When I put my object (points) in the same script as the google maps API it works fine. But when I move the object to its own script on top it says "points is not defined".
I need to have the object in the top script (its actually coming from a database).
See working demo: https://price-points.web.app/
This is a Svelte project.
<script>
export const prerender = true;
let showMap = false;
//How can I make this work without the setTimeout?
setTimeout(function(){showMap = !showMap}, 1);
</script>
<!-- Google Maps API -->
<div>
<div id="map"></div>
<script>
//If points object is here it works fine.
//If points is defined in top script it says "points is not defined"
//My ACTUAL points object comes from a database and needs to be in top script.
let points = {
sanFrancisco: {
lat: 37.7749,
lng: -122.4194,
price: 123.45
},
losAngeles: {
lat: 34.0522,
lng: -118.2437,
price: 567.89
}
}
function initMap() {
const california = {lat: 36.7783,lng: -119.4179};
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 7,
center: california,
});
Object.values(points).forEach(({ lat, lng, price }) => {
const marker = new google.maps.Marker({
position: {lat: lat, lng: lng},
map: map,
label: `$${price}`,
icon: { url: 'https://i.imgur.com/ECXgKpB.png', scaledSize: new google.maps.Size(60,35), labelOrigin: new google.maps.Point(30, 15)}
});
});
}
window.initMap = initMap;
</script>
{#if showMap}
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap&v=weekly" defer async></script>
{/if}
</div>
<style>
#map {
height: 800px;
width: 100%;
}
</style>
The script in Svelte components is scoped (it is implicitly a module which requires import
/export
), you have to set window.points
to make variables available globally.
Note that in SvelteKit you cannot access window
during server-side rendering, so you probably should move the assignment into onMount
. In general you should not have multiple script tags in the first place, maybe you are fighting the wrong problem.
