关于cordova检测网络 connection的问题 求各位大神解答

璐璐璐璐璐

var states = {};后面的带完不运行，alert（）不出，改成states[navigator.connection.UNKNOWN]  = 'Unknown connection';states[navigator.connection.ETHERNET] = 'Ethernet connection';
states[navigator.connection.WIFI]     = 'WiFi connection';
states[navigator.connection.CELL_2G]  = 'Cell 2G connection';
states[navigator.connection.CELL_3G]  = 'Cell 3G connection';
states[navigator.connection.CELL_4G]  = 'Cell 4G connection';
states[navigator.connection.CELL]     = 'Cell generic connection';
states[navigator.connection.NONE]     = 'No network connection';之后永远都会显示Unknown connection 怎么回事 坐等各位大神解答

你懂的

正常应该可以，你手机运行的吗，看看官方文档是不是变了
