is to use ng-dialog to generate a pop-up box. After that, the written message reminder box is buried behind the dialog box:

ng-dialog corresponding pop-up box code is:
`<span ng-app="fanApp">

<p class="panel panel-success" style="height: 99%;z-index: 2;" ng-controller="plan_add">

</p>

</span>`

The z-index of the message reminder box behind the pop-up box is 9999.
