我有一个待办事项列表，我希望当我单击“Strike marked”按钮时，所有选中的元素都被删除

这是我的代码index.html

 <!DOCTYPE html>
<html>
<head>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
    <style>
        .strike {
    text-decoration: line-through;
        }
    </style>
</head>

<body ng-app="myApp" ng-controller="todoCtrl">
<h2>My Todo List</h2>

<div ng-repeat="x in todoList">
    <input type="checkbox" ng-model="x.done"><span  ng-class="" ng-bind="x.todoText"></span>
</div>

<p>

    <button ng-click="strike()">Strike marked</button>

您不应该在任务的字符串
toText
上添加
class
属性。您应该改为在任务中添加一个
删除的
布尔属性：


$scope.strike = function() {
    angular.forEach($scope.todoList, function(x) {
        if (!x.done) x.striked = true;
    });
};


然后使用此布尔值添加css类：


<span ng-class="{strike: x.striked}" ng-bind="x.todoText"></span>



您需要使用ng类来实现相同的功能


ng-class="{isStriked : x.done}" 


代码


$scope.strike = function() {
    var oldList = $scope.todoList;
    angular.forEach(oldList, function(x) {
      x.isStriked = x.done;
    });
};



@tanja很高兴能帮助你..看看plukr，它会让你有更清晰的想法。。

$scope.strike = function() {
    var oldList = $scope.todoList;
    angular.forEach(oldList, function(x) {
      x.isStriked = x.done;
    });
};
