I am currently trying to use a Ajax in netbeans using JavaScript and PHP file. The following code I should click the button and the contents of the php fill should appear but it doesn't. When I use firebug in firefox the response shows the full php file has returned but will not display on webpage. Why???
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<script>
function getXMLHttp() {
var xmlHttp
try {
//Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest();
}
catch (e) {
//Internet Explorer
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {
alert("Your browser does not support AJAX!")
return false;
}
}
}
return xmlHttp;
}
function MakeRequest() {
var xmlHttp = getXMLHttp();
xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4) {
HandleResponse(xmlHttp.responseText);
}
}
xmlHttp.open("GET", "ajax.php", true);
xmlHttp.send(null);
}
function HandleResponse(response) {
document.getElementById('ResponseDiv').innerHTML = response;
}
</script>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<input type='button' onclick='MakeRequest();' value='Use AJAX!!!!'/>
<div id='ResponseDiv'>
This is a div to hold the response.
</div>
</body>
</html>
My PHP file is
<?php
echo "This is a php response to your request!!!!!!";
?>
Apart from the fact that HTML code is barely decent, why not use jQuery?
<button id="get" onClick="return false;">jQuery get</button>
<div id="result"></div>
<script type="text/javascript">
$("#get").click(function() {
$.get( "ajax.php", function( data ) {
$( "#result" ).html( data );
});
});
</script>
PHP is server side and is not made to be run on the client side. Your response should come from a URL and not the contents of a file. Ensuring that your response contains on HTML and not PHP should lead you to your solution.
Try replacing your PHP file with <p>This is a php response to your request!!!!!!</p>
If this enables you to show your content, you have your problem and solution.
