如何使用jquery按用户选择的顺序将选中的复选框放入文本框？每次我选择一个随机复选框时，文本框的值取决于复选框列表的模式。这是我的代码：

<label>Favorite activities and areas: (Please check the box in order of priorities)</label>
<input type="checkbox" class="chckbox" value="C"/>C
<input type="checkbox" class="chckbox" value="C#"/>C#
<input type="checkbox" class="chckbox" value="PHP"/>PHP
<input type="checkbox" class="chckbox" value="Javascript"/>Javascript
<input type="checkbox" class="chckbox" value="Java"/>Java
<hr>
<input type="text" id="subject_areas" placeholder="Selected Checkboxes" disabled>

这是我的jquery代码：

<script type="text/javascript">
  $(document).ready(function(){
   $('.chckbox').click(function(){
   var text = "";
   $('.chckbox:checked').each(function(){
    text += $(this).val() + ', ';
   });
   text = text.substring(0,text.length-2);
   $('#subject_areas').val(text);
   });
 });
</script>

例如，我选择PHP，然后选择C，然后文本框的值为“ C，PHP”，那是错误的。我要的值是“ PHP，C”。请帮我。谢谢。

一种方法是设置一个数组变量，您可以根据val toXmlEntityMarshaller: ToEntityMarshaller[department] = ??? val toJsonEntityMarshaller: ToEntityMarshaller[department] = ??? implicit val departmentMarshaller = Marshaller.oneOf(toJsonEntityMarshaller, toXmlEntityMarshaller) def route = parameters("department") { departmentName => // capture the Accept header in case the client did request one optionalHeaderValueByType[Accept] { maybeAcceptHeader => mapRequest ( _ .removeHeader(Accept.name) // set the Accept header based on the department .addHeader(maybeAcceptHeader.getOrElse( Accept(departmentName match { case "hr" ⇒ MediaTypes.`application/xml` case "tech" ⇒ MediaTypes.`application/json` }) )) ) ( // none of our logic code is concerned with the response type complete(department(departmentName)) ) } }属性来添加或删除该数组变量
