Jquery 插件防刷新 60秒倒计时
//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="http://apps.bdimg.com/libs/jquery/1.11.1/jquery.min.js" ></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>
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*/
$("#getting").click(function(){
var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/;
var mobile = $("#phone").val();
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");
$("#phone").focus();
return false;
}
var phone=$("#phone").val();
$.ajax({
type: "POST",
url: '<%=basePath%>app/jiguang.do',
data: {phone:phone},
dataType:'json',
cache: false,
success: function(data){
if("success" == data.result){
alert(data.msg_id);
$("#msg_id").val(data.msg_id)
}else{
$("#phone").css("background-color","#D16E6C");
setTimeout("$('#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});
}else {
clearInterval(resend);
btn.val("获取验证码").removeAttr('disabled style');
}
}, 1000);
btn.attr('disabled',true).css('cursor','not-allowed');
});
});
百度云中保存 js文件 jquery.cookie.js
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
