//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：

我的应用实例

    <script type="text/javascript">

	$(function(){
        /*仿刷新：检测是否存在cookie*/
         if($.cookie("captcha")){
            var count = $.cookie("captcha");
            var btn = $(‘#getting‘);
            btn.val(count+‘秒后重新获取‘).attr(‘disabled‘,true).css(‘cursor‘,‘not-allowed‘);
            var resend = setInterval(function(){
                count--;
                if (count > 0){
                    btn.val(count+‘秒后重新获取‘).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*/
        $("#getting").click(function(){
        	var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/;

 	      	 alert(mobile);
 			if(!myreg.test(mobile)) 
 			{ 
 			    alert(‘请输入有效的手机号码！‘); 
 				$("#phone").focus();
 			    return false; 
 			}
 			if(mobile==""){
 				alert("手机号码不为空");

 			}
 			 var phone=$("#phone").val();
			 $.ajax({

		 					setTimeout("$(‘#phone‘).val(‘此用户名已存在!‘)",500);
		 				 }
		 			}
		 		});
			 
			    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});

        });

    });

按照流程输入了正确信息却没有相应的显示效果，是因为：  js文件发生了冲突  删掉报错的js以后项目完美运行
