问题:

I tried out Leafletjs maxBounds with example code I found at Mapbox.

Below you find my complete code, also in a jsfiddle here.

<!DOCTYPE HTML>
<html>
<head>
    <title>map - leaflet test bounds</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1, minimal-ui" />
        <meta http-equiv="X-UA-Compatible" content="IE=edge">

        <!-- leafletjs -->
        <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css" />
        <script src="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js"></script>

        <style>
            body {
                margin: 0;
                padding: 0;
            }
            html, body, #map {
                height: 100%;
                width: 100%;
            }
        </style>
</head>

<body>
    <div id="map">
        <script>

            var southWest = L.latLng(40.712, -74.227),
                northEast = L.latLng(40.774, -74.125),
                mybounds = L.latLngBounds(southWest, northEast);

            var map = L.map('map').setView([40.743, -74.176], 17);
            L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png' , {
                maxBounds: mybounds,
                maxZoom: 18,
                minZoom: 16,
                attribution: '&copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'
            }) .addTo(map);

            L.marker([40.743, -74.176]) .addTo(map);

        </script>
    </div>        
</body>

The jsfiddle result looks odd, I don't know why.

Why doesn't the upper code work like the Mapbox example?

回答1:

You must use bounds as an option of L.tileLayer, and not maxBounds.

Bounds reference

Also, it seems you've loaded a wrong file for the leaflet.css in JSFiddle, the correct source is this: http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css

Finally, avoid to use percent sizes in JSFiddle, use pixel ones instead. Here's a working JSFiddle: http://jsfiddle.net/1zyL4q4a/4/

 L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png' , {
            bounds: mybounds,
            maxZoom: 18,
            minZoom: 16,
            attribution: '&copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'
  }).addTo(map);

回答2:

This is the (my) final code.

var map = L.map('map', {
    maxZoom: 18,
    minZoom: 16,
    maxBounds: [
        //south west
        [40.712, -74.227],
        //north east
        [40.774, -74.125]
        ], 
}).setView([40.743, -74.176], 17);

L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'
}) .addTo(map);

L.marker([40.743, -74.176]) .addTo(map);
