問題描述

我遵循了 這個 control-button-leaflet 教程，它對我有用.現在我想:

1. 當我將鼠標懸停在按鈕上時顯示一些文本(例如使用縮放按鈕)
2. 當我將鼠標懸停在按鈕上時更改按鈕的顏色
3. 能夠在按鈕內寫入文本而不是圖像.

代碼如下:

 var customControl = L.Control.extend({選項: {位置:左上角"},onAdd:函數(地圖){var container = L.DomUtil.create('div', 'leaflet-bar Leaflet-control Leaflet-control-custom');container.style.backgroundColor = '白色';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 = 函數(){console.log('buttonClicked');}返回容器；}});變量映射；var readyState = 函數(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);

看來你比 div 更需要 Button:

 var container = L.DomUtil.create('input');容器.type="按鈕";

1. 然后就可以輕松設置鼠標懸停文本了:

   container.title="沒有貓";

2. 還有一些文字而不是圖片:

   container.value = "42";

3. 您可以使用鼠標事件來設置按鈕樣式:

   container.onmouseover = function(){container.style.backgroundColor = '粉色';}容器.onmouseout = 函數(){container.style.backgroundColor = '白色';}

(你當然可以用 css 完成最后一部分，可能更優雅)

I followed this control-button-leaflet tutorial and it worked for me. Now I want to:

1. show some text when i hover over the button (like with the zoom buttons)
2. Change the color of the button when i hover over it
3. be able to write text inside the button instead of an image.

Here's the code:

    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);

It seems you more need a Button than a div:

    var container = L.DomUtil.create('input');
    container.type="button";

1. Then you can easily set a mouseover text:

   container.title="No cat";
   

2. And some Text instead of an image:

   container.value = "42";
   

3. And you can use the mouse events to style the button:

   container.onmouseover = function(){
     container.style.backgroundColor = 'pink'; 
   }
   container.onmouseout = function(){
     container.style.backgroundColor = 'white'; 
   }
   

(you could of course do this last part with css, might be more elegant)
