传单:向标记添加链接 [英] Leaflet: Add a link to the markers

问题描述

一个非常简单的问题:如何使Leaflet中的地图标记可单击，并将用户路由到其他页面?每个标记都有自己的页面.

Pretty simple question: How can I make the map markers in Leaflet clickable and route the user to an other page? Every marker has its own page.

我尝试了以下方法，但均未成功；所有标记都以某种方式指向同一页面，这是最后分配的URI.

I've tried the following without success; somehow all the markers point to the same page, which is the last assigned URI.

var markers = [
    { coords: [51.505, -0.09], uri: '/some-page' },
    ...
];

for(x in markers)
{
    L.marker(markers[x].coords).on('click', function() {
        window.location = markers[x].uri;
    }).addTo(map);
}

这个问题真的让我发疯.

This issue is really driving me nuts.

推荐答案

好的，我终于找到了解决方案.当将标记添加到地图时，将为其分配一个名为"_leaflet_id"的ID.可以通过目标对象获取此值，还可以在将其添加到地图后将其设置为自定义值 .

Okay, I finally came to a solution; when a marker is added to the map it gets assigned an ID called "_leaflet_id". This can be fetched through the target object, and also set to a custom value after it has been added to the map.

所以最终的解决方案很简单:

So the final solution is simply:

var x = markers.length;

while(x--)
{
    L.marker(markers[x].coords).on('click', function(e) {
        window.location = markers[e.target._leaflet_id].uri;
    }).addTo(map)._leaflet_id = x;
}

(我将for-in循环替换为反向的while循环)

(I replaced the for-in loop with a reversed while loop)
