Jquery Mobile - 在关闭事件之前弹出

Question

我试图在触发关闭事件时运行一些检查（此代码正在运行），并且如果发现任何错误（并显示消息），则阻止弹出窗口关闭。

似乎JQM在关闭事件（或类似事件）之前没有。有可能这样做吗？

这是弹出窗口的HTML代码：

<div id="divPropertyPopup"
     class="ui-content form-horizontal"
     data-role="popup"
     data-overlay-theme="a"
     data-dismissible="false"
     style="min-width:30em; padding: 1em;">
    <a href="#" data-rel="back" data-role="button" data-theme="a" data-icon="delete" data-iconpos="notext"
       class="ui-btn-right">Close</a>
    <h4>Edit Optional Field Properties</h4>

    <div id="view_edit" data-role="fieldcontain" class="hidden">
        <div data-role="fieldcontain">
          <label style="padding: 0 !important; text-align: left !important;" class="preview_label"
                 for="functionmode">Form Function Mode</label>

          <select class="form-control" id="functionmode" title="Form Function Mode">
            <option value="edit">Edit Mode</option>
