在自动完成属性关闭时实现类似自动完成的功能,可以通过自定义JavaScript代码来实现。以下是一个基础的实现思路和相关概念:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Custom Autocomplete</title>
<style>
.autocomplete-items {
position: absolute;
border: 1px solid #d4d4d4;
border-bottom: none;
border-top: none;
z-index: 99;
top: 100%;
left: 0;
right: 0;
}
.autocomplete-items div {
padding: 10px;
cursor: pointer;
background-color: #fff;
border-bottom: 1px solid #d4d4d4;
}
.autocomplete-items div:hover {
background-color: #e9e9e9;
}
</style>
</head>
<body>
<input type="text" id="autocompleteInput" placeholder="Type to search...">
<div class="autocomplete-items" id="autocompleteList"></div>
<script src="autocomplete.js"></script>
</body>
</html>
const data = [
"Apple", "Banana", "Cherry", "Date", "Elderberry", "Fig", "Grape", "Honeydew"
];
document.getElementById('autocompleteInput').addEventListener('input', function(e) {
const inputVal = e.target.value.toLowerCase();
const autocompleteList = document.getElementById('autocompleteList');
autocompleteList.innerHTML = ''; // Clear previous results
if (inputVal.length > 0) {
const matches = data.filter(item => item.toLowerCase().includes(inputVal));
matches.forEach(match => {
const div = document.createElement('div');
div.textContent = match;
div.addEventListener('click', function() {
document.getElementById('autocompleteInput').value = match;
autocompleteList.innerHTML = ''; // Clear results on selection
});
autocompleteList.appendChild(div);
});
}
});
通过上述方法,即使自动完成功能被关闭,也可以通过自定义脚本实现类似的功能,提升用户体验。
