【问题描述】:
我从 geoJson 中提取了一个要素图层,然后同步了一个表格。当我放大每个功能时,我试图做到这一点,它将表格过滤到这些功能。以下是我的脚本不起作用。我在 'if (map.getBounds().contains(layer.getBounds()))' 处收到错误,我可以寻求帮助吗?
var featureLayer = L.geoJson(null, {
filter: function(feature, layer) {
return feature.geometry.coordinates[0] !== 0 && feature.geometry.coordinates[1] !== 0;
},
pointToLayer: function (feature, latlng) {
return L.marker(latlng, {
title: feature.properties["status_title_github"],
riseOnHover: true,
icon: L.icon({
iconUrl: "assets/pictures/markers/cb0d0c.png",
iconSize: [30, 40],
iconAnchor: [15, 32]
})
});
},
onEachFeature: function (feature, layer) {
if (feature.properties) {
layer.on({
click: function (e) {
identifyFeature(L.stamp(layer));
highlightLayer.clearLayers();
highlightLayer.addData(featureLayer.getLayer(L.stamp(layer)).toGeoJSON());
},
mouseover: function (e) {
if (config.hoverProperty) {
$(".info-control").html(feature.properties[config.hoverProperty]);
$(".info-control").show();
}
},
mouseout: function (e) {
$(".info-control").hide();
}
});
if (feature.properties["marker-color"]) {
layer.setIcon(
L.icon({
iconUrl: "assets/pictures/markers/" + feature.properties["marker-color"].replace("#",'').toLowerCase() + ".png",
iconSize: [30, 40],
iconAnchor: [15, 32]
})
);
legendItems[feature.properties.Status] = feature.properties["marker-color"];
}
}
}
});
function syncTable() {
tableFeatures = [];
featureLayer.eachLayer(function (layer) {
layer.feature.properties.leaflet_stamp = L.stamp(layer);
if (map.hasLayer(featureLayer)) {
if (map.getBounds().contains(layer.getBounds())) {
tableFeatures.push(layer.feature.properties);
}
}
});
$("#table").bootstrapTable("load", JSON.parse(JSON.stringify(tableFeatures)));
var featureCount = $("#table").bootstrapTable("getData").length;
if (featureCount == 1) {
$("#feature-count").html($("#table").bootstrapTable("getData").length + " visible feature");
} else {
$("#feature-count").html($("#table").bootstrapTable("getData").length + " visible features");
}
}
