我看到几个不同的选项来检查与phonegap的互联网连接.有document.addEventListener(“online”,onOnline,false);还有navigator.network.connection.type ……但我不确定哪一个是最佳实践.我还希望能够防止手机连接到wifi网络但没有互联网连接的坏情况.
- $(document).on('pagecreate','#explanation-short',function(){
- if ( isPhoneGap() ) {
- if (checkConnection() == "none" ) {
- connectionStatus = 'offline';
- } else {
- connectionStatus = 'online';
- }
- function checkConnection() {
- var networkState = navigator.network.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';
- //console.log('Connection : ' + Connection);
- //console.log('Connection type: ' + states[networkState]);
- return networkState;
- }
- } else {
- connectionStatus = navigator.onLine ? 'online' : 'offline';
- }
- console.log("connectionStatus : "+connectionStatus);
- });
例如,如果手机连接到wifi,此代码有效,但我们不确定互联网是否实际可用.
phonegap 3.3和Jquery mobile 1.4的最佳实践是什么？
解决方法
事件,
- document.addEventListener("online",false);
仅在您的应用已加载并重新获得连接时才会触发.在应用程序启动时不会触发此操作.
因此,您必须在启动应用程序时使用checkConnection()方法,然后如果您需要在应用程序运行时稍后检查,则使用事件侦听器.
