Question

我有一个iOS应用程序，它使用SimpleWeather插件收集实际天气信息（包括7天预报）。

现在......雅虎图像服务器已关闭（s.yimg.com），这会导致我的Flexslider脚本失效（无论出于何种原因）。我的头像这样：

    <head>

    <meta charset="utf-8" />
    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1" />

<script type="text/javascript">
        $(document).ready(function() {

                                    weatherForecastDay = 'Donnerstag';

                        $(".weatherBasicIcon").html('<img src="'+sBasicIcon+'" alt="" />');
                        $(".weatherBasicTemp").html(sBasicTemp);
                        $(".weatherBasicTempHead").html('<img width="45px" height="auto" src="'+sBasicIcon+'" alt="" /> '+sBasicTemp);
                        $(".weatherForecastAll").html(weatherForecastAll);
                },
                error: function(error) {
                    $(".weatherBasicTempHead").html('---');
                }
            });
        });
    </script>

我可以说哪个命令只能在互联网可用时执行天气脚本，最好是显示弹出窗口“没有互联网连接 - 天气不可用”。

谢谢！

Answer 1

您可以使用navigator.online：

if (navigator.onLine) {
    // I'm online so submit the form.
}

注意它适用于htmls 5和基于webkit的浏览器：）

Check if Internet Connection Exists with Javascript?

SimpleWeather.js - 仅在互联网可用时加载
