AJAX URL问题…很奇怪

Question

I have a page from which I am trying to make an AJAX call, but it isn't working, and I'm stumped as to why. My call is:

$.ajax({
    type: "GET",
    url: "<relative URL>/index.php?action=x",
    dataType: "JSON"
}).success(function(person) {
    alert(person.name) //alerts naem
});
    return false;
});

and the PHP is:

<? 

if($_GET["action"] == "x"){

    $person = array("name"=>"Jon Doe","Reputation"=>"Good");
    header("Content-Type: application/json");
    echo json_encode($person);
}

?>

I don't THINK the issue is a faulty URL, since it is a c/p of working calls. It seems to me (but I'm not sure) that it chooses to reuse the old 'action-values' from when the source page was loaded originally. For some reason it completely ignores my action-value…?

Any ideas?

Answer 1

Try moving the PHP into its own file rather than the index.php, which I assume is your main PHP file.

$.ajax({
    type: "GET",
    url: "/ajax.php?action=x",
    dataType: "JSON",
    success: function (person) {
       console.log(person.name);
    }
});

This should be a separate file. Call it ajax.php for an example.

<? 
// ajax.php
if($_GET["action"] == "x"){

    $person = array("name"=>"Jon Doe","Reputation"=>"Good");
    die(json_encode($person));
}

?>

Just make sure ajax.php is in the route of your project and this should work. Check the console.log if it doesn't.
