如何将网页表格内容导入excel_javascript技巧

代码如下:

//导出到Excel，注意，表格标记内不得有注释，因为childNodes会把注释也算进去
//如果出错，需要关闭Excel，否则Excel进程会一直运行着
//td中只能有一个input值
//非td间不可以有组建 否则报缺少“；”错误
//引用页面加上
//添加按钮
//将table表的id和class设置为tableNr
function ExportExcel(btn,TabId,strCols,sTitle,sHeader,sFooter){
//alert('ssss');
btn.style.cursor = "wait";
event.returnValue = false;
//try{
var tab = document.getElementById(TabId);
// if(tab == null) tab = document.getElementById("dg")
//if(tab == null) tab = document.getElementById("db")
//if(tab == null) tab = document.getElementById(TabId)
if(tab == null){
alert("缺少表格对象");
btn.style.cursor = "hand";
return;
}
var t = tab.firstChild;
var rows = t.childNodes.length;
//alert(t.nodeName); //test
var tds = t.childNodes[0].childNodes.length;
var cols = 0;
for(var i=0;ivar td = t.childNodes[0].childNodes[i];
if(parseInt(td.colSpan)>1){
cols += parseInt(td.colSpan);
}
else{
cols++;
}
}
try{
var oXL = new ActiveXObject("Excel.Application");
}catch(e){
alert("请确认已经安装了Excel并允许运行Excel!");
alert("无法启动Excel，请确保电脑中已经安装了Excel!\n\n如果已经安装了Excel，"+"请将ip地址加入信任站点，并调整IE信任站点的安全级别。 \n具体操作： \n"+"工具 → Internet选项 → 安全 → 自定义级别 → ActiveX 控件和插件 → 对未标记为可安全执行脚本的ActiveX 控件初始化并执行脚本 → 启用 → 确定");
btn.style.cursor = "hand";
return;
}

var obook = oXL.ActiveWorkBook;
var osheets = obook.Worksheets;
var osheet = obook.Sheets(1);
