通过jquery.cookie.js插件可以快速实现“点击获取验证码后60秒内禁止重新获取（防刷新）”的功能
先到官网（http://plugins.jquery.com/cookie/ ）下载cookie插件，放到相应文件夹，代码如下：
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="utf-8">
- <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
- <title>Examples</title>
- <meta name="description" content="">
- <meta name="keywords" content="">
- <script src="<a href="http://apps.bdimg.com/libs/jquery/1.11.1/jquery.min.js" target="_blank" <a="">http://apps.bdimg.com/libs/jquery/1.11.1/jquery.min.js</a> " ></script>
- <script src="jquery.cookie.js" ></script>
- <style type="text/css">
- * {margin: 0; padding: 0; font-family: "Microsoft Yahei";}
- .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>
- $(function(){
- /*仿刷新：检测是否存在cookie*/
- if($.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>
- </head>
- <body>
- <div class="captcha-box">
- <input type="text" id="mobile" maxlength="11" placeholder="请输入手机号码">
- <input type="button" id="getting" value="获取验证码">
- </div>
- </body>
- </html>
