1,利用settimeout,语法:
setTimeout(/*执行代码*/, /*毫秒*/);每过多少毫秒执行一次代码
<button id="sms">发送验证码</button>每个手机号每日最多发送6次
$("#sms").click(function() {
setTimer();
}); var wait = 60;
function setTimer() {
if (wait == 0) {
$("#sms").attr("disabled", false);
// btn.text = "";
$("#sms").text("免费获取验证码");
wait = 60;
} else {
$("#sms").attr("disabled", true);
// btn.text = wait + "秒后重新获取验证码";
$("#sms").text(wait + "秒后重新获取验证码");
wait--;
setTimeout(function() {
setTimer();
}, 1000)
}
}
2.
var t1=window.setInterval(hello,1000);
window.clearInterval(t1);//去掉定时器
//待续
