Leaflet: Add a link to the markers

问题

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.

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);
}

This issue is really driving me nuts.

回答1:

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.

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;
}

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

You could also use a popup which can display HTML

marker.bindPopup(htmlString);

i found a similar code which may help you. here is jsfiddle link http://jsfiddle.net/farhatabbas/qeJ78/

 $(document).ready(function () {
        init_map();
        add_marker();
    });
    var map;

    function init_map() {
        map = L.map('map').setView([37.8, -96], 4);
        L.tileLayer('http://{s}.tile.cloudmade.com/{key}/22677/256/{z}/{x}/{y}.png', {
            attribution: 'Map data &copy; 2011 OpenStreetMap contributors, Imagery &copy; 2012 CloudMade',
            key: 'BC9A493B41014CAABB98F0471D759707'
        }).addTo(map);
    }

    function add_marker() {
        var points = [
            ["P1", 43.059908, -89.442229, "http://www.url_address_01.com/"],
            ["P2", 43.058618, -89.442032, "http://www.url_address_02.com/"],
            ["P3", 43.058618, -86.441726, "http://www.url_address_03.com/"]
        ];
        var marker = [];
        var i;
        for (i = 0; i < points.length; i++) {
            marker[i] = new L.Marker([points[i][1], points[i][2]], {
                win_url: points[i][3]
            });
            marker[i].addTo(map);
            marker[i].on('click', onClick);
        };
    }

    function onClick(e) {
        console.log(this.options.win_url);
        window.open(this.options.win_url);
    }
