如何使用angularjs使用过滤器进行ng-repeat? [英] How to do ng-repeat with filter using angularjs?

问题描述

在这里，我添加了我想根据用户输入进行搜索的代码，但是

Here I added my code i want to search based on user input i tried this but

filter: first_name_model

我没有得到正确的结果

例如:运行代码片段

输入"2"并查看结果(我们只需要获取一条记录，但它会显示所有记录)

enter "2" and see the result (we need to get only one record but it showing all records )

输入"as"并查看结果(我们只需要获取一条记录(asif yohana)，但显示2条记录)

enter "as" and see the result (we need to get only one record(asif yohana) but it showing 2 records )

我只想过滤这两个字段

1.no

2.DisplayName

2.DisplayName

可能需要使用"OR"条件.

may be need to use 'OR' condition .

帮我前进

angular.module('myApp', []).controller('namesCtrl', function($scope) {

    $scope.students = [{
            "firstname": "irfan",
            "lastname": "k",
			"no":"2",
            "userid": "5706b916bb729ecc876192d2"
        },
        {
            "firstname": "asif",
            "lastname": "Y",
			"no":"3",
            "userid": "5706b916bb729ecc87619245"
        },
		
		{
            "firstname": "arun",
            "lastname": "D",
			"no":"6",
            "userid": "5706b916bb729ecd876452d2"
        },
		{
            "firstname": "smart",
            "lastname": "k",
			"no":"5",
            "userid": "5706b916bb729ecc876452d2"
        },
		{
            "firstname": "rajesh",
            "lastname": "v",
			"no":"4",
            "userid": "5706b916bb729ecc87619245"
        }
    ];

    $scope.users = [{
            "_id": "5706b916bb729ecc87619245",
            "DisplayName": "irfan kadhar",
           

        },
        {
            "_id": "5706b916bb729ecc876192d2",
            "DisplayName": "asif yohana",
            

        },
		{
            "_id": "5706b916bb729ecc876452d2",
            "DisplayName": "smar kiran",
            

        },
		{
            "_id": "5706b916bb729ecd876452d2",
            "DisplayName": "arun dinesh ",
            

        }
    ]

    if ($scope.students) {

        for (var i = 0; i < $scope.students.length; i++) {

            for (var j = 0; j < $scope.users.length; j++) {

                if ($scope.students[i].userid == $scope.users[j]._id) {

                    $scope.students[i].AssignedToDisplayName = $scope.users[j].DisplayName;

                }

            }

        }

    }

推荐答案

请将输入的ng-model更改为 first_name_model.no 它对我有用

Please change ng-model of input to first_name_model.no It works form me

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<div ng-app="myApp" ng-controller="namesCtrl">
         filter data <input type = "text" ng-model = "first_name_model.no"/><br><br><br>
         <table>
            <tr>
               <th>Number</th>
               <th>DisplayName</th>
            </tr>

            <tr ng-repeat="student in students | filter: first_name_model">
               <td><input type="text" ng-model ="student.no"></td>

               <td>
                  <select  ng-model="student.userid"  placeholder="Assigned To" name="userid{{$index}}" >
                  <option ng-repeat="user in users | orderBy: 'DisplayName'" ng-value="user._id">
                     {{user.DisplayName}}</md-option>
                     </md-select>
               </td>
            </tr>
         </table>
      </div>
