js实现把网页table导成Excel，bootstrap、JqGrid、Json
方案一：支持IE
//导出excel
function exportExcel(DivID,strTitle){
if(DivID==null)
{
return false;
}
var jXls, myWorkbook, myWorksheet;
try {
jXls = new ActiveXObject(\'Excel.Application\');
}
catch (e) {
alert("无法启动Excel!\n\n如果您确信您的电脑中已经安装了Excel，"+"那么请调整IE的安全级别。\n\n具体操作：\n\n"+"工具 → Internet选项 → 安全 → 自定义级别 → 对
没有标记为安全的ActiveX进行初始化和脚本运行 → 启用");
return false;
}
jXls.DisplayAlerts = false;
myWorkbook = jXls.Workbooks.Add();
var curTb = document.getElementById(DivID);
myWorksheet = myWorkbook.ActiveSheet;
myWorksheet.name=strTitle;
var sel = document.body.createTextRange();
sel.moveToElementText(curTb);
sel.select();
window.clipboardData.setData(\'text\',\'\');
sel.execCommand("Copy");
myWorksheet.Paste();
jXls.Visible = true;
try{
var fname = jXls.Application.GetSaveAsFilename("OA数据"+strTitle+".xls", "Excel Spreadsheets (*.xls), *.xls");
}catch(e){
print("Nested catch caught " + e);
}
finally{
if(fname!=false)
{
myWorkbook .SaveAs(fname);
alert("数据成功保存在:"+fname);
}
}
// myWorkbook .Close(savechanges=false);
// jXls.Quit();
window.clipboardData.setData(\'text\',\'\');
jXls = null;
myWorkbook = null;
myWorksheet = null;
