Ok explain me in simple formate. you want one text input with submit button and when some one will enter some text he will redirect some link . e.g http://test.com/TEXT_FROM_BOX?

Here is the code!!


<script type="text/javascript">

function red(){
var base_url = "http://www.test.com/"; // add your url with trailing slash.
var txt = document.getElementById("user_text").value;
if(txt == "") { alert('Enter some text'); } else { window.location = base_url + txt; }
}

</script>
<input type="text" size="30" name="user_text" id="user_text" />
<input type="button" onclick="red()" value="Submit / Redirect" />
