Dưới đây là một liên kết dropbox đến GEOJSONS nếu có ai muốn nhìn thấy họ (hy vọng công trình này như dự định và người có thể tải xuống chúng): https://www.dropbox.com/sh/4bi70dx2t99qgln/AABJfyNDJzgNTQK4Wu3vYnVRa?dl=0
Tôi đã làm việc trên một dự án để tạo một sơ đồ trong Leaflet sử dụng GEOJSON polylines. Tôi chỉ mới làm quen với JavaScript và Leaflet. Dưới đây là một ví dụ về những gì tôi muốn thực hiện (bản đồ của tôi sử dụng dòng rhumb và sẽ là tương tác):
Đây là cập nhật và chức năng rằng những thay đổi trọng lượng polyline dựa trên 'Giá trị' của mình làm việc từ tập tin GeoJSON (tín dụng để Hinrich & Jonathan sự giúp đỡ của họ!):
function getStyle1(feature){
var weight;
if (feature.properties.Value > 30000000) {weight = 20;}
else if (feature.properties.Value > 10000000) {weight = 18;}
else if (feature.properties.Value > 5000000) {weight = 16;}
else if (feature.properties.Value > 1000000) {weight = 14;}
else if (feature.properties.Value > 500000) {weight = 12;}
else if (feature.properties.Value > 100000) {weight = 10;}
else if (feature.properties.Value > 1000) {weight = 8;}
else if (feature.properties.Value > 1) {weight = 6;};
return {
color: 'red',
weight: weight
}
};
var CHNimports = L.geoJson(CHN, {
style: getStyle1,
onEachFeature: function (feature, layer) {
layer.bindPopup("<b>"+"Import Partner: "+feature.properties.Partner+"</b>"+ "<br />Dollar value of imports to China: " + feature.properties.Value);
},
pointToLayer: function (feature, latlng) {
return L.polyline(latlng);
}
}).addTo(map);
các dòng khác nhau tùy theo giá trị và tôi sẽ có thể thay đổi màu sắc phụ thuộc vào nước nhưng thông tin cửa sổ bật lên không xuất hiện khi một polyline được nhấp vào.
Bên cạnh đó, đây là một mẫu của tập tin GeoJSON cho CHNimports:
var CHN = {"type":"FeatureCollection","features":[{"type":"Feature","properties":{"Partner":"Algeria","LongX":1.659626,"LatY":28.033886,"CHNLong":104.195397,"CHNLat":35.86166,"Value":587},"geometry":{"type":"LineString","coordinates":[[1.659626,28.033886],[1.669754918002165,28.034691811007274],[1.679883911463014,28.035497621919983],[1.690012980385739,28.036303432738126],[1.700142124773322,28.037109243461707],[1.710271344628953,28.03791505409072],[1.720400639955684,28.038720864625162],[1.730530010756992,28.039526675065034],[1.74065945703536,28.040332485410335],[1.750788978794404,28.041138295661067],[1.760918576037107,28.041944105817212],[1.771048248766518,28.042749915878783],[1.781177996986042,28.04355572584578],[1.791307820698163,28.044361535718185],[1.801437719906642,28.045167345496015],[1.811567694614244,28.045973155179254],[1.821697744824234,28.04677896476791],[1.831827870539733,28.04758477426198],[1.841958071763792,28.04839058366145],[1.852088348499675,28.04919639296634],[1.862218700750077,28.050002202176625], ...continued on

Chào mừng bạn đến với stackoverflow! Nếu bạn yêu cầu người khác đọc và hiểu mã của bạn, định dạng mã thích hợp chắc chắn sẽ hữu ích. Nếu bạn có thể quản lý để giảm câu hỏi của bạn thành một vấn đề cụ thể, bạn dường như không thể giải quyết, độc lập với đầu vào cụ thể của bạn, điều này cũng sẽ giúp thu hút nhiều người hơn xem câu hỏi của bạn. – ralfstx
@ralfstx, Hy vọng rằng bản chỉnh sửa của tôi phù hợp hơn với những gì bạn muốn nói. Cảm ơn bạn đã trả lời nhanh chóng. – shadowninja1012
Nếu bạn đã đăng toàn bộ tập lệnh sẽ giúp ích rất nhiều!Có thể thấy cách bạn gọi getWeight(), những gì bạn đang mong đợi đã quay trở lại và cách bạn truy cập vào tệp GeoJSON tất cả sẽ giúp ích gì! –
