我是Ajax的新手,我試過教程書,但沒有奏效。代碼用於搜索。Ajax搜索不工作,而XML已經運行?
這是腳本search.htm
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>AJAX + MySQL I</title>
<script type="text/javascript" src="search.js"></script>
</head>
<body onload='process()'>
<h1>Student Search</h1>
<form name="form1">
Masukkan Nama Mahasiswa: <input type="text" id="namaMhs" />
</form>
<p><strong>Hasil Pencarian :</strong></p>
<div id="hasil" />
</body>
</html>
和JS腳本search.js
var xmlHttp = createXmlHttpRequestObject();
function createXmlHttpRequestObject()
{
var xmlHttp;
if(window.ActiveXObject)
{
try
{
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
xmlHttp = false;
}
}
else
{
try
{
xmlHttp = new XMLHttpRequest();
}
catch (e)
{
xmlHttp = false;
}
}
if (!xmlHttp) alert("Obyek XMLHttpRequest tidak dapat dibuat");
else
return xmlHttp;
}
function process()
{
if (xmlHttp.readyState == 4 || xmlHttp.readyState == 0)
{
nama =
encodeURIComponent(document.getElementById("namaMhs").value);
xmlHttp.open("GET", "search.php?namaMhs=" + nama, true);
xmlHttp.onreadystatechange = handleServerResponse;
xmlHttp.send(null);
}
else
setTimeout('process()', 1000);
}
function handleServerResponse()
{
if (xmlHttp.readyState == 4)
{
if (xmlHttp.status == 200)
{
var xmlResponse = xmlHttp.responseXML;
xmlRoot = xmlResponse.documentElement;
nimArray = xmlRoot.getElementsByTagName("nim");
namaMhsArray = xmlRoot.getElementsByTagName("namamhs");
alamatArray = xmlRoot.getElementsByTagName("alamat");
if (nimArray.length == 0)
{
html = "Data tidak ditemukan";
}
else
{
// membentuk tabel untuk menampilkan hasil pencarian
html = "<table border='1'><tr><th>NIM</th><th>Nama
Mhs</th><th>Alamat</th></tr>";
for (var i=0; i<nimArray.length; i++)
{
html += "<tr><td>" + nimArray.item(i).firstChild.data +
"</td><td>" +
namaMhsArray.item(i).firstChild.data +
"</td><td>" +
alamatArray.item(i).firstChild.data +
"</td></tr>";
}
html = html + "</table>";
}
document.getElementById("hasil").innerHTML = html;
setTimeout('process()', 1000);
}
else
{
alert("Ada masalah dalam mengakses server: " +
xmlHttp.statusText);
}
}
}
,並在PHP search.php中的最後一個腳本
<?php
header('Content-Type: text/xml');
echo '<hasil>';
$namaMhs = $_GET['namaMhs'];
mysql_connect("localhost","root","*******");
mysql_select_db("mahasiswa");
$query = "SELECT * FROM mhs WHERE namamhs LIKE '%$namaMhs%'";
$hasil = mysql_query($query);
while ($data = mysql_fetch_array($hasil))
{
echo "<mhs>";
echo "<nim>".$data['NIM']."</nim>";
echo "<namamhs>".$data['NAMAMHS']."</namamhs>";
echo "<alamat>".$data['ALAMAT']."</alamat>";
echo "</mhs>";
}
echo '</hasil>';
?>
請幫我解決這個腳本。 search.php上的XML已經在運行,但我的搜索沒有。任何幫助表示讚賞。
Ankur,這是一個TON代碼,用於在現代JS庫中執行一行代碼。我的建議是使用jQuery:http://jqapi.com/#p=jQuery.post – ladieu
