Question

这里我想让鼠标悬停在链接文本上，因为我已经应用了属性x.style.fontsize =＆＃34; 40px＆＃34 ;;但是无法这样做。我想弄清楚这有什么问题，我该怎么办？?????????

<script>
function big(x){
x.style.color = "red";
x.style.fontsize = "40px";
}
function small(x){
x.style.color = "white";
x.style.fontsize =20px;}

</script>
<meta http-equiv="content-Type" content="text/html; charset=utf-8" />
<link rel= "stylesheet" href="stylesheets/screen.css" type="text/css" media="screen" />
</head>
<body>

Answer 1

你不需要JS。你可以使用CSS：

a{
  font-size:20px;
}
a:hover{
  font-size:40px;
}

使用JS编辑非单字CSS规则时，需要使用camelCase：

x.style.fontSize:40px;

注意资本S

Answer 2

试试这个：

x.style.fontSize = "20px";

有大写字母 - fontSize

脚本标记为

<script type="text/javascript">
