Hi Friends,I am Dileep, from B'lore. I tried to use the code from..http://www.w3schools.com/php/php_ajax_livesearch.aspThis code is working fine when i checked it offline, i created 3 files namely ajaxlivesearch.htm, livesearch.php, links.xml. I published the same code online no results are shown.I appreciate any positive response to solve this problem.Thanks.--------<html><head><script type="text/javascript">function showResult(str){if (str.length==0) { document.getElementById("livesearch").innerHTML=""; document.getElementById("livesearch").style.border="0px"; return; }if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("livesearch").innerHTML=xmlhttp.responseText; document.getElementById("livesearch").style.border="1px solid #A5ACB2"; } }xmlhttp.open("GET","livesearch.php?q="+str,true);xmlhttp.send();}</script></head><body><form><input type="text" size="30" onkeyup="showResult(this.value)" /><div id="livesearch"></div></form></body></html>------------------<?php$xmlDoc=new DOMDocument();$xmlDoc->load("links.xml");$x=$xmlDoc->getElementsByTagName('link');//get the q parameter from URL$q=$_GET["q"];//lookup all links from the xml file if length of q>0if (strlen($q)>0){$hint="";for($i=0; $i<($x->length); $i++) { $y=$x->item($i)->getElementsByTagName('title'); $z=$x->item($i)->getElementsByTagName('url'); if ($y->item(0)->nodeType==1) { //find a link matching the search text if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q)) { if ($hint=="") { $hint="<a href='" . $z->item(0)->childNodes->item(0)->nodeValue . "' target='_blank'>" . $y->item(0)->childNodes->item(0)->nodeValue . "</a>"; } else { $hint=$hint . "<br /><a href='" . $z->item(0)->childNodes->item(0)->nodeValue . "' target='_blank'>" . $y->item(0)->childNodes->item(0)->nodeValue . "</a>"; } } } }}// Set output to "no suggestion" if no hint were found// or to the correct valuesif ($hint=="") { $response="no suggestion"; }else { $response=$hint; }//output the responseecho $response;?>

Respected Sir,I am happy to hear from you, Yes my server running PHP, i could run other php files there.NO Javascript errors, Kindly check this linkhttp://www.ambtion.com/0/search.phpthis should get original results as in w3schools.comhttp://www.w3schools.com/php/php_ajax_livesearch.aspThanking you, Dileep Kumar. D

Is your server running PHP? Are you getting any Javascript errors?

Add this code to the top of your PHP file:

ini_set('log_errors', 1);ini_set('error_log', dirname(__FILE__) . DIRECTORY_SEPARATOR . 'error.log');ini_set('html_errors', 0);ini_set('display_errors', 0);error_reporting(E_ALL);

That will send all PHP errors to a file called error.log in the same directory as the PHP script. There might be PHP errors that you just aren't seeing, using that code will send the errors to a log file that you can check later.

I'm not going to use that email address, but thanks anyway. I'm not here to fix your problems, I'm here to help you fix your problems.Create a file with this in it:

<?phpini_set('display_errors', 1);error_reporting(E_ALL);include 'file.php';?>

Replace the file.php filename there with the name of your actual PHP file. This is a file that turns on error messages and then includes your other file. Once you replace the filename and save that file on your server, open it in a browser. Don't use ajax, just type the URL of that PHP file into your browser and see what you get.

Sir,I changed it as you informed to to null but no results. It only works offline not online. xmlhttp.send(null);

your link is showing errorsError: uncaught exception: [Exception... "Not enough arguments" nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame :: http://www.ambtion.com/0/search.php :: showResult :: line 29" data: no]which is xmlhttp.send();try adding null to xmlhttp.send();xmlhttp.send(null);
