Connection对象提供对设备的蜂窝及WiFi连接信息的访问。 通过navigator.network接口访问该对象。
属性:
常量:
connection.type
检查正在使用的活动网络连接。
说明: 该属性是确定设备网络连接状态和连接类型的快速方法。
支持的平台:
- iOS
- Android
- BlackBerry WebWorks (OS 5.0或更高版本)
简单的范例:
- <span style="font-size:13px;">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]);
- }
-
- checkConnection();</span>
复制代码
完整的范例:
- <!DOCTYPE html>
- <html>
- <head>
- <title>navigator.network.connection.type Example</title>
-
- <script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
- <script type="text/javascript" charset="utf-8">
-
- // 等待加载PhoneGap
- document.addEventListener(“deviceready“, onDeviceReady, false);
-
- // PhoneGap加载完毕,可以安全调用PhoneGap方法
- function onDeviceReady() {
- checkConnection();
- }
-
- 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]);
- }
-
- </script>
- </head>
- <body>
- <p>A dialog box will report the network state.</p>
- </body>
- </html>
