吴-隐藏不隐藏按钮

Question

如果是delete文件夹，我想隐藏按钮，并显示是否是收件箱。下面的代码不工作，因为按钮总是显示。

<div class="message-footer-height"  >
   <div class="custom-div-class" ng-click=""  > 
      <button class="custom-btn-default" 
         ng-hide="messageState.details && itemTappedValue = 'delete'"
         ng-class="{ 'msg-btn' : userMessageDetails.id === -1 }" 
         ng-click="deleteMessage()" >
            {{"button.delete"|translate}}
      </button>
   </div>
</div>

谢谢

Answer 1

您需要使用==，==是松散等式，===是严格相等的。在这里阅读更多sameness

  <div class="message-footer-height"  >
    <div class="custom-div-class" ng-click=""> 
      <button class="custom-btn-default" 
        ng-hide="messageState.details && itemTappedValue == 'delete'"
        ng-class="{ 'msg-btn' : userMessageDetails.id === -1 }"
        ng-click="deleteMessage()">
          {{"button.delete"|translate}}
      </button>
    </div>
  </div>

这里需要双等号itemTappedValue = 'delete'
