Question

如何在不提交表单的情况下触发错误消息，因为当我单击输入字段而未键入内容时，如果单击输入字段，则会触发验证错误，指出此字段不能为空。我尝试使用＆＃39; data-parsley-trigger =＆＃34; keyup＆＃34;＆＃39;但仅在输入字段中输入内容时才有效

例如，如果您单击此网站上的标题字段https://deals.jumia.cm/en/posts/new并且未在字段中键入任何内容，则单击标题字段，它将触发验证错误

<form method="post" class="ad-form"  enctype="multipart/form-data" data-parsley-validate >      
   <label for="title">Title</label>                 
   <input type="text" id="title" name="title" placeholder="Title" required="required" data-parsley-maxlength="255" data-parsley-maxlength-message="Title can&#039;t have more than 255 signs." data-parsley-required-message="Please enter a title." data-trigger="focus" data-toggle="popover" data-content="Keep the title short and clear. Do not write the price in it or any information that is not relevant." data-parsley-validate-if-empty data-parsley-trigger="keyup"/> 
<script>
   $(document).ready(function(){
   $('[data-toggle="popover"]').popover();   
    });
   $('.popover-dismiss').popover({
   trigger: 'focus'
   })
 </script>

   <label for="category">Category</label>                        
   <select id="Category" name="category" required="required" data-parsley-required-message="Please select a Category." data-level="0">
   <option value="">Select Category</option>
   </select>                                            
   <label for="subcategory">Subcategory</label>                           
   <select id="Subcategory" name="subcategory" data-parsley-required-message="Please select a subcategory.">
   <option value="">Select Category first</option>
   </select>                            
   </form>
