方法一：在MainActivity中检查然后传递参数到html

public class MainActivity extends DroidGap  {

	@Override
    public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo info = cm.getActiveNetworkInfo();
         if (info != null){
        	 if (info.isAvailable()){
        		 super.loadUrl("http://www.baidu.com",6000);
        	 }else{
            	 super.loadUrl(Config.getStartUrl());
             }
         }else{
        	 super.loadUrl(Config.getStartUrl());
         }
    }

}

方法二：直接在html中检测

function checkConnection() {
            var networkState = navigator.network.connection.type;
            var states = {};
            states[Connection.UNKNOWN]  = 1;
            states[Connection.ETHERNET] = 2;
            states[Connection.WIFI]     = 3;
            states[Connection.CELL_2G]  = 4;
            states[Connection.CELL_3G]  = 5;
            states[Connection.CELL_4G]  = 6;
            states[Connection.NONE]     = 0;

            alert('Connection type: ' + states[networkState]);
        }
