这是我的geojson数据
var json = '[{"type": "FeatureCollection", "crs": {"properties": {"type": "proj4", "href": "http://spatialreference.org/ref/epsg/4326/"}, "type": "link"}, "features": [{"properties": {"species": "Oxalis corniculata L.", "listvalues": 0, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 1}, {"properties": {"species": "Pinus roxburghii Sargen", "listvalues": 2, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 2}, {"properties": {"species": "Trifolium repens L.", "listvalues": 1, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 3}, {"properties": {"species": "Poa annua L.", "listvalues": 0, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 4}, {"properties": {"species": "Fragaria nubicola Lindley ex Lacatia", "listvalues": 0, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 5}, {"properties": {"species": "Cedrus deodara (Roxb. ex Lambert.) G.Don.", "listvalues": 2, "model": "pft.existing_data_apft"}, "type": "Feature", "geometry": {"coordinates": [76.320083, 32.233167], "type": "Point"}, "id": 6}]}]'
我想要以下结果：
(1) All species whose listvalues=0
(2) All species whose listvalues=1
(3) All species whose listvalues=2
如何使用jquery或javascript实现此目的？
javascript代码
<script type="text/javascript">
$('.bottom').hide(); // initially hide the bottom content
//set event listener to trigger on header click
$('.header').click(function() {
$(this).next('.bottom').slideToggle();// find the next bottom content afterthe header and toggle it up or down depending on its current state.
});
function main_map_init (map, options) {
var promise = $.getJSON('{% url "extdata" %}');
promise.then(function(data) {
var allbusinesses = L.geoJson(data);
var cafes = L.geoJson(data, {
pointToLayer: function(feature, latlng) {
return new L.CircleMarker(latlng, {
