MVC3 Excel 导出
在MVC3的页面上，我开始是用js导出的Excel，
<script type="text/javascript">
function exportTableToExcel(table_id) {
alert("1");
var o_AXO = new ActiveXObject("Excel.Application");
alert("2");
var o_WB;
var o_Sheet;
try {
o_WB = o_AXO.Workbooks.Add();
//激活当前sheet
o_Sheet = o_WB.ActiveSheet;
} catch (err) {
alert("同时请确认已经安装好Excel软件");
return false;
}
var o_table = document.getElementById(table_id);
var row_len = o_table.rows.length;
for (i = 0; i < row_len; i++) {
var cell_len = o_table.rows[i].cells.length;
for (j = 0; j < cell_len; j++) {
var cellText = o_table.rows[i].cells[j].innerText;
o_Sheet.Cells(i + 1, j + 1).value = cellText;
}
}
o_AXO.Visible = true;
}
</script>但是换了台机子就不行了， var o_AXO = new ActiveXObject("Excel.Application");这句话不能执行了，以前是可以的，页面有一个table表，但是分页的就不行了，只能导出当前页面，请问JS能处理分页的导出吗，还有一种做法是后台导出，谁能给个成功的例子，要是MVC3的环境下，谢谢！！
