我跟着this control-button-leaflet tutorial,它对我有用。现在我想:
以下是代码:
var customControl = L.Control.extend({
options: {
position: 'topleft'
},
onAdd: function (map) {
var container = L.DomUtil.create('div', 'leaflet-bar leaflet-control leaflet-control-custom');
container.style.backgroundColor = 'white';
container.style.backgroundImage = "url(http://t1.gstatic.com/images?q=tbn:ANd9GcR6FCUMW5bPn8C4PbKak2BJQQsmC-K9-mbYBeFZm1ZM2w2GRy40Ew)";
container.style.backgroundSize = "30px 30px";
container.style.width = '30px';
container.style.height = '30px';
container.onclick = function(){
console.log('buttonClicked');
}
return container;
}
});
var map;
var readyState = function(e){
map = new L.Map('map').setView([48.935, 18.14], 14);
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);
map.addControl(new customControl());
}
window.addEventListener('DOMContentLoaded', readyState);
答案 0 :(得分:11)
似乎你需要一个Button而不是div:
var container = L.DomUtil.create('input');
container.type="button";
然后您可以轻松设置鼠标悬停文字:
container.title="No cat";
一些文字而不是图片:
container.value = "42";
您可以使用鼠标事件设置按钮的样式:
container.onmouseover = function(){
container.style.backgroundColor = 'pink';
}
container.onmouseout = function(){
container.style.backgroundColor = 'white';
}
(你当然可以用css做最后一部分,可能更优雅)
