css - 如何在ionic中动态删除css类

Question

我在我的 ionic 元素中使用 ionic 切换，当我在浏览器中打开应用程序时， ionic 切换生成的 html 是:

<div class="noToggleBorder item item-toggle toggle-large ng-empty ng-valid" ng-model="checkarrivee.boo[var.id]" ng-click="checkarrivee.isMissionSelected(var.id,checkarrivee.ficheDeMission.id)" toggle-class="toggle-positive">
    <div ng-transclude=""><span class="ng-binding">Ceintures De Sécurités Passagères</span></div>
    <label class="toggle toggle-positive disable-user-behavior">
        <input type="checkbox" ng-model="checkarrivee.boo[var.id]" class="ng-pristine ng-untouched ng-valid ng-empty">
        <div class="track">
            <div class="handle"></div>
        </div>
    </label>
</div>

我的问题是:如何从这个 div 中动态删除元素类？？

Answer 1

<div class="noToggleBorder item-toggle toggle-large ng-empty ng-valid" ng-class="{item: checkValue()}" ng-model="checkarrivee.boo[var.id]" ng-click="checkarrivee.isMissionSelected(var.id,checkarrivee.ficheDeMission.id)" toggle-class="toggle-positive">
<div ng-transclude=""><span class="ng-binding">Ceintures De Sécurités Passagères</span></div>
<label class="toggle toggle-positive disable-user-behavior">
    <input type="checkbox" ng-model="checkarrivee.boo[var.id]" class="ng-pristine ng-untouched ng-valid ng-empty">
    <div class="track">
        <div class="handle"></div>
    </div>
</label>
</div>

将“item”类放入 ng-class 并根据表达式显示元素类。
