Hola ScriptShow.
Efectivamente el script utiliza AJAX.
Este es el codigo del archivo .js :
function getXmlHttpRequestObject() {
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
} else if(window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert("Tu navegador no es compatible. Intenta usando Mozilla Firefox, Apple Safari o Google Chrome");
}
}
//Our XmlHttpRequest object to get the auto suggest
var searchReq = getXmlHttpRequestObject();
//Called from keyup on the search textbox.
//Starts the AJAX request.
function searchSuggest() {
if (searchReq.readyState == 4 || searchReq.readyState == 0) {
var str = escape(document.getElementById('txtSearch').value);
searchReq.open("GET", 'searchSuggest.php?search=' + str, true);
searchReq.onreadystatechange = handleSearchSuggest;
searchReq.send(null);
}
}
//Called when the AJAX response is returned.
function handleSearchSuggest() {
if (searchReq.readyState == 4) {
var ss = document.getElementById('search_suggest')
ss.innerHTML = '';
var str = searchReq.responseText.split("\n");
for(i=0; i < str.length - 1; i++) {
//Build our element string. This is cleaner using the DOM, but
//IE doesn't support dynamically added attributes.
var suggest = '<div onmouseover="javascript:suggestOver(this);" ';
suggest += 'onmouseout="javascript:suggestOut(this);" ';
suggest += 'onclick="javascript:setSearch(this.innerHTML);" ';
suggest += 'class="suggest_link">' + str[i] + '</div>';
ss.innerHTML += suggest;
}
}
}
//Mouse over function
function suggestOver(div_value) {
div_value.className = 'suggest_link_over';
}
//Mouse out function
function suggestOut(div_value) {
div_value.className = 'suggest_link';
}
//Click function
function setSearch(value) {
document.getElementById('txtSearch').value = value;
document.getElementById('search_suggest').innerHTML = '';
}
Y este es el codigo del archivo .php:
<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT" );
header("Last-Modified: " . gmdate( "D, d M Y H:i:s" ) . "GMT" );
header("Cache-Control: no-cache, must-revalidate" );
header("Pragma: no-cache" );
header("Content-Type: text/xml; charset=utf-8");
//Get our database abstraction file
require('database.php');
///Make sure that a value was sent.
if (isset($_GET['search']) && $_GET['search'] != '') {
//Add slashes to any quotes to avoid SQL problems.
$search = addslashes($_GET['search']);
//Get every page title for the site.
$suggest_query = db_query(" SELECT rubro as suggest FROM comercios2 WHERE rubro LIKE('".$search."%') GROUP BY rubro UNION SELECT nombre as suggest FROM comercios2 WHERE nombre LIKE('".$search."%') GROUP BY nombre LIMIT 20 ");
while($suggest = db_fetch_array($suggest_query)) {
//Return each page title seperated by a newline.
echo $suggest['suggest']. "\n";
}
}
?>
El buscador emplea otro archivo (database.php) pero es donde esta seteada la conexión a la base de datos.
¿La función deberia ir en el archivo .js o en el html?
Saludos
