代碼一:
{
wait:90,
hsTime:function(that){
if (this.wait == 0) {
$('#hsbtn').removeAttr("disabled").val('重發短信驗證碼');
this.wait = 90;
} else {
var _this = this;
$(that).attr("disabled", true).val('在'+_this.wait+'秒後點此重發');
_this.wait--;
setTimeout(function() {
_this.hsTime(that);
}, 1000)
}
},
}

代碼五:
最近在寫短信發送驗證碼,就寫了個js/jquery倒計時發送驗證碼按鈕
<script language="javascript" src="jquery-1.7.1.min.js"></script>
<input type="button" id="btn" value="免費獲取驗證碼" />
<script type="text/javascript">
var wait=10;
function time(t) {
if (wait == t) {
t.removeAttribute("disabled");
t.value="免費獲取驗證碼";
wait = 10;
} else {
t.setAttribute("disabled", true);
t.value="重新發送(" + wait + ")";
wait--;
setTimeout(function() {
time(t)
},
1000)
}
}
$(document).ready(function(){
$("#btn").click( function () {
time(this);
});
});
</script>
