导出报表的实现

前端页面

这是和jqgrid结合的表单导出,第一步就是从表格中取出要传到后台的参数
<script type="text/javascript" th:inline="javascript">
/*<![CDATA[*/
function loanTransferExport(){
// 取得要提交的参数
var ids = $('#jqgrid').getDataIDs();//返回数据表的ID数组["66","39"..]
var len = ids.length;
var projectIds = new Array();
for(var i=0; i<len; i++){
var getRow = $('#jqgrid').getRowData(ids[i]);//获取当前的数据行
projectIds.push(getRow.id);
}
var data = JSON.stringify(projectIds);
$('<input type="text" name="projectIds" />').attr("value",data).appendTo("form");
// 提交表单
$("#cdzyForm").submit();
$.successBox("出账划转数据Excel导出成功");
// 注意return false取消链接的默认动作
return false;
}
/*]]>*/
</script>
