Question

我在我的一个项目中加入了传单。我的问题是图标没有显示在工具栏中。它看起来像这样：

环顾四周，我找到了THIS帖子并按照说明做了。我将spritesheet放在Leaflet Draw文件夹中，并像htis一样链接到它：

    .leaflet-draw-toolbar a {
            background-image: url('E:/MappingProject/Leaflet.Draw/src/images/spritesheet.png');
            background-repeat: no-repeat;
        }

我最终得到了这个：

我似乎无法找到任何其他解决方案来让这个spritesheet排成一行。看起来不是拉动单个图标，而是将整个工作表放在每个按钮中。

这是我实例化L.FeatureGroup（）和L.Control.Draw（）的代码：

    function logIn(){
        map = L.map('map').setView([51.505, -0.09], 13);
        OpenStreetMap_HOT.addTo(map);
        $("#logInScreen").css('display', 'none');
        addSideBars();
        addDrawToMap();
    }        

/////////////////////////////////////////////
        //DRAW FUNCTIONALITY

        function addDrawToMap(){
            map.addControl(drawControl);
            map.addLayer(drawnItems);
        }
        var drawnItems = new L.FeatureGroup();
            var drawControl = new L.Control.Draw({
                position: 'topright',
                draw: {
                    polyline: true,
                    polygon: true,
                    circle: true,
                    marker: true
                },
                edit: {
                    featureGroup: drawnItems,
                    remove: true
                }
            });

任何人都有这方面的经验吗？

很可能你错过了Leaflet-draw CSS file。

在该文件中定义了.leaflet-draw-toolbar a之类的CSS规则。

没有此文件的示例，但使用了CSS规则：

＆＃13;

var map = L.map('map').setView([48.86, 2.35], 11);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

var drawControl = new L.Control.Draw({
  position: 'topright'
});
map.addControl(drawControl);

＆＃13;

.leaflet-draw-toolbar a {
  background-image: url('https://unpkg.com/leaflet-draw@1.0.2/dist/images/spritesheet.png');
  background-repeat: no-repeat;
  color: transparent !important;
}

＆＃13;

此文件的示例：

var map = L.map('map').setView([48.86, 2.35], 11);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {

var drawControl = new L.Control.Draw({
  position: 'topright'
});
map.addControl(drawControl);
