This time I bring to you what are the precautions. The following is a practical case, let’s take a look.
After the countdown time is up, click the recovery button, which is often used to read the agreement:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>阅读协议倒计时</title>
<script>
var tim=9;
function aaa(){
var btnn=document.getElementById("btn");
if(tim<=0)
{
btnn.value="注册";
btnn.disabled="";
}
else
{
btnn.value="请仔细阅读，还剩" +tim+"秒";
tim--;
}
}
setInterval("aaa()",1000);
</script>
</head>
<body>
<textarea style="width: 500px;height: 300px;">
</textarea>
<input type="button" id="btn" value="请仔细阅读，还剩10秒" disabled="disabled" />
</body>
</html>
