我正在从视频教程中学习如何制作自动完成搜索栏。我做了视频所做的一切,但无济于事。我认为问题在于add.EventListener。当我在Chrome中运行代码时,在控制台中显示:
未捕获的TypeError:无法读取null的属性'addEventListener'
代码:
searchInput.addEventListener('keyup', function() {
const input = searchInput.value;
suggestionsPanel.innerHTML = '';
const suggestions = movies.filter(function(movie) {
return movie.name.toUpperCase().startsWith(input);
});
suggestions.forEach(function(suggested){
const div = document.createElement('div');
div.innerHTML = suggested;
suggestionsPanel.appendChild(div);
});
if (input=== ''){
suggestionsPanel='';
} })
这是JavaScript代码,下面是HTML代码,以查看任何错误。
<html>
<head>
<link rel="icon" href="Geofflixlogo.png">
<title>Geofflix</title>
<link rel="stylesheet" href="geofflix.css">
<script src="geofflix.js" type="text/javascript"></script>
</head>
<body>
<div class="header">
<div class="logo">
<a href="index.html">
<img src="Logo.png" height="50">

<div class="navi">
