javascript - 如何判断所有可见图 block 何时已满载？

Question

是否有事件(或其他方法)来检测所有可见图 block 何时已下载并与传单一起显示？ (类似于 Google Maps event that is called when all visible map tiles are loaded ，但用于传单)

Answer 1

解决了。在瓦片图层上绑定(bind)“加载”事件。例子:

var tile_layer=L.tileLayer(tile_url,{
  attribution: "Map data &copy; <a href='http://openstreetmap.org'>OpenStreetMap</a> "+
    "contributors, <a href='http://creativecommons.org/licenses/by-sa/2.0/'>CC-BY-SA</a>.",
  maxZoom: 18
});
tile_layer.addTo(map);
tile_layer.on("load",function() { console.log("all visible tiles have been loaded") });
