Cordova phonegap中回调的含义是什么

使用position对象作为参数，将设备的当前位置返回到geolocationSuccess回调。如果有错误，geolocationError回调将传递一个PositionError对象

navigator.geolocation.getCurrentPosition(geolocationSuccess,
                                         [geolocationError],
                                         [geolocationOptions]);

geolocationSuccess是一个函数，您必须定义它，在一切正常的情况下触发它，如果出现错误则触发它

例如：

geolocationSuccess: function () {
  alert ("OK to get geolocation!")
}

geolocationError: function () {
  alert ("Something went wrong on geolocation")
}

navigator.geolocation.getCurrentPosition(geolocationSuccess,
                                         geolocationError,
                                         [geolocationOptions]);
