Leaflet map not showing despite following quick-start guide-CodePudding

The problem I am having is that the map is not showing up at all, there is a blank spot where the map is meant to be. I have followed Leaflet's quick-start guide and I still have yet to determine why my map does not show.

Below is the code I have so far:

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Title</title>

            var mymap = L.map('mapid').setView([51.505, -0.09], 13);

            L.tileLayer('https://api.mapbox.com/styles/v1/{id}/tiles/{z}/{x}/{y}?access_token={accessToken}', {

            }).addTo(mymap);
        </script>
    </body>
</html>

CodePudding user response：

You import the Leaflet JavaScript file and have your page code within the same HTML <script> tag. In such case, browsers are supposed to ignore (not execute) the content between the script tags, i.e. your page code is not executed.

Simply separate in 2 different script tag pairs:

<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>
<script>
var mymap = L.map('mapid').setView([51.505, -0.09], 13);
// etc.
</script>
