我得到了以下信息:

formSubmit('#login-form', '/api/user/login', '/members/');

在哪里

function formSubmit(form, url, target) {
    $(form).submit(function(event) {
        $.post(url, $(form).serialize())
            .done(function(res) {
                if (res.success) {
                    window.location = target;
                }
                else {
                    alert(res.error);
                }
            })
            .fail(function(res) {
                alert("Server Error: " + res.status + " " + res.statusText);

            })
        event.preventDefault();
    });
}

这假设post到'url'返回一个ajax形式的{success: false, error:'my error to display'}

你可以随意改变。请随意使用该片段。

考虑使用最接近的

$('table+table form').closest('tr').filter(':not(:last-child)').submit(function (ev, frm) {
        frm = $(ev.target).closest('form');
        $.ajax({
            type: frm.attr('method'),
            url: frm.attr('action'),
            data: frm.serialize(),
            success: function (data) {
                alert(data);
            }
        })
        ev.preventDefault();
    });

这是一个简单的参考:

// this is the id of the form
$("#idForm").submit(function(e) {

    e.preventDefault(); // avoid to execute the actual submit of the form.

    var form = $(this);
    var actionUrl = form.attr('action');
    
    $.ajax({
        type: "POST",
        url: actionUrl,
        data: form.serialize(), // serializes the form's elements.
        success: function(data)
        {
          alert(data); // show response from the php script.
        }
    });
    
});

JavaScript

(function ($) {
    var form= $('#add-form'),
      input = $('#exampleFormControlTextarea1');


   form.submit(function(event) {

       event.preventDefault(); 

       var req = $.ajax({
           url: form.attr('action'),
           type: 'POST',
           data: form.serialize()
       });
    req.done(function(data) {
       if (data === 'success') {
           var li = $('<li class="list-group-item">'+ input.val() +'</li>');
            li.hide()
                .appendTo('.list-group')
                .fadeIn();
            $('input[type="text"],textarea').val('');
        }
   });
});


}(jQuery));

HTML

    <ul class="list-group col-sm-6 float-left">
            <?php
            foreach ($data as $item) {
                echo '<li class="list-group-item">'.$item.'</li>';
            }
            ?>
        </ul>

        <form id="add-form" class="col-sm-6 float-right" action="_inc/add-new.php" method="post">
            <p class="form-group">
                <textarea class="form-control" name="message" id="exampleFormControlTextarea1" rows="3" placeholder="Is there something new?"></textarea>
            </p>
            <button type="submit" class="btn btn-danger">Add new item</button>
        </form>

Try

fetch(form.action,{method:'post', body: new FormData(form)});

function send(e,form) { fetch(form.action,{method:'post', body: new FormData(form)}); console.log('We submit form asynchronously (AJAX)'); e.preventDefault(); } <form method="POST" action="myapi/send" onsubmit="send(event,this)" name="orderproductForm"> <input hidden name="csrfToken" value="$0meh@$h"> <input name="email" value="aa@bb.com"> <input name="phone" value="123-456-666"> <input type="submit"> </form> Look on Chrome Console > Network after/before 'submit'

你可以使用Ajax Form Plugin或jQuery serialize函数中的ajaxForm/ajaxSubmit函数。

AjaxForm：

$("#theForm").ajaxForm({url: 'server.php', type: 'post'})

or

$("#theForm").ajaxSubmit({url: 'server.php', type: 'post'})

当按下提交按钮时，ajaxForm将发送。ajaxSubmit立即发送。

序列化:

$.get('server.php?' + $('#theForm').serialize())

$.post('server.php', $('#theForm').serialize())
