轉載自：https://www.cnblogs.com/liaohongwei/p/9717511.html
1. onclick=name()
<!DOCTYPE html>
<html leng="en">
<head>
<meta charset="utf-8">
<title>one</title>
</head>
<body>
<div id="dome"></div>
<button type="button" onclick="displayDate()">點擊</button>
<script>
function displayDate(){
document.getElementById("dome").innerHTML=Date();
}
</script>
</body>
</html>
2. js中綁定
<!DOCTYPE html>
<html leng="en">
<head>
<meta charset="utf-8">
<title>one</title>
</head>
<body>
<div id="dome"></div>
<button type="button">點擊</button>
<script>
var btn=document.getElementById("btn");
btn.onclick=function(){
document.getElementById("dome").innerHTML=Date();
}
</script>
</body>
</html>
3. 事件柄方法
//addEventListener 用於向指定元素添加事件句柄
//可以向一個元素添加多次點擊事件，後一個點擊事件不會覆蓋前一個點擊事件
<!DOCTYPE html>
<html leng="en">
<head>
<meta charset="utf-8">
<title>one</title>
</head>
<body>
<div id="dome"></div>
<button type="button">點擊</button>
<script>
var btn=document.getElementById("btn");
btn.addEventListener('click',function(){
document.getElementById("dome").innerHTML=Date();
},false)
</script>
</body>
</html>
