“ 1991-12-25T18：30：00.000Z”，其中包含30。这就是未应用过滤器的原因。您可以将薪水30更改为其他任何数字，然后尝试使用，这样就可以了。日期值将根据当前日期和时间而更改。
