  • 表单验证

    第一步:加载验证插件css和js:官网:http://validform.rjboy.cn/

    <link href="<?=base_url('static/css')?>/valid.css">

    valid.css的详细代码如下:
    .Validform_checktip{
    	margin-left:8px;
    	line-height:20px;
    	height:20px;
    	overflow:hidden;
    	color:#999;
    	font-size:12px;
    }
    .Validform_right{
    	color:#71b83d;
    	padding-left:20px;
    	background:url(images/right.png) no-repeat left center;
    }
    .Validform_wrong{
    	color:red;
    	padding-left:20px;
    	white-space:nowrap;
    	background:url(images/error.png) no-repeat left center;
    }
    .Validform_loading{
    	padding-left:20px;
    	background:url(images/onLoad.gif) no-repeat left center;
    }
    .Validform_error{
    	background-color:#ffe7e7;
    }
    #Validform_msg{color:#7d8289; font: 12px/1.5 tahoma, arial, 5b8b4f53, sans-serif; 280px; -webkit-box-shadow:2px 2px 3px #aaa; -moz-box-shadow:2px 2px 3px #aaa; background:#fff; position:absolute; top:0px; right:50px; z-index:99999; display:none;filter: progid:DXImageTransform.Microsoft.Shadow(Strength=3, Direction=135, Color='#999999'); box-shadow: 2px 2px 0 rgba(0, 0, 0, 0.1);}
    #Validform_msg .iframe{position:absolute; left:0px; top:-1px; z-index:-1;}
    #Validform_msg .Validform_title{line-height:25px; height:25px; text-align:left; font-weight:bold; padding:0 8px; color:#fff; position:relative; background-color:#999;
    background: -moz-linear-gradient(top, #999, #666 100%); background: -webkit-gradient(linear, 0 0, 0 100%, from(#999), to(#666)); filter:  progid:DXImageTransform.Microsoft.gradient(startColorstr='#999999', endColorstr='#666666');}
    #Validform_msg a.Validform_close:link,#Validform_msg a.Validform_close:visited{line-height:22px; position:absolute; right:8px; top:0px; color:#fff; text-decoration:none;}
    #Validform_msg a.Validform_close:hover{color:#ccc;}
    #Validform_msg .Validform_info{padding:8px;border:1px solid #bbb; border-top:none; text-align:left;}

    <
    script type="text/javascript" src="http://validform.rjboy.cn/Validform/v5.3.2/Validform_v5.3.2_min.js"></script>

    第二步:初始化设置:

    <script type="text/javascript">
    $(function(){
        //$(".reg").Validform();  //就这一行代码!;
        //修改默认验证成功提示
        $.Tipmsg.r = '';
      //reg_frm为表单id $(
    "#reg_frm").Validform({ tiptype:2, btnSubmit:"#register", btnReset:"#reset" }); }) </script>

    第三步(例子):

    <form id="reg_frm" action="<?=site_url('login/reg')?>" method="post">
      <fieldset>
          <label class="block clearfix">
             <span class="block input-icon input-icon-right">
                <input id="reg_email" name="email" type="email" class="form-control inputxt" ajaxurl="<?=base_url('login/check_user')?>" datatype="*,e" errormsg="请输入正确的邮箱!" nullmsg="邮箱不能为空!" placeholder="邮箱" />
                  <i class="icon-envelope"></i>
               </span>
               <span style="color:red;"></span>
            </label>
    
           <label class="block clearfix">
              <span class="block input-icon input-icon-right">
                  <input id="reg_nick" name="nick" type="text" class="form-control inputxt" datatype="*" errormsg="请输入昵称!" nullmsg="昵称不能为空!" placeholder="昵称" />
                    <i class="icon-user"></i>
               </span>
               <span style="color:red;"></span>
            </label>
    
           <label class="block clearfix">
                <span class="block input-icon input-icon-right">
                <input id="reg_password" name="reg_password" type="password" class="form-control inputxt" datatype="*6-16" errormsg="密码必须为6-16位任意字符!" nullmsg="密码不能为空!"  placeholder="密码" />
                    <i class="icon-lock"></i>
                </span>
                <span style="color:red;"></span>
             </label>
    
             <label class="block clearfix">
                <span class="block input-icon input-icon-right">
                   <input id="reg_repassword" name ="reg_repassword" type="password" class="form-control inputxt" datatype="*6-16" nullmsg="两次密码不一致!" recheck="reg_password" errormsg="两次密码不一致!" placeholder="再输一次" />
                     <i class="icon-retweet"></i>
                 </span>
                 <span style="color:red;"></span>
              </label>
    
              <label class="block">
                <input id="accept" name="ace" type="checkbox" checked="checked" value="1" class="ace" datatype="*" nullmsg="请接受用户协议!" errormsg="请接受用户协议!" />
              
                                                            
             </label>
                                                        
             <div class="space-24"></div>
    
               <div class="clearfix">
                   <button id="reset" type="reset" class="width-30 pull-left btn btn-sm">
                        <i class="icon-refresh"></i>
                          重置
                     </button>
    
                     <button id="register" type="button" class="width-65 pull-right btn btn-sm btn-success">
                          注册
                          <i class="icon-arrow-right icon-on-right"></i>
                     </button>
                  </div>
           </fieldset>
     </form>

     ajax后台处理代码:

        /**
         *验证用户名是否存在
         *@see check_user()
         *@author zrp <zouruiping@infoclouds.net>
         *@version 2014年4月17日14:30:25
         */
        public function check_user(){
            $email = trim($this->input->post('param',true));
            $res = $this->user_model->check_user($email);
            if(!empty($res)){
                $data = array(
                    'info'    => '该邮箱已被注册',
                    'status'=> 'n'  //状态
                );
            }else{
                $data = array(
                    'info'    => '',
                    'status'=> 'y'
                );
            }
            echo json_encode($data);
        }    

     额外功能:

    (1)文件上传 - swfupload
    
    (2)码强度检测 - passwordStrength
    
    (3)日期控件 - datePicker
    
    (4)表单美化 - jqtransform
    时不我待,不负韶华!立刻行动!不吃学习的苦就会吃生活的苦!
