I have a jsp which onload calls a js in which a table is created dynamically. The situation is that I have never worked on jquery earlier, all I know is javascript.
I made two scenarios:
case one : when I create static table on the jsp page itself it works flawlessly. case two : when I try to load the same table which is created by dynamic javascript it fails.
Case I Working code
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="../js/jquery.js"></script>
<script type="text/javascript" src="../js/createDynamicTable.js"></script>
<script type="text/javascript" src="../js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
$('#testTable').dataTable();
});
</script>
</head>
<body>
<div id="tableDataDiv">
<table id="testTable">
<thead>
<th>h1</th>
<th>h2</th>
<th>h3</th>
</thead>
<tbody>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>8</td>
<td>9</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
Case II Not Working code
jsp code
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="../js/jquery.js"></script>
<script type="text/javascript" src="../js/createDynamicTable.js"></script>
<script type="text/javascript" src="../js/jquery.dataTables.js"></script>
<script>
$(document).ready(function() {
$('#testTable').dataTable();
});
</script>
</head>
<body onload="getTableData();">
<div id="tableDataDiv">
</div>
</body>
</html>
js code
function getTableData(){
var tableDataDivObj = document.getElementById("tableDataDiv");
var tableObj = document.createElement("table");
tableObj.id = 'testTable';
// header
var theadObj = document.createElement("thead");
var thObj = document.createElement("th");
thObj.innerHTML = 'h1';
theadObj.appendChild(thObj);
thObj = document.createElement("th");
thObj.innerHTML = 'h2';
theadObj.appendChild(thObj);
thObj = document.createElement("th");
thObj.innerHTML = 'h3';
theadObj.appendChild(thObj);
tableObj.appendChild(theadObj);
// body
var tbodyObj;
var trObj;
var tdObj;
tbodyObj = document.createElement("tbody");
var count = 1;
for(i = 0; i < 3; i++){
trObj = document.createElement("tr");
for(j = 0; j < 3; j++){
tdObj = document.createElement("td");
tdObj.innerHTML = count;
trObj.appendChild(tdObj);
count++;
}
tbodyObj.appendChild(trObj);
}
tableObj.appendChild(tbodyObj);
tableDataDivObj.appendChild(tableObj);
}
Once the table is created dynamically, we append it to the div on the jsp page.
Kindly suggest any modification, suggestions so that I can get this code work. this is just an example I have created of my real application . which involves complete mvc, where table data is retrived from the service methods and dao files. I am able to get the data into the table(I made sure after getting an alert on jsp page). I am not able to use datatable on the id of the table.
Thanks in advance!

When your dataTables initialization is run, the table doesn't exist yes. You can fix by moving the $('#testTable').dataTable(); after the table has been initialized.
$(tableObj).dataTable();
at the end of the getTableData function (which should be defined in your $(document).ready callback.
