Leaflet使用vector tiles 标注label设置

JS

    //简单的标注
        var marker = L.marker([ 31.2, 114.5 ], {
                    // icon:myIcon
                    }).addTo(map)
                    // 设置label
                    .bindTooltip("This is a test.", {
                        permanent : true,
                        offset : [ 0, 0 ],// 偏移
                        direction : "right",// 放置位置
                        // sticky:true,//是否标记在点上面
                        className : 'anim-tooltip',// CSS控制
                    }).openTooltip();

CSS

.anim-tooltip{
  transition: opacity 4.0s linear;/*动画效果*/
  font:italic bold 12px/30px arial,sans-serif;
  font-family:"Times New Roman",Georgia,Serif;
  /*字体发光*/
  text-shadow: 1px 0 0 #8B4513, 0 1px 0 #8B4513,
    0 -1px 0 #8B4513, -1px 0 0 #8B4513,
    1px 0 1px #8B4513, 0 1px 1px #8B4513,
    0 -1px 1px #8B4513, -1px 0 1px #8B4513;
