如何将网页表格内容导入excel_javascript技巧

将访问的页面加入到可信任站点

复制代码代码如下:

//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<script type="text/javascript" src="execl.js"></script>
//添加按钮<input style="height:26px" type="button" name="btnExcel" value="导出excel" onClick="ExportExcel(this,'tableNr','','表头');"/>
//将table表的id和class设置为tableNr
