Hi Friends,


Can you please send the link or example as how to add a row that contains drop down list dynamically, for me the list is coming from database.

Thanks,

What do you have so far? Were you able to put the data for the drop down in a request attribute?

If so, the next step is to try write a loop that goes through the data. Look at the c:forEach tag to do this. Once you've done that, you can add the code to output <option> for each value.

Which of these steps are you stuck on?

Here is the code


<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<html>

<head>

<title> Add/Remove dynamic rows in HTML table </title>

<script language="javascript">

function addRow(tableID) {

var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);

var cell1 = row.insertCell(0);
var element1 = document.createElement( '<select><option>' + item+ '</option></select>');
cell1.appendChild(element1);

}
</script>

</head>

<body>

<input type="button" value="Add Row" onclick="addRow('dataTable')" />

<input type="button" value="Delete Row" onclick="deleteRow('dataTable')" />

<table id="dataTable" border="1">

<tr>
<td valign="top">
<select NAME="choice" SIZE="5" width="20">
<c:forEach var="item" items="${list}">
<option>
<c:out value="${item}" />
</option>
</c:forEach>
</select>
</td>

</tr>
</table>

</body>

</html>

This is what I did so far.

This looks good. Does it do what you expect? You might want to add a value attribute to option.

Jayasri,
Can you hard code in 2 different html pages what you expect the javascript methods(addRow et deleteRow) to achieve? Please try that and post them. That way, it will be easier to work towards the solution.
 
It is sorta covered in the JavaRanch Style Guide.
