[英]using customize slider on Joomla its working fine on my machine giving trouble on hosting
[英]Ajax is not working on my customize component in joomla
我在joomla文章中遇到了问题,该文章使用Sourcerer自定义了代码。
这是我的一些有关ajax javascript的示例代码:
<script type="text/javascript">
function showBox1(element) {
document.getElementById('hideBox1').style.display = "";
if (element == "")
{
document.getElementById("txtHint").innerHTML = "";
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("txtHint").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "home/matedis/public_html/joomla/Add_Edit_Intake/getuser.php?q=" + element, true);
xmlhttp.send();
}
</script>
将值传递给函数的代码在这里:
<?php
// Get default database object
$db = JFactory::getDBO();
// Get a new JDatabaseQuery object
$query = $db->getQuery(true);
// Build the query
$query->select($db->quoteName('campusid'));
$query->from($db->quoteName('campus'));
$query->where($db->quoteName('collegeid') . '=' . $db->quote('1'));
// Set the query for the DB oject to execute
$db->setQuery($query);
// Get the DB object to load the results as a list of objects
$results = $db->loadObjectList();
if ($results) {
foreach ($results as $result) {
echo "<label class='option block spacer-t10'>";
echo "<input type='radio' id ='campusID' name='campusID' value='$result->campusid' onChange='showBox1(this.value)'><span class='radio'></span>";
echo $result->campusid;
echo '</label>';
}
} else {
echo 'Error';
}
?>
这是我的getuser.php代码:
<?php
$q = intval($_GET['q']);
define( 'JPATH_BASE', $_SERVER[ 'DOCUMENT_ROOT' ] ); // define JPATH_BASE on the external file
require_once( JPATH_BASE . DS . 'libraries' . DS . 'import.php' ); // framework
require_once( JPATH_BASE . DS . 'configuration.php' ); // config file
$db = JFactory::getDBO();
$sql="SELECT courseid FROM course WHERE campusid = '".$q."'";
// Build the query
$query->select($db->quoteName('courseid'));
$query->from($db->quoteName('course'));
$query->where($db->quoteName('campusid').'='. $db->quote($q)); //This later must change to retrieve id from current user
// Set the query for the DB oject to execute
$db->setQuery($query);// Get the DB object to load the results as a list of objects
$results = $db->loadObjectList();
if($results){
foreach($results as $result)
{
echo $result->courseid;
}
}
else{ echo 'Error';}
?>
我犯了什么错误吗? 因为它没有显示输出,所以我希望从这里http://www.w3schools.com/php/php_ajax_database.asp参考代码。 抱歉造成任何不便,因为我还是joomla和php ajax的新手。
xmlhttp.open("GET","home/matedis/public_html/joomla/Add_Edit_Intake/getuser.php?q="+element,true);
这是public_html的真实路径吗? 没有..
