我试图制作一个简单的按钮，它可以在鼠标悬停时使用 JavaScript 改变颜色，但它不起作用，请帮忙.... HTML:
<head lang="en">
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="Button.css" />
<script type="text/javascript" src="Button.js"></script>
<title>BUTTON</title>
</head>
<body>
<div id="Button">PRESS ME</div>
</body>
JavaScript:
var Button = document.getElementById('Button');
Button.onmouseover(function(){
this.style.backgroundColor = 'rgba(0,255,0,0.3)';
});
CSS:
#Button{
width: 120px;
height : 30px;
position: fixed;
top: 100px;
left:300px;
border: 1px solid black;
background-color : rgba(0,0,255,0.3);
font-size : 25px;
}
最佳答案
改变
Button.onmouseover(function(){
this.style.backgroundColor = 'rgba(0,255,0,0.3)';
});
到
Button.onmouseover = function(){
this.style.backgroundColor = 'rgba(0,255,0,0.3)';
};
完整示例:
var Button = document.getElementById('Button');
Button.onmouseover = function () {
this.style.backgroundColor = 'rgba(0,255,0,0.3)';
};#Button {
width: 120px;
height : 30px;
position: fixed;
top: 100px;
left:300px;
border: 1px solid black;
background-color : rgba(0, 0, 255, 0.3);
font-size : 25px;
}<div id="Button">PRESS ME</div>JSFiddle 演示:http://jsfiddle.net/n4j53jcu/
