摘要:[使用HiddenField]記住多筆畫面資料給後端繫結
Javascript、JQuery
<script type="text/javascript" language="javascript">
$(function () {
//匯入中請等待(動畫)
$('#Process').hide();
$('.import').click(function () {
$('#Process').animate({ width: '100px', height: '50px' }, "slow");
$('#Process').show();
});
});
//記住多筆畫面資料給後端繫結
var mySubmit = function () {
var $trs = $('.ListView_Table tr');
var size = $trs.size();
if (size > 2) {
$trs = $trs.slice(1, size - 1);
var data = "";
$trs.each(function (n) {
var empno = $.trim($(this).find('td :hidden[name$=hidEmpno]')[0].value);
var ispocket = $.trim($(this).find('td :input[name$=ddlIsOK]')[0].value);
var remark = $.trim($(this).find('td :input[name$=txtRemark]')[0].value);
if (data.length != 0) {
data = data + "|";
}
data = data + empno + ":" + ispocket + ":" + remark;
});
//把值塞入ASP.NET HiddenField 控制項
$(':hidden[name$=hiddenData]').val(data);
