I perform live search in php using ajax. This is my code for performing task googleajax.php
<?php
$id=$_GET['id'];
if(isset($_POST['submit']))
{
$temp=$_POST['name'];echo $temp;
}
?>
<html>
<head>
<script language="javascript" type="text/javascript">
function getXMLHTTP() { //function to return the xml http object
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getValue(id)
{
var strURL="googledata.php?id="+id;
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('div1').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:
" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
</script>
</head>
<body>
<form method="post">
<?php
/*$query="Select * from tblcountry where country_id='".$id."'";
echo $
$res=mysql_query($res);
while($row=mysql_fetch_assoc($res))
{
extract($row);*/
?>
<input type="text" id="name" name="name" onKeyUp="getValue(this.value)" value="<?php echo $id;?>" />
<input type="submit" id="submit" name="submit" value="serch">
<div id="div1" name="div1">
</div>
<?php
/*<!--}-->*/
?>
</form>
</body>
</html>
and googledata.php
<?php
$con=mysql_connect("localhost","root","");
if(!$con)
{
die("error in connection");
}
else
{
mysql_select_db("hms2012",$con);
}
$id= $_GET['id'];
if($id=="")
{
}
else
{
$result=mysql_query("select * from tblcountry where country_name like '$id%'");
while($row=mysql_fetch_assoc($result))
{
extract($row);
echo "<option value='$country_id'><a href='googleajax.php?id=$country_id'>".$country_name."</a><br></option>";
}
}
?>
Performing this code I can not select value for press key. What was the use that I can select the value?
