Jquery插件实现点击获取验证码后60秒内禁止重新获取_jquery

效果图：

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：

代码如下:












$(function(){
/*仿刷新：检测是否存在cookie*/
if($.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: (1/800)*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: (1/800)*count});
}else {
clearInterval(resend);
btn.val("获取验证码").removeAttr('disabled style');
}
}, 1000);
btn.attr('disabled',true).css('cursor','not-allowed');
});
});
