如何创建弹出表单

步骤 1) 添加 HTML

使用 <form> 元素来处理输入。您可以在我们的网站中了解更多相关信息PHP教程。

示例

<button class="open-button" onclick="openForm()">Open Form</button>


<div class="form-popup" id="myForm">
<form action="/action_page.html" class="form-container">
    <h1>Login</h1>

    <label for="email"><b>Email</b></label>
    <input type="text" placeholder="Enter Email" name="email" required>

    <label for="psw"><b>Password</b></label>
    <input type="password" placeholder="Enter Password" name="psw" required>

    <button type="submit" class="btn">Login</button>
    <button type="button" class="btn cancel" onclick="closeForm()">Close</button>
</form>
</div>

步骤2）添加CSS：

示例

{box-sizing: border-box;}

/* Button used to open the contact form - fixed at the bottom of the page */
.open-button {
background-color: #555;
color: white;
padding: 16px 20px;
border: none;
cursor: pointer;
opacity: 0.8;
position: fixed;
bottom: 23px;
right: 28px;
width: 280px;
}

/* The popup form - hidden by default */
.form-popup {
display: none;
position: fixed;
bottom: 0;
right: 15px;
border: 3px solid #f1f1f1;
z-index: 9;
}

/* Add styles to the form container */
.form-container {
max-width: 300px;
padding: 10px;
background-color: white;
}

/* Full-width input fields */
.form-container input[type=text], .form-container input[type=password] {
width: 100%;
padding: 15px;
margin: 5px 0 22px 0;
border: none;
background: #f1f1f1;
}

/* When the inputs get focus, do something */
.form-container input[type=text]:focus, .form-container input[type=password]:focus {
background-color: #ddd;
outline: none;
}

/* Set a style for the submit/login button */
.form-container .btn {
background-color: #04AA6D;
color: white;
padding: 16px 20px;
border: none;
cursor: pointer;
width: 100%;
margin-bottom:10px;
opacity: 0.8;
}

/* Add a red background color to the cancel button */
.form-container .cancel {
background-color: red;
}

/* Add some hover effects to buttons */
.form-container .btn:hover, .open-button:hover {
opacity: 1;
}

步骤 3) 添加 JavaScript：

示例

function openForm() {
document.getElementById("myForm").style.display = "block";
}

function closeForm() {
document.getElementById("myForm").style.display = "none";
}
