HTML导出Excel文件(兼容IE及所有浏览器)

2018-09-29 03:53:51来源：博客园阅读 ()

注意：IE浏览器需要以下设置：

打开IE，在常用工具栏中选择“工具”--->Internet选项---->选择"安全"标签页--->选择"自定义级别"--->弹出的窗口中找到ActiveX控件和插件--->
将"ActiveX控件自动提示"
"对没有标记安全的ActiveX控件进行初始化和脚本运行"
"下载未签名的ActiveX控件"
三项选择启用即可!

另外，我的功能需要替换掉td中隐藏的html元素，所以需要将新的table复制到另一个隐藏的div中。

页面html代码：

 1 <div id="divData">
 2     <table class="tablefrom" id="tbData" style="width: 100%; border-collapse: collapse;" border="0" cellspacing="0">
