javascript - 无法在 /script.js:13:15 处读取未定义的属性“样式”
问题描述
为什么它不计算样式并写入错误,我该如何解决?似乎他正确指示了所有路径,连接了样式和脚本,但他要么根本不阅读它们(样式),要么显示这样的错误。这是代码html,javascript,css。你怎么能解决这个错误?总的来说不是这样吗?
html:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="style.css">
<script src = "script.js">
</script>
<TITLE></TITLE>
</head>
<body>
<div class="cookie_notice">
This site uses cookies
<div>
<a class="cookie_btn" id="cookie_close" href="#close">Agree</a>
<a class="cookie_btn" href="#politika">privacy policy</a>
</div>
</div>
</body>
</html>
JS:
function getCookie(name) {
let matches = document.cookie.match(new RegExp(
"(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
));
return matches ? decodeURIComponent(matches[1]) : undefined;
}
let cookiecook = getCookie("cookiecook"),
cookiewin = document.getElementsByClassName('cookie_notice')[0];
if (cookiecook != "no") {
cookiewin.style.display="block";
document.getElementById("cookie_close").addEventListener("click", function(){
cookiewin.style.display="none";
let date = new Date;
date.setDate(date.getDate() + 1);
document.cookie = "cookiecook=no; path=/; expires=" + date.toUTCString();
});
}
CSS:
.cookie_notice {
display: none;
position: fixed;
z-index: 9999999;
bottom: 0;
left: 0;
right: 0;
text-align: center;
font-size: 15px;
font-family: Verdana, sans-serif;
color: #FFF;
background: #337AB7;
padding: 10px 20px;
border-top: 4px solid #BFE2FF;
}
.cookie_btn {
display: inline-block;
margin: 10px 6px 4px 6px;
text-decoration: none;
position: relative;
font-size: 13px;
padding: 4px 12px;
color: #FFF;
font-weight: bold;
text-transform: uppercase;
background: #337AB7;
border: 2px solid #BFE2FF;
}
.cookie_btn:hover {
color: #FFF;
}
.cookie_btn:after,
.cookie_btn:before {
position: absolute;
height: 2px;
left: 50%;
background: #FFF;
bottom: -6px;
content: "";
transition: all 280ms ease-in-out;
width: 0;
}
.cookie_btn:before {
top: -6px;
}
.cookie_btn:hover:after,
.cookie_btn:hover:before {
width: 100%;
left: 0;
}
解决方案
你为什么不尝试在底部制作标签。像这样:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="style.css">
<TITLE></TITLE>
</head>
<body>
<div class="cookie_notice">
This site uses cookies
<div>
<a class="cookie_btn" id="cookie_close" href="#close">Agree</a>
<a class="cookie_btn" href="#politika">privacy policy</a>
</div>
</div>
<script src = "script.js">
</script>
</body>
</html>
干得好
