          <input type="text"  onblur="namechange(this.value,'Articles_Title',{Articles_ID},'Articles_ID','articles')" value="{Articles_Title}">

          </span>

 

 

js file

 

// JavaScript Document



var xmlhttp;
//function namechange(name_fieldvalue)


function namechange(name_fieldvalue,name_fieldname,id_val,id_fieldname,table_name)
{
/*
alert(name_fieldvalue);
alert(name_fieldname);
alert(id_val);
alert(id_fieldname);
alert(table_name);
*/

if (name_fieldvalue.length==0)
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  }
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Your browser does not support XMLHTTP!");
  return;
  }
var url="ajax_namechange.php";
url=url+"?name_fieldvalue="+name_fieldvalue;
url=url+"&name_fieldname="+name_fieldname;
url=url+"&id_val="+id_val;
url=url+"&id_fieldname="+id_fieldname;
url=url+"&table_name="+table_name;
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}



function stateChanged()
{
if (xmlhttp.readyState==4)
  {
  document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
  }
}



function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}

 

 

 

php file for update

 

<?php
include("global.php");



$name_fieldvalue=$_GET["name_fieldvalue"];
$name_fieldname=$_GET["name_fieldname"];

$id_val = $_GET["id_val"];
$id_fieldname = $_GET["id_fieldname"];
$table_name = $_GET["table_name"];




$sq = "UPDATE $table_name SET $name_fieldname='".$name_fieldvalue."' WHERE $id_fieldname = '".$id_val."'";
echo $sq;


$DB_site->query($sq);


$response = "done1";

//output the response
echo $response;
?>
