在前端开发中,实现点击按钮弹出输入框的功能,通常可以使用HTML、CSS和JavaScript来完成。下面是一个简单的示例,展示了如何实现这一功能:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>点击弹出输入框</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<button id="openInputBtn">点击输入</button>
<div id="inputModal" class="modal">
<div class="modal-content">
<span id="closeInputBtn" class="close">×</span>
<input type="text" id="userInput" placeholder="请输入内容">
<button id="submitInputBtn">提交</button>
</div>
</div>
<script src="script.js"></script>
</body>
</html>
.modal {
display: none;
position: fixed;
z-index: 1;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgba(0,0,0,0.4);
}
.modal-content {
background-color: #fefefe;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}
document.getElementById('openInputBtn').addEventListener('click', function() {
document.getElementById('inputModal').style.display = 'block';
});
document.getElementById('closeInputBtn').addEventListener('click', function() {
document.getElementById('inputModal').style.display = 'none';
});
document.getElementById('submitInputBtn').addEventListener('click', function() {
var userInput = document.getElementById('userInput').value;
alert('你输入的内容是: ' + userInput);
document.getElementById('inputModal').style.display = 'none';
});
window.addEventListener('click', function(event) {
if (event.target == document.getElementById('inputModal')) {
document.getElementById('inputModal').style.display = 'none';
}
});
