| “ | Connection對象提供對設備的蜂窩及WiFi連接信息的訪問。 |
通過navigator.network接口訪問該對象。
屬性：
- connection.type
常量：
- connection.UNKNOWN
- connection.ETHERNET
- connection.WIFI
- connection.CELL_2G
- connection.CELL_3G
- connection.CELL_4G
- connection.NONE
檢查正在使用的活動網絡連接。
說明：
該屬性是確定設備網絡連接狀態和連接類型的快速方法。
支持的平臺：
- iOS
- Android
- BlackBerry WebWorks (OS 5.0或更高版本)
簡單的範例：
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';
alert('Connection type: ' + states[networkState]);
}
