实用导出：JavaScript （JS）操作web页面导出为Excle示例

 

在日常的开发中，经常会遇到一些报表导出，这里有一个简单的页面导出！

不过有一点，要对IE的ActiveX进行设置，具体的写在源码，文档里了！可以进行下载。

<table id="tableExcel" width="100%" border="1" cellspacing="0" cellpadding="0"> 
		     <tr> 
		         <td colspan="5" align="center">WEB页面导出为EXCEL示例</td> 
		   </tr> 
		   <tr> 
		        <td>列标题1</td> 
		        <td>列标题2</td> 
		       <td>列标题3</td> 
		        <td>列标题4</td> 
		        <td>列标题5</td> 
		    </tr> 
		    <tr> 
		       <td>aaa</td> 
		       <td>bbb</td> 
		       <td>ccc</td> 
		        <td>ddd</td> 
		        <td>eee</td> 
		    </tr> 
		    <tr> 
		       <td>AAA</td> 
		        <td>BBB</td> 
		       <td>CCC</td> 
		        <td>DDD</td> 
		        <td>EEE</td> 
		    </tr> 
		   <tr> 
		        <td>FFF</td> 
		        <td>GGG</td> 
		        <td>HHH</td> 
		        <td>III</td> 
		        <td>JJJ</td> 
		    </tr>  
		</table> 

 

按钮：

<input type="button" onclick="javascript:method1('tableExcel');" value="第一种方法导入到EXCEL"> 
<input type="button" onclick="javascript:method2('tableExcel');" value="第二种方法导入到EXCEL"> 
<input type="button" onclick="javascript:getXlsFromTbl('tableExcel',null);" value="第三种方法导入到EXCEL"> 

以下是三个按钮对应的JS函数：

  函数1：

function method1(tableid) {//整个表格拷贝到EXCEL中 
	    var curTbl = document.getElementById(tableid); 
	    var oXL = new ActiveXObject("Excel.Application"); 
	    //创建AX对象excel 
	    var oWB = oXL.Workbooks.Add(); 
	    //获取workbook对象 
	        var oSheet = oWB.ActiveSheet; 
	   //激活当前sheet 
	    var sel = document.body.createTextRange(); 
	   sel.moveToElementText(curTbl); 
	   //把表格中的内容移到TextRange中 
	    sel.select(); 
	    //全选TextRange中内容 
	    sel.execCommand("Copy"); 
	    //复制TextRange中内容  
	    oSheet.Paste(); 
	    //粘贴到活动的EXCEL中       
	    oXL.Visible = true; 
	    //设置excel可见属性 
	} 
	function method2(tableid) //读取表格中每个单元到EXCEL中 
	{
