我還可以通過示波器放置示波器嗎？

Question

如果選擇了另一個按鈕，我做了一個任務過濾器，並且需要編輯titel的tekst，我嘗試了一個作用域，但是如果作用域不起作用，你們可能不知道mayby還有其他辦法嗎？

我在談論它的規則$ scope，infotitel，我也嘗試將作用域函數放在上面的過濾器中，但這也不起作用。

這是我的過濾器代碼

$ scope.infoTitel ='完成'; -------------我將其放在每個if語句中，因為在單擊時它會將任務過濾掉是否完成，但是我要使用的范圍顯示html中的tekst completted etcc

return function(values, taskCompleted) {

  // filter
  return values.filter(function(value){
    if(taskCompleted === 1) {
                $scope.infoTitel = 'completed';
        return value.completed;
    }
    else if(taskCompleted === 2){
                $scope.infoTitel = 'all';
        return true;
    }
            else if(taskCompleted === 3){
                $scope.infoTitel = 'deadline missed';
        return value.dateExpired;
    }
            // initially don't filter
            else if(!value.completed && !value.dateExpired){
                $scope.infoTitel = 'to do';
                return value;
            }

    //return $sce.trustAsHtml(output); voor als html verandert

  });
};

這是按鈕所在的部分

<div class="mini-nav">
            <a class="clear-completed" ng-click="taskfilter = 3" ng-class="{'active' : taskfilter == 3}">
                <span>deadline missed</span>.
            </a>
            <a class="clear-completed" ng-click="taskfilter = 2" ng-class="{'active' : taskfilter == 2}">
                <span>show all </span>.
            </a>
            <a class="clear-completed" ng-click="taskfilter = 1" ng-class="{'active' : taskfilter == 1}">
                <span>show completed</span>.
            </a>

            <a class="clear-completed" ng-click="taskfilter = 0" ng-class="{'active' : taskfilter == 0}" ng-init="">
                <span>to do</span>.
            </a>
        </div>

這是html，第一行是我要顯示它的位置

li ng-repeat =“任務中的todo | filterTask：taskfilter” ng-class =“ getCSSClass（todo）” ------------- filterTask是我想放入的自定義過濾器范圍tekst在其中，因此是第一段代碼。

{{infoTitel}}由家人

-----------這是我想要的東西

<h1>{{ infoTitel }} by family</h1>

    <div id="main" style="display: block;">
        <ul id="todo-list" class="unstyled">
            <li ng-repeat="todo in tasks | filterTask:taskfilter " ng-class="getCSSClass(todo)" >
                <div class="view" ng-keyup="editTodo()">
                    <input type="checkbox" ng-click="toggleTodo(todo)" class="check-done-{{todo.completed}}"  ng-hide= "todo.dateExpired "/>
                    <span class="done-{{todo.completed}}">{{todo.task}} </span>
                    <p ng-show="todo.completed">completed by: {{ todo.completedBy.name }} </p>
                    <p ng-show="todo.completed">date completed : {{ todo.dateCompleted | date : "MMM d, y h:mm a" }}</p>
                    <p ng-hide="todo.completed" ng-if= " !todo.dateExpired ">task deadline : {{ todo.timeToDeadline || "no deadline" | date : "MMM d, y h:mm"  }}</p>
                    <p ng-hide="todo.completed" ng-if= " todo.dateExpired ">deadline missed on {{ todo.dateExpiration | date : "MMM d, y h:mm a"}}</p>
                    <div class="bar-holder" ng-show="todo.percentage || todo.percentage == 0"  ng-if="!todo.completed " >
                      <div class="bar" style="width: {{todo.percentage}}%;" ></div>
                    </div>
                </div>
                <input class="edit" type="text" ng-model="todo.text" ng-keyup="editOnEnter(todo)" />
            </li>
        </ul>

我發現了問題，我可以直接在按鈕內更改tekst，添加另一次點擊，然后直接在其中添加tekst，這樣它就可以在

{{infoTitel}}由家人

<div class="mini-nav">
            <a class="clear-completed" ng-click="taskfilter = 'missed'; infoTitel = 'Deadline missed'" ng-class="{'active' : taskfilter == 'missed'}">
                <span>deadline missed</span>
            </a>
            <a class="clear-completed" ng-click="taskfilter = 'all'; infoTitel = 'All'" ng-class="{'active' : taskfilter == 'all'}">
                <span>show all </span>
            </a>
            <a class="clear-completed" ng-click="taskfilter = 'completed'; infoTitel = 'Completed'" ng-class="{'active' : taskfilter == 'completed'}">
                <span>show completed</span>
            </a>
            <a class="clear-completed" ng-click="taskfilter = 'todo'; infoTitel = 'To do'" ng-class="{'active' : taskfilter == 'todo'}" ng-init="">
                <span>to do</span>
            </a>
        </div>

ps：將3、2、1,0個過濾器名稱更改為missed，all，complete和todo，以更好地了解過濾器
