in html, How can i change select-option menu with input html code?

My code works good in form select-option html code. But form input menu doesn't. Below is my code.

<script>
   function showUser(str)
 {
 if (str=="")
 {
 document.getElementById("txtHint").innerHTML="";
 return;
 } 
 if (window.XMLHttpRequest)
 {// code for IE7+, Firefox, Chrome, Opera, Safari
 xmlhttp=new XMLHttpRequest();
 }
 else
 {// code for IE6, IE5
 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 }
 xmlhttp.onreadystatechange=function()
 {
 if (xmlhttp.readyState==4 && xmlhttp.status==200)
 {
 document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
  }
}
 xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>
<form>
<select name="users" onchange="showUser(this.value)">
<option value="">Select a person:</option>
<option value="1">Peter Griffin</option>
<option value="2">Lois Griffin</option>
<option value="3">Glenn Quagmire</option>
<option value="4">Joseph Swanson</option>
</select>
</form>
<br>
<div id="txtHint"><b>Person info will be listed here.</b></div>

Above is good! but below is my code. why doesn't this work?? Input type="submit" doesn't work well, either. How can i overcome this problem??

 <script>
  same as above...
 </script>
 </head>
 <body>
 <form>
 <select name="users" onchange="showUser(this.value)">
  ## Here is wrong, input element.##
      <input type="text" name="users" onkeyup="showUser(this.value)>
 </select>
 </form>
 <br>
 <div id="txtHint"><b>Person info will be listed here.</b></div>

What is something wrong?? Help me!

You are missing an end quote

You have 

onkeyup="showUser(this.value)>

Should be: 

onkeyup="showUser(this.value)">

You also can't nest an <input> inside a <select>. See this jsfiddle and note the </select> is in red because it is invalid. The second select in the fiddle is done correctly.
