導出jsp的特定表ID到excel

我有一個問題，我想知道如果有人可以幫助我。任何幫助真的很感激。我相信它是一個'容易'的問題。導出jsp的特定表ID到excel

我有一個jsp頁面顯示錶中的動態數據，我的問題是該頁面有多個表。但我想出口到Excel只有一個特定的ID與特定的表。

到目前爲止，我出口到擅長的所有數據從jsp頁面是錯誤的，因爲我想只導出一個表格id =「formAssignDemands」，我該怎麼做呢？

這裏是我的代碼，

我設法用JavaScript來做到這一點，並正在努力在3個基本瀏覽器Mozilla，Chrome和IE11，所以這裏是，

  <script type="text/javascript"> 
     function ExcelReport() 
     { 
     var tab_text="<table border='2px'><tr bgcolor='#FFFFFF'>"; 
     var textRange; var j=0; 
     tab = document.getElementById('table_id'); // id of table 

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

tab_text=tab_text+"</table>"; 
tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, ""); 
tab_text= tab_text.replace(/<img[^>]*>/gi,""); 
tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); 
var ua = window.navigator.userAgent; 
var msie = ua.indexOf("MSIE "); 

if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))  
{ 
    txtArea1.document.open("txt/html","replace"); 
    txtArea1.document.write(tab_text); 
    txtArea1.document.close(); 
    txtArea1.focus(); 
    sa=txtArea1.document.execCommand("SaveAs",true,"Excel.xls"); 
} 
else     
    sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text)); 

    return (sa); 
    } 

    </script>

，並somewere把它在你的身體可以添加以下有一個iframe，這樣，

<iframe id="txtArea1" style="display:none"></iframe>  
    <button id="btnExport" class="button_class" onclick="ExcelReport();">Export to Excel</button>

完蛋了，塔恩你們閱讀
