Dropdown value selection

[ghjk]

I have a drop down box and the test box for the search field. In there I user only dropdown box to search values from the DB. But now I want to pass text box value with dropdownbox value. How can I do that? This is my working php code for only dropdown search.

<table width="508" align="center"  border="0">
				<form>
				 <tr>
					<td width="169">
					<select name="users" onchange="showUser(this.value);">
						<option value="1">Name</option>
						<option value="2">Number</option>
						<option value="3">Phone Number</option>
						<option value="4">Email Address</option>
					</select>
					</td>
					<td colspan="2" ><input name="search" type="text" size="40" value=""/></td>
				<td width="76"><input src="images/Search.jpg" type="image"  alt="Confirm"  name="search"  /></td>
				  </tr>
				  </form>
				</table><?php
				?>
		 <div id="txtHint"></div>

This is my ajax code

function showUser(str)
{
	
	req= GetXmlHttpObject();
	var url="User.php";
	url=url+"?q="+str;
	
	url=url+"&sid="+Math.random();
	
	req.onreadystatechange=stateChanged;
	req.open("GET",url,true);
	req.send(null);
}
function stateChanged()
 {
if (request.readyState==4)
	{
		document.getElementById("txtHint").innerHTML=request.responseText;
	}
 }
