How to check Isavailablity in ajax?
- by udaya
Hi
This is what i have in my view page
<td width=""><input type="text" name="txtUserName" id="txtUserName" /></td>
<td><input type="button" name="CheckUsername" id="CheckUsername" value="Check Availablity"
onclick="Check_User_Name();"/></td>
Onclick of the button the Check_User_Name function in my ajax.js loads
This is the Check_User_Name function
function Check_User_Name(source)
{
var UserName = document.getElementById('txtUserName').value;
if(window.ActiveXObject)
User_Name = new ActiveXObject("Microsoft.XMLHTTP");
else if(window.XMLHttpRequest)
User_Name = new XMLHttpRequest();
var URL = newURL+"ssit/system/application/views/ssitAjax.php";
URL = URL +"?CheckUsername="+UserName;
User_Name.onreadystatechange = User_Name_Fun;
User_Name.open("GET",URL,true);
User_Name.send(null);
}
function User_Name_Fun()
{
document.getElementById('User_div').innerHTML=User_Name.responseText;
}
Then I can have the value in echo username then the $result has all the user name
Hows can i checkIsavailablity of username from here
if(($_GET['CheckUsername']!="") || (isset($_GET['CheckUsername'])))
{
echo $UserName = $_GET['CheckUsername'];//echo username
$_SESSION['state'] = $State;
$queryres = "SELECT dUser_name FROM tbl_login
WHERE dIsDelete='0'";
$result = mysql_query($queryres,$cn) or die("Selection Query Failed !!!");
