[SOLVED] check user exists in database

[vinpkl]

hi all

 

i m using the below script to check live check user in database.

 

This script works fine for me. I just need to have the same effect when the user enters the username and his cursor is still in the input box.

 

At present to show mesage whether the username exists or not the customer has to enter the username and then put the cursor in the next input field.

 

<script type="text/javascript"> 
function toggle_username(userid) { 
    if (window.XMLHttpRequest) { 
        http = new XMLHttpRequest(); 
    } else if (window.ActiveXObject) { 
        http = new ActiveXObject("Microsoft.XMLHTTP"); 
    } 
    handle = document.getElementById(userid); 
    var url = 'ajax.php?'; 
    if(handle.value.length > 0) { 
        var fullurl = url + 'do=check_username_exists&username=' + encodeURIComponent(handle.value); 
        http.open("GET", fullurl, true); 
        http.send(null); 
        http.onreadystatechange = statechange_username; 
    }else{ 
        document.getElementById('username_exists').innerHTML = ''; 
    } 
} 

function statechange_username() { 
    if (http.readyState == 4) { 
        var xmlObj = http.responseXML; 
        var html = xmlObj.getElementsByTagName('result').item(0).firstChild.data; 
        document.getElementById('username_exists').innerHTML = html; 
    } 
} 
</script> 
<input id="username" type="text" name="username" onchange="toggle_username('username')" /><br /> 
<div id="username_exists" style="font-size: 11px;font-weight: bold;color:#FF3300"> </div>
