[英]How to get the dynamic table id value and to pass it to javascript function
我需要您的幫助來獲取表的ID值並將該值傳遞給javascript函數。 我在表格中有一個圖片,我想點擊它,要捕獲的表格ID並將其傳遞給javascript函數。 這是表代碼:
<table class="tablesorter" id="detailsTable<%=tableCounter%>" width="80%">
<tr>
<td>
<a href="javascript:fnExcelReport();">
<img border="0" src="../Images/excel_icon.png" alt="Export to Excel"></a>
</td>
</tr>
</table>
還有需要將ID傳遞給它的javascript函數(第7行):
<script type="text/javascript">
function fnExcelReport()
{
var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>";
var textRange; var j=0;
tab = document.getElementById('detailsTable1'); // 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,"Say Thanks to Sumit.xls");
}
else //other browser not tested on IE 11
sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));
return (sa);
}
</script>
這樣就解決了問題:
<table class="tablesorter" id="detailsTable<%=tableCounter%>" width="80%">
<tr>
<td>
<img onclick="fnExcelReport(this);" border="0" src="../Images/excel_icon.png" alt="Export to Excel">
</td>
</tr>
</table>
和javascript代碼:
function fnExcelReport(ele) {
var tableid = ele.parentNode.parentNode.parentNode.parentNode.id;
// etc.
}
您必須獲取圖像(觸發)的parentElement.id
。
您可以向圖像添加一個class
,以確保這是所需的圖像。
快速而骯臟的代碼段:
<img class="trigger" border="0" src="../Images/excel_icon.png" alt="Export to Excel"></a>
window.addEventListener("click", function(e){ //instead of window you can also add your element
if (e.target.className == "trigger"){
var table = e.target.parentElement.parentElement.parentElement.parentElement;
fnExcelReport(table.id;);
}
})
然后:
function fnExcelReport(id)
{
var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>";
var textRange; var j=0;
tab = document.getElementById(id); // id of table
