AJAX传递给PHP错误

Question

I am passing serialized data and a variable as well to php, but i am getting an unexpected token '(' error in the data section

if i take out the 'lid':userID from the data section, it works fine.

$("#cname").submit(function (e) {
    e.preventDefault();
    $.ajax({
        url: 'someurl',
        crossDomain: true,
        type: 'post',
        data: {$("#cname").serialize(), 'lid':userID},
        success: function (data) {
            $("#result").html(data);
            $.mobile.changePage($('#page-tasklist'));
        },
    });
});

The output of the .serialize() method is a string like action=login&UserName=&Password=&Site=Test. So try this instead.

$("#cname").submit(function (e) {
    e.preventDefault();
    $.ajax({
        url: 'someurl',
        crossDomain: true,
        type: 'post',
        data: $("#cname").serialize() + '&lid=' + userID,
        success: function (data) {
            $("#result").html(data);
            $.mobile.changePage($('#page-tasklist'));
        },
    });
});

Also, if you just remove lid: userID from your ajax request, you would actually still get an error because {$("#cname").serialize()} is not valid json. The data parameter can accept either an encoded string like what .serialize() returns or a json object.

The following 2 examples are equivalent:

$.ajax({url:'index.php',type:'POST',data:{z:1,y:2}});
$.ajax({url:'index.php',type:'POST',data:'x=1&y=2'});
