android - 如何使用 phonegap (1.8.0) 检测网络 isReachable

Question

我正在使用 phonegap1.8.0，我想检测网络是否可用，然后我是否可以连接到它。在电话间隙 doc公开以下 api

navigator.network.isReachable('www.facebook.com', reachCallBack, {});

但是，我得到了

Console(4820): Uncaught TypeError: Object #<Object> has no method 'isReachable' at file:///android_asset/www/index.html:71

代码是:

    function netIsAvailable()
{
    var reachCallBack = function (reachability)
    {

        var networkState = reachability.code || reachability;

        var states = {};
        states[NetworkStatus.NOT_REACHABLE]                      = 'No network connection';
        states[NetworkStatus.REACHABLE_VIA_CARRIER_DATA_NETWORK] = 'Carrier data connection';
        states[NetworkStatus.REACHABLE_VIA_WIFI_NETWORK]         = 'WiFi connection';

        alert('Connection type: ' + states[networkState]);

    };
    alert(  navigator.onLine );
    navigator.network.isReachable('www.facebook.com', reachCallBack, {});
}

Answer 1

isReachable 函数自 v1 以来已弃用，现在您必须使用 connection 或网络事件来执行类似的逻辑。

Connection information

online/offline events
