jQuery ajax无法检索json

Question

So here is the ajax call that is making the problem

$.ajax({
    type: "POST",
    url: "src/login.php",
    dataType: "JSON",
    data: {username: usr, password: pwd},
    success: function(json){
        loggedStatus=json.status;
        alert(json.status);
    }
});

It is succesfully passing the variables to the php file, but it isn't entering th success: part. This is example of what the php file returns

{
    "status": "Wrong"
}

or

{
    "status": "154414707fe8d22bb6239648ce11a9c9bede1a3e"
}

Which is totaly fine.

Answer 1

Try putting the url as the first parameter in your $.ajax({ function.

because the syntax is: $.ajax(url[, options])
