javascript – event.keyCode无法在Firefox中运行

我正在使用ASP.net C#开发的登录页面出现问题.
该表单适用于IE,但不适用于Firefox.
这是我的样本：

            </div>
        </form>
    </body>
</html>

我注意到这部分……

function ValidarEnter(src)
            {
                if (event.keyCode == "13")
                {
                    actLogin();
                }
            }

当我在firefox上调试它时,它只是跳过它.
我已经尝试添加window.event.keyCode …并且还只用13开关“13”…
我怎么能在这周围工作？

解决方法

Firefox不支持event.keycode.使用event.which for firefox.

function checkKey(evt) {
  var keyID = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
  alert(keyID);
}

javascript – event.keyCode无法在Firefox中运行

解决方法

猜你在找的JavaScript相关文章
