Angular noob尝试使用Angular 1.2.21按照this geolocation示例逐步查看watchPosition。浏览器调试器显示服务位置对象在GPS触发时更新,但范围myCoords仍未定义。我尝试在几个地方添加$ apply,其中投掷正在进行中。这里有什么不对,我需要阅读哪些概念?
angular
.module('myApp', ['ngGeolocation'])
.controller('geolocCtrl', ['$geolocation', '$scope', function($geolocation, $scope) {
$geolocation.watchPosition({
timeout: 60000,
maximumAge: 250,
enableHighAccuracy: true
});
$scope.myCoords = $geolocation.position.coords; // not updated
$scope.myError = $geolocation.position.error; // this becomes truthy, and has 'code' and 'message' if an error occurs
}]);
答案 0 :(得分:2)
每次更新都会重新分配coords
的{{1}}属性。它是$geolocation.position
$ geolocation`保持不变。
所以,(基于你想如何使用它)你应该写这样的东西:
position object of
