 <a id="submit" class="link_ok" href="javascript:;">确定</a>

$(function() {
            $('#submit').click(function() {

                var x = $('form').serializeArray();
                var m = [], idata;

                $.each(x, function(i, field){
                    m.push('"' + field.name + '":"' + field.value + '"');
                });
                idata ='{' +  m.join(',') + '}';
                idata = eval('(' +idata+ ')');

                $.ajax({
                    url:'index.php?act=address&user_id=<?php echo $user_id;?>',
                    type:'post',
                    data:idata,
                    dataType:'json',
                    success:function(res){
                        console.log(res);
                        if (res.code == 1) {
                            window.location.href='index.php?act=index&user_id=<?php echo $user_id;?>';
                        }else{
                           layer.msg(res.msg);
