The javascript password verification code is as follows

  <script src="js/jquery-1.11.1.js"></script>
  <script>
    $(function(){
      $(document).on('blur','input',function(){
        var $password=$('#password').val();
        var $password_again=$('#password_again').val();
          if(!$password){
            $("#password").addClass('redBorder').next('label').show().html('不能为空');;
            return false;
          }else if(!$password_again){
            $("#password_again").addClass('redBorder').next('label').show().html('不能为空');
            return false;
          }else{
            $('input').removeClass('redBorder').next('label').empty();
            if($password_again==$password){
              $("#password,#password_again").next('label').show().html('两次密码一致').addClass('valid');
            }else if($password_again!=$password){
              $("#password,#password_again").addClass('redBorder').next('label').show().html('两次密码不一致').removeClass('valid').addClass('erro');
            }
 
        } 
      })
       
    })
  </script>
  <style>
    .redBorder{
      border: 1px solid red;
    }
    .erro{
      background: url('images/unchecked.gif') no-repeat;
      padding-left: 16px;
    }
    .valid{
      background: url('images/checked.gif') no-repeat;
      width: 16px;
      height: 16px;
    }
