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
1 <tr class="info">
2 <td class="text-right">自定义发布时间</td>
3 <td>
4 <fmt:formatDate value="<%=new Date()%>" pattern="yyyy-MM-dd HH:mm:ss" var="fmttime"></fmt:formatDate>
5 <div class="">
6 <label for="time" class="col-md-2 control-label">
7 <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>
8 </label>
9 </div>
10 </td>
11 </tr>
js
1 //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
2 function setTime(dp) {
3 $("#time").attr("value",dp.cal.getNewDateStr(‘yyyy-MM-dd HH:mm:ss‘));
4 }

6 KindEditor.ready(function(k) {
7 window.editor = k.create("textarea[name=‘content‘]",options);
8 window.editor.clickToolbar("insertfile",function() {
9 var releaseTime =$("#time").attr("value");
10 $.ajax({
11 url:"${pageContext.request.contextPath}/kindeditor/jsp/upload_json.jsp?releaseTime=" + releaseTime,
12 dataType:"text",
