廢話少說,直接上代碼:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>按鈕5秒后可以點擊</title>
<script type="text/javascript" src="js/jquery.min.js">
</script>
<script >
setTimeout(function(){
$("button[name = 'btn']").removeAttr("disabled");
},5000);
</script>
</head>
<body>
<div>
<button name="btn" disabled>同意</button>
</div>
</body>
</html>
在按鈕上實現倒計時效果:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>按鈕倒數5秒后才能點擊</title>
</head>
<!--<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>-->
<script src="js/jquery-2.1.1.min.js"></script>
<body>
<button type="button" id="test" disabled>點擊(5)</button>
</body>
<script type="text/javascript">
var i=5;
var timehwnd=setInterval("Countdown()",1000);
function Countdown(){
i--;
if(i == 0){
$("button[id='test']").html("點擊");
$("button[id='test']").removeAttr("disabled");
clearInterval(timehwnd);
}else{
$("button[id='test']").html("點擊("+i+")");
}
}
</script>
</html>
