• js部分

  • 注意此处要自行引入jquery

<!--发送验证码-->
<script>
    //倒计时
    var countdown=60;
    function settime(val) {
if (countdown == 0) {
    val.removeAttribute("disabled");
    val.value="当即获取";
    countdown = 60;
    return false;
} else {
    val.setAttribute("disabled", true);
    val.value="还剩" + countdown + "s";
    countdown--;
}
setTimeout(function() {
    settime(val);
},1000);
    }

</script>
