jQuery实现按钮5秒后可以点击
废话少说,直接上代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>按钮5秒后可以点击</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>
在按钮上实现倒计时效果:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>按钮倒数5秒后才能点击</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>点击(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("点击");
$("button[id='test']").removeAttr("disabled");
clearInterval(timehwnd);
}else{
$("button[id='test']").html("点击("+i+")");
}
}
</script>
</html>
