通过ajax提交多种表格

Question

I'm trying to submit multiple forms thru ajax post, but the problem is the server returns an empty array in post.

Here are the codes in my JS:

$('#check_test').click(function(e){
    e.preventDefault();
    e.stopPropagation();

    var results = [];
    $('form').each(function(){
        results.push($(this).serialize());
    });

    $.ajax({
        'url': 'handler/test_handler.php',
        'method': 'POST',
        'data': JSON.stringify(results),
        'dataType': 'html',
        'success': function (data) {
            console.log(data);
        }
    });
});

In server side:

var_dump(json_decode($_POST)); // null
var_dump($_POST); // empty array

What am I doing wrong? Thanks!

No, there is no method attribute, its type :

$.ajax({
    'url': 'handler/test_handler.php',
    'type': 'POST', // type not method
    'data': {data: JSON.stringify(results)},
    'dataType': 'html',
    'success': function (data) {
        console.log(data);
    }
});

method is the attribute used in your <form> tags.

Sample Output

Sidenote: I think serializeArray() is much more suitable:

results.push($(this).serializeArray());
