xmlHTTPrequest – no response from server

Hi, I am running the scripts below which should return a string containing a URL.
So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as [I]?Location=[/I]. It won’t work at all in IE.

Can any one help?
This is the form:

[code=html]
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>

<script src=”calendar1.js” type=”text/javascript”></script>
<link href=”calendar.css” type=”text/css” rel=”stylesheet” />
<style>
#container {

}

}
</style>

<body>
<script language=”javascript” type=”text/javascript”>

//Browser Support Code
function ajaxFunction(){
var ajaxRequest; // The variable that makes Ajax possible!

try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject(“Msxml2.XMLHTTP”);
} catch (e) {
try{
ajaxRequest = new ActiveXObject(“Microsoft.XMLHTTP”);
} catch (e){
// Something went wrong
alert(“Your browser broke!”);
return false;
}
}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4 && ajaxRequest.status==200){
document.getElementById(“output”).innerHTML=ajaxRequest.responseText;
}
}
ajaxRequest.open(“GET”, “text.php”, true);
ajaxRequest.send(null);
}

<input name=”wknd” type=”radio” value=”MTWHF” />No

</td>
</tr>
</table>

</form>
Your query reads:<span id=”output”></span>

</div>
</div>
</body>
</html>[/code]

and this is the PHP:

[code=php][/code]

<?php
// details sent from form

$area=$_GET[“area”];
$sdate=$_GET[“date”];
$fdate=$_GET[“date”];
$wkend=$_GET[“wkend”];

// process
$area = “?Location=”.$area;
$sdate = “&AfterDate=”.$sdate;
$fdate = “&BeforeDate=”.$fdate;
$wkend = “&Days=”.$wkend;

// construct text
$common = “http://www.brew.co.uk/SessionSearcher/ShowResults.aspx”;
$sweep = $common.$area.$sdate.$fdate.$wkend;
echo $sweep;
?>[/code]

@tirnaMay 06.2010 — I suspect your form data is not being passed to your ajax function using

[COLOR=#ff8000][code=php]
<form method="get" name="formdata" id="formdata" onChange="ajaxFunction();">
[/code]


[COLOR=black]If you haven't already done so, check if the form data is being passed to ajaxFunction() using alert() and then onto text.php using echo statements or a debugger.[/COLOR]

[COLOR=#000000][/COLOR]

[COLOR=#000000]You just need to do some basic debugging 101 to find the source of the problem.[/COLOR]

Success!
