ajax提交表单以后，页面会弹回顶部

Question

基于laravel做的一个表单提交功能，每次填写完表单，点击提交时，会显示提交成功，但页面会弹回到页面顶部，这事为什么？

HTML代码：

<div class="d-flex flex-column justify-content-between align-items-center mb-5">
    <h3 class="contact-text text-uppercase">send us message if you have any questions</h3>
    <div class="d-flex flex-column justify-content-between align-items-center w-75"> 
        <div class="form-group">
            <label for="exampleFormControlInput1">Your Name</label>
            <input type="text" name="name" class="form-control" placeholder="How could we address you?" id="form-name">
        </div>
        <div class="form-group">
            <label for="exampleFormControlInput1">Working Email</label>
            <input type="email" name="email" class="form-control" placeholder="name@example.com" id="form-email"> 
        </div>
        <div class="form-group">
            <label for="exampleFormControlInput1">Cell Phone</label>
            <input type="phone" name="phone" class="form-control" placeholder="+CountryCode ..." id="form-phone">
        </div>
        <div class="form-group">
            <label for="exampleFormControlTextarea1">Your Question</label>
            <textarea class="form-control" name="question" rows="3" placeholder="Please enter your info" id="form-question"></textarea>
        </div>
        <button class="btn btn-outline-primary btn-lg" id="submit-form" onclick="ajaxseed();return false;">Send Message</button>
    </div> 
</div>

JS代码：

// form sublime
function ajaxseed() {
    var name = $('#form-name').val();
    var email = $('#form-email').val();
    var phone = $('#form-phone').val();
    var question = $('#form-question').val();
   
    $.ajax({
        type: "POST",
        url: url,
        data: data,
        headers: {
            'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
        },
        success: function(){
            swal('success', 'We received your advise', 'success');
            $('#form-name').val('');
            $('#form-email').val('');
            $('#form-phone').val('');
            $('#form-question').val('');
        }
    });
};

Answer 1

阻止了表单的默认事件了么？

Answer 2

你的swal函数中做了什么处理？

Answer 3

表单的submit默认事件会自动刷新页面，可能是这个问题
