这里写图片描述

先到官网（http://plugins.jquery.com/）下载jquery.cookie.js插件，放到相应文件夹，代码如下：

    <style type="text/css">

        .captcha-box {width: 360px; height: 34px; margin: 30px; padding: 30px; border: #956E6F 1px dashed; border-radius: 5px; background-color: #FAF2F2;}
        #mobile { float: left; width: 180px; height: 32px; border: #e5e5e5 1px solid; line-height: 32px; text-indent: 8px; outline: none;}
        #getting {float: left; height: 34px; margin-left: -1px; padding: 0 18px; text-align: center;  line-height: 34px; border: #e5e5e5 1px solid; background: linear-gradient(0deg, #f4f2f2 0%,#fbf9f9 100%); cursor: pointer; outline: none;}
    </style>
    <script>
        $(function(){

            /*防刷新：检测是否存在cookie*/
            if($.cookie("captcha")){
                var count = $.cookie("captcha");
                var btn = $('#getting');
                btn.val(count+'秒后可重新获取').attr('disabled',true).css('cursor','not-allowed');
                var resend = setInterval(function(){
                    count--;
                    if (count > 0){
                        btn.val(count+'秒后可重新获取').attr('disabled',true).css('cursor','not-allowed');
                        $.cookie("captcha", count, {path: '/', expires: (1/86400)*count});
                    }else {
                        clearInterval(resend);
                        btn.val("获取验证码").removeClass('disabled').removeAttr('disabled style');
                    }
                }, 1000);
            }

            /*点击改变按钮状态，已经简略掉ajax发送短信验证的代码*/
            $('#getting').click(function(){
                var btn = $(this);
                var count = 60;
                var resend = setInterval(function(){
                    count--;
                    if (count > 0){
                        btn.val(count+"秒后可重新获取");
                        $.cookie("captcha", count, {path: '/', expires: (1/86400)*count});
                    }else {
                        clearInterval(resend);
                        btn.val("获取验证码").removeAttr('disabled style');
                    }
                }, 1000);
                btn.attr('disabled',true).css('cursor','not-allowed');
            });

        });
</script>
