Adding parameter to ng-click function inside ng-re-第2页回答

I have a simple loop with ng-repeat like this:

<li ng-repeat='task in tasks'>
  <p> {{task.name}}
  <button ng-click="removeTask({{task.id}})">remove</button>
</li>

There is a function in the controller $scope.removeTask(taskID).

As far as I know Angular will first render the view and replace interpolated {{task.id}} with a number, and then, on click event, will evaluate ng-click string.

In this case ng-click gets totally what is expected, ie: ng-click="removeTask(5)". However... it's not doing anything.

Of course I can write a code to get task.id from the $tasks array or even the DOM, but this does not seem like the Angular way.

So, how can one add dynamic content to ng-click directive inside a ng-repeat loop?

Here is the ng repeat with ng click function and to append with slider

<script>
var app = angular.module('MyApp', [])
        app.controller('MyController', function ($scope) {
        $scope.employees = [
            { 'id': '001', 'name': 'Alpha', 'joinDate': '05/17/2015', 'age': 37 },
            { 'id': '002', 'name': 'Bravo', 'joinDate': '03/25/2016', 'age': 27 },
            { 'id': '003', 'name': 'Charlie', 'joinDate': '09/11/2015', 'age': 29 },
            { 'id': '004', 'name': 'Delta', 'joinDate': '09/11/2015', 'age': 19 },
            { 'id': '005', 'name': 'Echo', 'joinDate': '03/09/2014', 'age': 32 }
        ]

            //This will hide the DIV by default.
                $scope.IsVisible = false;
            $scope.ShowHide = function () {
                //If DIV is visible it will be hidden and vice versa.
                $scope.IsVisible = $scope.IsVisible ? false : true;
            }
        });
</script>
</head>

<body>

<div class="container" ng-app="MyApp" ng-controller="MyController">
<input type="checkbox" value="checkbox1" ng-click="ShowHide()" /> checkbox1
<div id="mixedSlider">
                    <div class="MS-content">
                        <div class="item"  ng-repeat="emps in employees"  ng-show = "IsVisible">
                          <div class="subitem">
        <p>{{emps.id}}</p>
        <p>{{emps.name}}</p>
        <p>{{emps.age}}</p>
        </div>
                        </div>


                    </div>
                    <div class="MS-controls">
                        <button class="MS-left"><i class="fa fa-angle-left" aria-hidden="true"></i></button>
                        <button class="MS-right"><i class="fa fa-angle-right" aria-hidden="true"></i></button>
                    </div>
                </div>
</div>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script> 
<script src="js/multislider.js"></script> 
<script>

        $('#mixedSlider').multislider({
            duration: 750,
            interval: false
        });
</script>
