iPhone5 未与 phonegap 建立数据连接

Question

我正在使用phonegap来检查是否有互联网连接

if(navigator.connection.type !== Connection.NONE){ ..do an ajax call

这在安卓中工作正常，但在 iPhone5 中，当 WiFi 关闭时，我只是得到connection = none，仅此而已......android至少进入3G并做这个电话。

我做错了什么？我是否必须强制iPhone5使用数据连接，如果是，如何？正如我所说，如果有WiFi连接，两者都可以正常工作。

尝试扫描所有连接

function checkConnection() {
var networkState = navigator.connection.type;
var states = {};
states[Connection.UNKNOWN]  = 'Unknown connection';
states[Connection.ETHERNET] = 'Ethernet connection';
states[Connection.WIFI]     = 'WiFi connection';
states[Connection.CELL_2G]  = 'Cell 2G connection';
states[Connection.CELL_3G]  = 'Cell 3G connection';
states[Connection.CELL_4G]  = 'Cell 4G connection';
states[Connection.NONE]     = 'No network connection';
if(states[networkState]=='No network connection'){
alert("no connection");
}
if(states[networkState]=='Cell 3G connection'){
//do something
}
...
...
}

对于检查所有连接，您可以尝试

if(states[networkState]=='No network connection'){
alert("no connection");
}else{
//do something
}
