基于jQuery实现表单提交验证

                      var errorMsg = ‘请输入至少6位的用户名’;
                      $parent.append(‘<span class=”formtips onError”>’+errorMsg+'</span>’);
                   }else{
                       var okMsg = ‘输入正确’;
                       $parent.append(‘<span class=”formtips onSuccess”>’+okMsg+'</span>’);
                   }
                }
                if($(this).is(‘#email’)){
                    if(this.value==””||(this.value!=””&&!/.+@.+.[a-zA-Z]{2,4}$/.test(this.value))){
                        var errorMsg = ‘请输入正确的E-mail地址’;
                        $parent.append(‘<span class=”formtips onError”>’+errorMsg+'</span>’);
                    }else{
                        var okMsg = ‘输入正确’;
                        $parent.append(‘<span class=”formtips onSuccess”>’+okMsg+'</span>’);
                    }
                }
            });
            $(“form :input”).focus(function(){
                var $parent = $(this).parent();
