JS印证控件1.3

更新内容:

1.新增可以自定义提示参数名

2.提交等事件可以只绑定一次

3.整合一些常用的验证到里面去

            $$(validObjID(id)).innerHTML = '';
            return true;
        }
    }
}



调用方式

$(document).ready(function() {
            var vld = new Validator("btn_login", "click");
            vld.bind("txt_username", "用户名", [["empty", "*"]]);
            vld.bind("txt_password", "密码", [["empty", "*"]]);
            vld.valid();
            //绑定提交事件
            addEvent(document.getElementById("btn_login"), "click", function() {
            if (vld.IsValidator) {
                    login();
                }
            },'btn_login_onchick');
        })
