使用AngularJS过滤表

Question

I just got into AngularJS and I'm trying to filter a table. So far I create my table dynamically, which works fine.

HTML:

<div ng-app="tableApp" ng-controller="tableAppController">
       <input type="text" class="form-control" ng-model="searchKey" placeholder="search..."/>

                        <div class="table-responsive">
                            <table class="table table-striped" id="trackingTable">
                                <thead>
                                    <tr>
                                        <th>No.r.</th>
                                        <th>a</th>
                                        <th>b</th>
                                        <th>c</th>
                                    </tr>
                                </thead>
                                <tbody>
                                    <tr ng-repeat="x in deviceData">
                                        <td>{{ $index + 1 }}</td>
                                        <td>{{x.a}}</td>
                                        <td>{{x.b}}</td>
                                        <td>{{x.c}}</td>
                                    </tr>
                                </tbody>
                            </table>
                        </div>
                    </div>
                    <script src="scripts/AngularJS/tableAppController.js"></script>

tableAppController.js:

var app = angular.module('tableApp', []);
app.controller('tableAppController', function ($scope) {
$scope.deviceData = [{a: "123", b: "123", c: "01.01.2001"}, {a: "dummyDeviceID2", b: "dummyCarID98", c: "01.01.2001"}];
});

I'm now trying to implement an filter, which filters data from the table based on an user input from a textfield. But only when a user types something inside the textbox ofcourse. I started to change the line <tr ng-repeat="x in deviceData"> in the html file to <tr ng-repeat="x in deviceData | filter:{'a':searchKey}"> Why is this approach not working and how can I solve this problem?

Answer 1

You should be able to use keys on your search object to do this:

<input type="text" class="form-control" ng-model="searchKey.a" placeholder="search..."/>

<tr ng-repeat="x in deviceData | filter:searchKey">

See line 36 in the official example for more context: http://plnkr.co/edit/YUfG7yzxBQ0gT9bsnTN2?p=preview

Answer 2

Try this :

{{ filter_expression | filter : expression : comparator}}

<tr ng-repeat="x in deviceData | filter : searchKey">
