来自 URL 的 Mapbox JS,GeoJSON featureCollection 对象仅添加一个标记
Mapbox JS, GeoJSON featureCollection object from URL only adds one marker
这张地图 http://lastablaslift.es/explorador/ 正在通过 csv2geojson 插件加载本地 CSV 文件,以向其中添加一些带有弹出窗口的标记。
我们正在尝试将 URL 端点放在一起,以从 mysql 数据库而不是 CSV 获取 geoJSON。
这张地图,http://lastablaslift.es/explorador/map_test.php,是一样的,但使用了我们 URL 的 geoJSON。
似乎我们已经得到 URL 返回格式正确的 GeoJSON,但如您所见,只有 "features" 数组中的第一个对象被呈现在 map_test.php
我正在将两个 geoJSON 对象记录到控制台,当我比较它们时,它们对我来说看起来是一样的。也没有报告相关错误,那么我们 URL 的 geoJSON 有什么问题?
看到这个 JSFiddle example.I 认为会有与 function change() {}
相关的问题,你放在 $.getJSON 成功函数中。试着把它放在外面。
你的map_jsonurl.js应该是这样的,
(function() {
var image = new Image();
image.onload = function() {
if (image.width > 0) {
document.documentElement.className += (document.documentElement.className != '') ? ' images-on' : 'images-on';
}
};
image.src = '/img/px.png';
}());
//toggle the filter menu
/*$("#f_tog").on("click", function(){
$("#filters").slideToggle();
$("#f_tog span").toggle();
});*/
// load the map data
$.getJSON("//civicliftmapeurope.azurewebsites.net/api/Listing", function(data) {
//initialize the map
var map = L.mapbox.map('map', 'ptw111.lgof8gop')
.setView([40.5023056, -3.6704803], 14);
//center marker on click
map.markerLayer.on('click', function(e) {
map.panTo(e.layer.getLatLng());
});
// Add custom popups to each using our custom feature properties
map.featureLayer.on('layeradd', function(e) {
var marker = e.layer,
feature = marker.feature;
//string functions, cleaning up geoJSON for display.
//clean up address
var addr;
var zip = feature.properties.zip;
if (feature.properties.addr) {
addr = feature.properties.addr + ', ' + zip + '<br>' + feature.properties.city + ', España';
}
//check for description
var desc;
if (feature.properties.description) {
desc = feature.properties.description;
} else {
desc = '';
}
//check for phone numbers
var phone;
if (feature.properties.phone) {
phone = '<strong>' + feature.properties.phone + '</strong>';
} else {
phone = '';
}
// create custom popup content
var popupContent = '<div class="tooltip"><h2>' + feature.properties.name + '</h2>' +
phone +
'<div class="addr"><p>' +
addr +
'</p></div><span>' +
desc +
'</span></div>';
// http://leafletjs.com/reference.html#popup
marker.bindPopup(popupContent, {
closeButton: false,
minWidth: 150,
});
});
// Add features to the map
map.featureLayer.setGeoJSON(data);
//filter locations by color/type
var filters = document.getElementById('filters');
var checkboxes = document.getElementsByClassName('filter');
// When the form is touched, re-filter markers
filters.onchange = change;
// Initially filter the markers
change();
});
function change() {
// Find all checkboxes that are checked and build a list of their values
var on = [];
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].checked) on.push(checkboxes[i].value);
}
// The filter function takes a GeoJSON feature object
// and returns true to show it or false to hide it.
map.markerLayer.setFilter(function(f) {
// check each marker's color to see if its value is in the list
// of colors that should be on, stored in the 'on' array
return on.indexOf(f.properties['marker-color']) !== -1;
});
return false;
