javascript - HTML 表单提交弹出窗口

Question

我的网站上有一个 HTML 表单。当我填写它并单击提交时，我的操作端点工作正常。我想用它做以下事情。单击提交时:

1. 将表单数据发布到操作端点
2. 用按钮覆盖感谢消息，或者可能只是一条在几秒钟后消失的消息
3. 一旦覆盖消失，我希望表单被清除，但用户返回到同一页面。

我的基本形式是这样的:

<form method="post" action="https://mywebsite.com/formdata">
<div class="fields">
    <div class="field half">
        <input type="text" name="name" id="name" placeholder="Name" />
    </div>
    <div class="field half">
        <input type="email" name="email" id="email" placeholder="Email" />
    </div>
    <div class="field">
        <textarea name="message" id="message" placeholder="Message"></textarea>
    </div>
</div>
<ul class="actions">
    <li><input type="submit" value="Send" class="primary" /></li>
</ul>

我尝试通过从我发现的一些在线指南中添加覆盖代码来修改代码，如下所示:

<form method="post" action="https://mywebsite.com/formdata">
<div class="fields">
    <div class="field half">
        <input type="text" name="name" id="name" placeholder="Name" />
    </div>
    <div class="field half">
        <input type="email" name="email" id="email" placeholder="Email" />
    </div>
    <div class="field">
        <textarea name="message" id="message" placeholder="Message"></textarea>
    </div>
</div>
<ul class="actions">
    <li><input class="trigger_popup_fricc" type="submit" value="Send" class="primary" /></li>
</ul>
<div class="hover_bkgr_fricc">
    <span class="helper"></span>
    <div>
        <div class="popupCloseButton">X</div>
        <p>Add any HTML content<br />inside the popup box!</p>
    </div>
</div>                                  

添加了在提交按钮上添加的类及其下方的悬停弹出 div。然后添加的 CSS 是:

    /* Popup box BEGIN */
.hover_bkgr_fricc{
    background:rgba(0,0,0,.4);
    cursor:pointer;
    display:none;
    height:100%;
    position:fixed;
    text-align:center;
    top:0;
    width:100%;
    z-index:10000;
}
.hover_bkgr_fricc .helper{
    display:inline-block;
    height:100%;
    vertical-align:middle;
}
.hover_bkgr_fricc > div {
    background-color: #fff;
    box-shadow: 10px 10px 60px #555;
    display: inline-block;
    height: auto;
    max-width: 551px;
    min-height: 100px;
    vertical-align: middle;
    width: 60%;
    position: relative;
    border-radius: 8px;
    padding: 15px 5%;
}
.popupCloseButton {
    background-color: #fff;
    border: 3px solid #999;
    border-radius: 50px;
    cursor: pointer;
    display: inline-block;
    font-family: arial;
    font-weight: bold;
    position: absolute;
    top: -20px;
    right: -20px;
    font-size: 25px;
    line-height: 30px;
    width: 30px;
    height: 30px;
    text-align: center;
}
.popupCloseButton:hover {
    background-color: #ccc;
}
.trigger_popup_fricc {
    cursor: pointer;
    font-size: 20px;
    margin: 20px;
    display: inline-block;
    font-weight: bold;
}
/* Popup box BEGIN */   

添加的 javascript 是:

    $(window).load(function () {
    $(".trigger_popup_fricc").click(function(){
       $('.hover_bkgr_fricc').show();
    });
    $('.hover_bkgr_fricc').click(function(){
        $('.hover_bkgr_fricc').hide();
    });
    $('.popupCloseButton').click(function(){
        $('.hover_bkgr_fricc').hide();
    });
});

但它不起作用。没有弹出窗口。非常感谢任何有关如何完成我想完成的任务的指导。

您只需要向 url enpoint 添加一个 ajax 请求并获取响应。但是正如在另一个答案中提到的，您需要使用 preventDefault() 来避免在单击发送按钮时刷新。

这是相同的 jsfiddle - https://jsfiddle.net/ekLys4qa/1/

$(".trigger_popup_fricc").click(function(e){
  e.preventDefault();
  var my_inputs = {
    name: $("#name").val(),
    email: $("#email").val(),
    message: $("#message").val()
  }
  $.ajax({
    type: "POST",
    url: "https://httpbin.org/post", // change it to your application specific url
    data: my_inputs,
    success: function(data, status){
    	console.log(data);
      console.log(status);
      $('.hover_bkgr_fricc').show();
    },
    error: function(err){
    	console.log(err);
    }
  });
  // for resetting the form
  $("#name").val("");
  $("#email").val("");
  $("#message").val("");
});

$('.popupCloseButton').click(function(){
  $('.hover_bkgr_fricc').hide();
});

   /* Popup box BEGIN */
.hover_bkgr_fricc{
    background:rgba(0,0,0,.4);
    cursor:pointer;
    display:none;
    height:100%;
    position:fixed;
    text-align:center;
    top:0;
    width:100%;
    z-index:10000;
}
.hover_bkgr_fricc .helper{
    display:inline-block;
    height:100%;
    vertical-align:middle;
}
.hover_bkgr_fricc > div {
    background-color: #fff;
    box-shadow: 10px 10px 60px #555;
    display: inline-block;
    height: auto;
    max-width: 551px;
    min-height: 100px;
    vertical-align: middle;
    width: 60%;
    position: relative;
    border-radius: 8px;
    padding: 15px 5%;
}
.popupCloseButton {
    background-color: #fff;
    border: 3px solid #999;
    border-radius: 50px;
    cursor: pointer;
    display: inline-block;
    font-family: arial;
    font-weight: bold;
    position: absolute;
    top: -20px;
    right: -20px;
    font-size: 25px;
    line-height: 30px;
    width: 30px;
    height: 30px;
    text-align: center;
}
.popupCloseButton:hover {
    background-color: #ccc;
}
.trigger_popup_fricc {
    cursor: pointer;
    font-size: 20px;
    margin: 20px;
    display: inline-block;
    font-weight: bold;
}
