我使用Mapbox.js设置了一个地图，我需要用外部按钮打开我的标记区域。我查看了mapbox.com的示例，发现“open popup programmatically”选项最适合。
然而，当我插入它时，它不能使用我的Json Script。我需要一些帮助吗？
我已经提供了我的[脚本]来查看下面的内容：
L.mapbox.accessToken = 'pk.eyJ1Ijoic21vcnJpczMiLCJhIjoiU1RtclNJMCJ9.AWDKQ9l9dY32tB5J8srivg';
var map = L.mapbox.map('mapbox', 'smorris3.78f0898a', {
attributionControl: false,
zoomControl: false,
legendControl: {
position: 'bottomleft'
}
})
.setView([32.888065, -96.964602], 11);
var myLayer = L.mapbox.featureLayer().addTo(map);
var geoJson = [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-96.964602, 32.888065]
},
"properties": {
"title": "My Title #1",
"description": "My Description #1",
"icon": {
"iconUrl": "http://www.clipartbest.com/cliparts/RTA/ArX/RTAArXyTL.png",
"iconSize": [30, 30], // size of the icon
"iconAnchor": [15, 15], // point of the icon which will correspond to marker's location
"popupAnchor": [0, -15], // point from which the popup should open relative to the iconAnchor
"className": "dot"
}
}
}, {
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-111.858841, 33.436066]
},
"properties": {

}
}
}

解决。这部分：
map.featureLayer.on('ready', function(e) {
document.getElementById('open-popup').onclick = clickButton;
});
永远不会开火，因为你已经有另一个事件：
myLayer.on('layeradd', function(e) {
onready事件用于异步调用。 Reference here
L.mapbox.accessToken = 'pk.eyJ1Ijoic21vcnJpczMiLCJhIjoiU1RtclNJMCJ9.AWDKQ9l9dY32tB5J8srivg';
