I am using CakePHP 1.26 and CDN JQuery in this URL: http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js
In a HTML web page, I have these lines of code:
$.ajax({
type: "POST",
url: "http://mywebsite.com/controllers/avail/"+curl,
success: function(data) {
alert(data);}
});
and in the PHP page, I got another few lines of code:
function avail($uname){
$result1=$this->Site1->User->findByusername($uname);
if($result1){
return 1;
}
else{
return 0;
}
}
As you see, the Avail function will return either zero or one. But there was some redundant data returned from the server,
what I saw in the Alert box was somthing like this (rather than 0 or 1): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/开发者_StackOverflow社区xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>my site</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<style type="text/css">

/*PAGE LAYOUT*/

Or in your controller you can set $this->layout = ''; or $this->layout = 'ajax'; and you shouldn't get any other output.
Add the RequestHandler to the $components array of your controller. With that in place, Cake automatically uses the Ajax layout when there is an Ajax request.
It's telling you what's going wrong right?
<title>Missing Method in Controller</title>
So my guess is that Site1 or User does not exist.
The CakePHP returned an error page saying that the method you are invocating doesn't exist...
I suggest to try the URL without jquery, write it in the address bar and make it work...
ajaxFunction(){
$this->layout = 'ajax';
Configure::write('debug', 0);
if (!$this->RequestHandler->isAjax()) {
$this->cakeError('error', array(
array(
'code' => '404',
'name' => __('Page Not Found', true),
'message' => 'The Request URL does not exist on this server',
'title' => __('404', true),
'base' => $this->base,
'url' => $this->here
)
));
exit();
}
$response=array();
//get ur data in this array
$response['result'] = Configure::read('Ajax.success');
$this->set('response',$response);
$this->renderXhrView();
}
