本文給大家分享一段js代碼關于實現(xiàn)驗證碼功能并在60秒后倒計時功能。廢話不多說了，具體代碼如下所示：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<meta content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=no" id="viewport" name="viewport">
<title></title>
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
var countdown=60;
function settime(obj) {
if (countdown == 0) {
obj.removeAttribute("disabled");
obj.value="免費獲取驗證碼";
countdown = 60;
return;
} else {
obj.setAttribute("disabled", true);
obj.value="重新發(fā)送(" + countdown + ")";
countdown--;
}
setTimeout(function() {
settime(obj) }
,1000)
}
</script>
<body>
<input type="button" id="btn" value="免費獲取驗證碼" onclick="settime(this)" />
</body>
