How to run external php script using phonegap?

Question

I am trying to connect to a remote server and basically run my application off files on that server. I am able to connect to the server but I don't know how to execute the php files on that server. Here's my javascript function on my local directory which connects to the server:

    function test2(){
    $.getJSON("http://sampleserver.com/check.php?var=test&callback=?", {
    success:function(data){
        alert("Working"); }, 
    error: function() { 
    alert("Error"); 
}
});

}

This alerts "Working". Here's my check.php on the remote server:

<?php
echo "hello";
echo $_GET['jsoncallback'];
?>

Why is hello not being printed to the screen? How would I actually execute this script once I am connected?

Answer 1

您的脚本已经在执行，但是您正在执行AJAX调用，只是用您自己的消息发出警报，因此您对响应不做任何事情，响应中将包含您好文本。

Answer 2

Here is just one example:

var url = '/m.profile_msg/0/send/';
var dataString = 'msg_body='+ msg_body;
$.ajax({
    type: "POST",
    url: url,
    data: dataString,
    success: function(data) {
        try {
            //var data = jQuery.parseJSON(data);
            alert(data);
        } catch(e) {
            alert(data);
        }
    }
});

And on the PHP side:

<?php
$xxarray = array('key' => 'value');
echo json_encode($xxarray);
?>

To run remote scripts - try doing your ajax call to a PHP script and have the PHP script shell execute something. But I wouldn't wait for the reply - rather return a status code back to the mobile device saying that the script is running.
