kindeditor 4 指定生成文件的时间日期/动态获取My97的时间

最近后台要求要指定上传附件的时间日期,编辑器是kindeditor,仔细研究后发现可以借助clickToolbar事件,传递时间到后台,但是中途发现传递的时间总是初始化my97的时间,改变后的时间只有在提交时才能生效于是又研究了下My97,终于解决

     <tr class="info">
         <td class="text-right">自定义发布时间</td>
         <td>
             <fmt:formatDate value="<%=new Date()%>" pattern="yyyy-MM-dd HH:mm:ss" var="fmttime"></fmt:formatDate>
             <div class="">
                 <label for="time" class="col-md-2 control-label">
                 <input type="text" class="form-control" name="releaseTime" value="${fmttime}"  id="time" onClick="WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss',onpicked:function(dp){ setTime(dp) }})" disabled>
                 </label>
             </div>
         </td>
     </tr>

js

 //需要动态设置my97的值到输入框中否则无法获取最新改变的时间
 function setTime(dp) {
     $("#time").attr("value",dp.cal.getNewDateStr('yyyy-MM-dd HH:mm:ss'));
 }

 KindEditor.ready(function(k) {
     window.editor = k.create("textarea[name='content']",options);
     window.editor.clickToolbar("insertfile",function() {
         var releaseTime =$("#time").attr("value");
           $.ajax({
             url:"${pageContext.request.contextPath}/kindeditor/jsp/upload_json.jsp?releaseTime=" + releaseTime,
             dataType:"text",
                type:"GET",
                success:function() {

                }

         });
