嗯,我想结合2个例子来从我的geojson文件搜索,并选择它时,将放大该属性。传单geojson搜索和缩放
搜索(在GeoJSON的一个搜索)http://labs.easyblog.it/maps/leaflet-search/examples/
放大部分从这里(没有下拉)http://projects.bryanmcbride.com/leaflet/select_zoom.html
基本上第一个刚刚从第二变焦。我已经能够让他们工作,但分开。
代码(1)
var featuresLayer = new L.GeoJSON(piirid, {
style: function(f) {
return {color: f.properties.color };
}
});
map.addLayer(featuresLayer);
var searchControl = new L.Control.Search({layer: featuresLayer, propertyName: 'L_AADRESS', circleLocation:false});
searchControl.on('search_locationfound', function(e) {
e.layer.setStyle({fillColor: '#3f0', color: '#0f0'});
}).on('search_collapsed', function(e) {
featuresLayer.eachLayer(function(layer) { //restore feature color
featuresLayer.resetStyle(layer);
});
});
map.addControl(searchControl); //inizialize search control
代码2
// Loop through the geojson features and extract bbox and name, then add the options to the "zoom" select (no jQuery)
/*var select = document.getElementById("zoom");
select.options[select.options.length] = new Option('Select a State', 'Select a State');
for (each in geojson._layers) {
var bbox = geojson._layers[each].getBounds()._southWest.lat + "," + geojson._layers[each].getBounds()._southWest.lng + "," + geojson._layers[each].getBounds()._northEast.lat + "," + geojson._layers[each].getBounds()._northEast.lng;
select.options[select.options.length] = new Option(geojson._layers[each].feature.properties.name, bbox);
}*/
// Loop through the geojson features and extract bbox and name, then add the options to the "zoom" select and build autocomplete(using jquery)
var options = '<option value="Select a State">Select a State</option>';
var states = [];
for (each in geojson._layers) {
var L_AADRESS = geojson._layers[each].feature.properties.L_AADRESS;
var swLat = geojson._layers[each].getBounds()._southWest.lat;
var swLng = geojson._layers[each].getBounds()._southWest.lng;
var neLat = geojson._layers[each].getBounds()._northEast.lat;
var neLng = geojson._layers[each].getBounds()._northEast.lng;
var bbox = swLat + "," + swLng + "," + neLat + "," + neLng;
// Populate states array and build autocomplete
states.push({label: L_AADRESS, value: L_AADRESS, swlat: swLat, swlng: swLng, nelat: neLat, nelng: neLng});
$("#search").autocomplete({
source: states,
minLength: 3,
select: function(event, ui) {
map.fitBounds([[ui.item.swlat, ui.item.swlng],[ui.item.nelat, ui.item.nelng]]);
}
});
// Add states & bbox values to zoom select options
options += '<option value="' + bbox + '">' + geojson._layers[each].feature.properties.L_AADRESS + '</option>';
}
