如何在$ .ajax和$ .ajaxSubmit中添加发布参数

Question

I used the ajax method of jquery for my forms. but now I need to add a field to the function.

how can I have my forms fields and my new post parameter.

        var frm = $(n);
        $.ajax({
                type: frm.attr('method'),
                url: frm.attr('action'),
                //contentType:frm.attr('enctype'),
                data: frm.serialize(),
                success: function (data) {
                    $(dataform).html(data);
                    $(des).html('');
                    $("button[type='submit']").attr('disabled',null);
                }
        });

the data parameter should be like this:

data: frm.serialize() + {'foo':'bar'}

thanks in advance.

Answer 1

.serialize()返回一串参数，就像在查询字符串中看到的那样，因此只需加上+ "&foo=bar"

Answer 2

尝试这样的事情

data: frm.serialize()+'&foo=bar',
