如何使用javascript仅在表格内部导出div

Question

我想将表格行内的特定div导出为ex​​cel。这个怎么做。如何获取表格ID中的可加入类div。

例：

<div class="addtable"> 
<table id="rer3233223"><tr><td>asasdasasd</td></tr></table> 
<table id="rer32343433"><tr><td>asasdasasd</td></tr></table> 
<table id="pijjj3232"><tr><td>asasdasasd</td></tr></table> 
<table id="ldffddf32"><tr><td>asasdasasd</td></tr></table> 
</div> 

下面的代码我使用基于标识导出表。

function fnExcelReport() 
    { 


     var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>"; 
     var textRange; var j=0; 
     tab = document.getElementById('addtable'); // id of table 

     for(j = 0 ; j < tab.rows.length ; j++) 
     {  
      tab_text=tab_text+tab.rows[j].innerHTML+"</tr>"; 
      //tab_text=tab_text+"</tr>"; 
     } 

     tab_text=tab_text+"</table>"; 
     tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, "");//remove if u want links in your table 
     tab_text= tab_text.replace(/<img[^>]*>/gi,""); // remove if u want images in your table 
     tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params 



     var ua = window.navigator.userAgent; 
     var msie = ua.indexOf("MSIE "); 

     if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))  // If Internet Explorer 
     { 
      txtArea1.document.open("txt/html","replace"); 
      txtArea1.document.write(tab_text); 
      txtArea1.document.close(); 
      txtArea1.focus(); 
      sa=txtArea1.document.execCommand("SaveAs",true,"MileReport"); 
     } 
     else     //other browser not tested on IE 11 
      sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text)); 

     return (sa); 
    }

<script> 
    function fnExcelReport() 
    { 
     var elms = document.getElementById('addtable').getElementsByTagName('table'); 

     var tab_text = new Array(); 

     for (var i = 0; i < elms.length; i++) {  

     tab_text[i]="<table border='2px'><tr bgcolor='#87AFC6'>"; 
     var textRange; var j=0; 
     var jsids=elms[i].id; 

     tab = document.getElementById(jsids); // id of table 

     for(j = 0 ; j < tab.rows.length ; j++) 
     {  
      tab_text[i]=tab_text[i]+tab.rows[j].innerHTML+"</tr>"; 
      //tab_text=tab_text+"</tr>"; 
     } 

     tab_text[i]=tab_text[i]+"</table>"; 

     tab_text[i]= tab_text[i].replace(/<A[^>]*>|<\/A>/g, "");//remove if u want links in your table 
     tab_text[i]= tab_text[i].replace(/<img[^>]*>/gi,""); // remove if u want images in your table 
     tab_text[i]= tab_text[i].replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params 

     } 

     var ua = window.navigator.userAgent; 
     var msie = ua.indexOf("MSIE "); 

     if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))  // If Internet Explorer 
     { 
      txtArea1.document.open("txt/html","replace"); 
      txtArea1.document.write(tab_text); 
      txtArea1.document.close(); 
      txtArea1.focus(); 
      sa=txtArea1.document.execCommand("SaveAs",true,"MileReport"); 
     } 
     else     //other browser not tested on IE 11 
      sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text)); 

     return (sa); 
    }
