我在 YouTube 上关注了本教程:https://www.youtube.com/watch?v=gw3AKC4MsGQ
我做了所有相同的事情，但遇到了一个小问题，因为自视频制作以来 JavaScript 已更新。关于应该对我的代码进行哪些更改以适应 JavaScript 中的更改的任何想法？
这是 HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
<title></title>
<link rel="manifest" href="manifest.json">
<!-- un-comment this code to enable service worker
<script>
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('service-worker.js')
.then(() => console.log('service worker installed'))
.catch(err => console.log('Error', err));
}
</script>-->
<link href="lib/ionic/css/ionic.css" rel="stylesheet">
<link href="css/style.css" rel="stylesheet">
<!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
<link href="css/ionic.app.css" rel="stylesheet">
-->
<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>
<!-- cordova script (this will be a 404 during development) -->
<script src="cordova.js"></script>
<!-- your app's js -->
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCMsQzZKDhyiXUMOxllFxi5iBz1tZ1j-mc&callback=initMap">
</script>
<script type="js/direction.js"></script>
<script src="js/app.js"></script>
</head>
<body ng-app="starter">
<ion-pane>
<ion-header-bar class="bar-positive">
<h1 class="title">Get Directions</h1>
</ion-header-bar>
<ion-content>
<div id="map"></div>
</ion-content>
</ion-pane>
这是 JavaScript:
function initMap() {
var directionsService = new google.maps.DirectionsService();
var directionsDisplay = new google.maps.DirectionsRenderer();
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 7,
center: {lat: 41.85, lng: -87.65}
});
directionsDisplay.setMap(map);
var onChangeHandler = function() {
calculateAndDisplayRoute(directionsService, directionsDisplay);
};
document.getElementById('start').addEventListener('change', onChangeHandler);
document.getElementById('end').addEventListener('change', onChangeHandler);
}
function calculateAndDisplayRoute(directionsService, directionsDisplay) {
directionsService.route({
origin: document.getElementById('start').value,
destination: document.getElementById('end').value,
travelMode: 'DRIVING'
}, function(response, status) {
if (status === 'OK') {
directionsDisplay.setDirections(response);
} else {
window.alert('Directions request failed due to ' + status);
}
});
}
最佳答案
type="js/direction.js"，它将是 src="js/direction.js"
