代码五：
最近在写短信发送验证码，就写了个js/jquery倒计时发送验证码按钮
<script language="javascript" src="jquery-1.7.1.min.js"></script>
<input type="button" id="btn" value="免费获取验证码" />
<script type="text/javascript">
var wait=10;
function time(t) {
if (wait == t) {
t.removeAttribute("disabled");
t.value="免费获取验证码";
wait = 10;
} else {
t.setAttribute("disabled", true);
t.value="重新发送(" + wait + ")";
wait--;
setTimeout(function() {
time(t)
},
1000)
}
}
$(document).ready(function(){
$("#btn").click( function () { time(this);
});
});
</script>
