Question

好的我有2条错误消息正在返回，而这些消息反过来显示同一条消息的2条消息。我怎么才能只显示一条消息？

jQuery.noConflict();

   jQuery(document).ready(function(){
      if (jQuery("span.errorMessage").length > 0) {                                                              
         var $this = jQuery("span.errorMessage");
         var t = $this.text();

         // Clear the text
         $this.text('');

         // Add new message
         $this.text('No search criteria was specified.');

         // Change the layout
         jQuery('#errorMessage').appendTo(jQuery('#message_display'));
      }
   });

为错误添加HTML

<span id="errorMessage">    
         <ul>
        <li><span class="errorMessage">No search criteria was specified.</span></li>
        <li><span class="errorMessage">No search criteria was specified.</span></li>
    </ul>
</span>

您似乎将文本附加到#errormessage，但清除＃this.text（）。我猜你需要在添加新错误之前清除#errormessage。

试试这个......

<div id="errorMessage">    
    <ul>
        <li><span class="errorMessage">1 No search criteria was specified.</span></li>
        <li><span class="errorMessage">2 No search criteria was specified.</span></li>
        <li><span class="errorMessage">3 No search criteria was specified.</span></li>
        <li><span class="errorMessage">4 No search criteria was specified.</span></li>
    </ul>
</div>

$(document).ready(function() {
    SetupMessageManager();
    $('.errorMessage').parent().hide();
    $('.errorMessage:first').parent().show();
});

返回jQuery 2错误消息，但只需要显示1
