    copied!<p>I want to output the selected values from the right hand listbox. However I am not successful in getting the values of selected values. The error returns from the submit function of js. Can anyone tell me why does it return: </p> <pre><code>An object doesn't support this property </code></pre> <p>in the submit function? How can i get the values.. will i use ajax or just returned value in PHP?</p> <pre><code> &lt;form name="frmListSubmit" method="post" id="myform" onsubmit="return submit()"&gt; &lt;table cellpadding="2" cellspacing="0" border="0" id="tblMain" class="edit"&gt; &lt;tr valign="top"&gt; &lt;td&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/td&gt; &lt;td&gt; &lt;SELECT id="s" size="10" name="source" multiple&gt; &lt;?php while($row = mysql_fetch_assoc($getEmployeeList)) { ?&gt; &lt;option name="list" value="&lt;?php echo $row['id'];?&gt;"&gt;&lt;?php echo $row['name']; ?&gt;&lt;/option&gt; &lt;?php } ?&gt; &lt;/td&gt; &lt;/SELECT&gt; &lt;td valign="center"&gt; &lt;a href="#" onclick="listbox_moveacross('s', 'd')" style="color:#FFF"&gt;&amp;gt;&amp;gt;&lt;/a&gt; &lt;a href="#" onclick="listbox_moveacross('d', 's')" style="color:#FFF"&gt;&amp;lt;&amp;lt;&lt;/a&gt; &lt;/td&gt; &lt;td&gt; &lt;SELECT id="d" size="10" name="destination" multiple&gt; &lt;option name="list" value=""&gt;&amp;nbsp;&lt;/option&gt; &lt;/SELECT&gt; &lt;input type="submit" name="submit" value="submit" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p>and here is the javascript code:</p> <pre><code>function listbox_moveacross(sourceID,destID) { var src=document.getElementById(sourceID); var dest=document.getElementById(destID); for(var count=0;count&lt;src.options.length;count++) { if(src.options[count].selected==true) { var option=src.options[count]; var newOption=document.createElement("option"); newOption.value=option.value; newOption.text=option.text; newOption.selected=true; try { dest.add(newOption,null);src.remove(count,null); } catch(error) { dest.add(newOption);src.remove(count); } count--; } } } function listbox_selectall(listID,isSelect) { var listbox=document.getElementById(listID); for(var count=0;count&lt;listbox.options.length;count++) { istbox.options[count].selected=isSelect; } } function submit() { listbox_selectall('d', true); return true; } </code></pre> <p>I have something like this in PHP and it returns only one ID after submission.</p> <pre><code>if(isset($_POST['submit'])) { echo $_POST['destination']; } </code></pre>
