kindeditor 4 指定生成文件的時間日期/動態獲取My97的時間
阿新 • • 發佈：2018-11-15
info 獲取 turn eal dex iter val pattern calendar
最近後臺要求要指定上傳附件的時間日期,編輯器是kindeditor,仔細研究後發現可以借助clickToolbar事件,傳遞時間到後臺,但是中途發現傳遞的時間總是初始化my97的時間,改變後的時間只有在提交時才能生效
於是又研究了下My97,終於解決
1 <tr class="info">
2 <td class="text-right">自定義發布時間</td>
3 <td>
4 <fmt:formatDate value="<%=new Date()%>" pattern="yyyy-MM-dd HH:mm:ss" var
js
1 //需要動態設置my97的值到輸入框中否則無法獲取最新改變的時間
2 function setTime(dp) {
3 $("#time").attr("value",dp.cal.getNewDateStr(‘yyyy-MM-dd HH:mm:ss‘));
4 }
