Question

我正在使用Leaflet绘制地图，在弹出窗口中我添加了一个链接，该链接应该导致更详细的描述，描述与地图分开并使用手风琴排列到列表中，因此每个描述都是隐藏的

我可以使用锚链接到手风琴内容，但我需要执行一些JavaScript onclick，所以我试图添加一个click事件处理程序 - 它不起作用。

这是我的代码：

您可以在JS Fiddle

上查看

我已经将这个作为github上的一个错误报告给了Leaflet here和here的开发者，但是他拒绝回复说这不是问题而我可以使用另一个class - 不起作用。

编辑：我自己也找到了一些：http://jsfiddle.net/M5Ntr/12/ 但是仍然存在一个问题，可能会有500分，所以我希望尽可能少的代码，我试图创建函数，但我不能传递变量：（

这是有效的

point["point_111_11"] = new L.Marker(new L.LatLng(51.4800166666667,-0.43673)).bindPopup("<b>Ioff</b> <br>**** ***").on('click', function (e) { console.log("clicked (Try to open Accordion): " + e.target) });

但这是优选的（不起作用）：

point["point_111_11"] = new L.Marker(new L.LatLng(51.4800166666667,-0.43673)).bindPopup("<b>Ioff</b> <br>**** ***").on('click', myfunction('point_111_11'));

function myfunction(seclectedId){
   //do something with seclectedId
   console.log(seclectedId)
}

甚至

point["point_111_11"] = new L.Marker(new L.LatLng(51.4800166666667,-0.43673)).bindPopup("<b>Ioff</b> <br>**** ***").myBindFunction('point_111_11')

将会执行.on（'click'）或类似内容......

Answer 1

如ticket you raised中所述，您可以创建DOM元素并将其传递给bindPopup方法......所以您可以这样做：

var domelem = document.createElement('a');
domelem.href = "#point_555_444";
domelem.innerHTML = "Click me";
domelem.onclick = function() {
    alert(this.href);
    // do whatever else you want to do - open accordion etc
};

point["point_555_44"] = new L.Marker(new L.LatLng(51.641485, -0.15362)).bindPopup(domelem);

您只需更新onclick功能即可执行您需要执行的操作....

无法绑定到Leaflet弹出窗口上的click事件
