Question

我有一个特定的要求，我必须使用dojo 1.9进行简单的地理地图。我从openlayer站点下载了openlayer.js，但是当我运行页面时，没有显示任何内容。如果有人能帮助我完成我的遗失，我将不胜感激。请找到以下代码。

<html>
<head>
<link rel="stylesheet" type="text/css" href="../../dijit/themes/dijit.css">
<link rel="stylesheet" type="text/css" href="../../dijit/themes/tundra/tundra.css">
<link rel="stylesheet" type="text/css" href="demo.css">
<title>Map</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript" src="../../dijit/themes/tundra/OpenLayers.js"></script>
<script type="text/javascript" src="../../dojo/dojo.js" data-dojo-config="async: true"></script>
<script type="text/javascript" src="src.js"></script>
</head>
</html>

Dojo容器中的OpenLayers映射：

<!DOCTYPE html>

            <div data-dojo-type='dijit/layout/ContentPane' data-dojo-props='region:"trailing"'>
                Just an example
            </div>
        </div>
        <script type='text/javascript'>
        require(['dojo/ready', 'dojo/parser'], function (ready, Parser) {
            ready(function () {
                Parser.parse().then(function () {
                    var map = new OpenLayers.Map({
                        div:'map',
                        displayProjection:new OpenLayers.Projection('EPSG:4326'),
                        projection:new OpenLayers.Projection('EPSG:900913')
                    });
                    map.addLayer(
                        new OpenLayers.Layer.OSM()
                    );
                    map.setCenter(
                        new OpenLayers.LonLat(0, 0),
                        2
                    );
                });
            });
        });
        </script>
    </body>
</html>

100％的宽度和高度会扩展所有内容以填充视口。虽然您不需要扩展到100％，但您需要在这些元素上设置尺寸。
