easyui表格导出excel
在table工具栏加导出按钮：
<table id="hwestable" class="easyui-datagrid"></table>
<div id="tb" style="padding:5px;height:auto">
<div style="text-align: right;">
<a href="#" class="easyui-linkbutton" id="exportExcel" iconCls="icon-export" plain="true">导出excel</a>
</div>
</div>
触发：
$(function(){
$("#exportExcel").click(function () {
Export("导出指标",$("#allindextable"));
});
});
Export方法：
function Export(strXlsName, exportGrid) {
var f = $('<form action="${ctx}/huawu/exportXls" method="post" id="fm1"></form>');
var i = $('<input type="hidden" id="txtContent" name="txtContent" />');
var l = $('<input type="hidden" id="txtName" name="txtName" />');
i.val(ChangeToTable(exportGrid));
i.appendTo(f);
l.val(strXlsName);
l.appendTo(f);
f.appendTo(document.body).submit();
document.body.removeChild(f);
}
