如何在地图上show/hide?
How to show/hide on geo map?
到目前为止,我终于创建了一个地理地图,其中包含节点和连接它们的线。所有节点都有持有者 ID 和母公司。但是我想要一个功能,您可以在其中双击节点,它只会显示所选节点及其连接的节点。我不知道该怎么做,因为我不知道如何将我创建的线连接到节点。我在 JSFiddle 上重新创建了示例:http://jsfiddle.net/GarrettUK/x9058g8s/2/。如有任何问题,请随时提出,在此先感谢您!
holderID是公司,parentCompany是拥有所选节点的节点:
name: 'Tesco',
radius: 6,
fillKey: 'Negative',
holderID: 2,
parentCompany: 1,
balance: '2393',
date: '11/07/2005',
latitude: 48.632909,
longitude: 35.024414
您可以 select nodes
和 links
宽度 D3.js:
var bnodes = d3.selectAll('.datamaps-bubble');
var blinks = d3.selectAll('.datamaps-arc');
然后您可以计算额外的信息以在双击时更有效地执行 select 节点和链接的离子,例如:
blinks.each(function(dl, il) {
bnodes.each(function(d,i) {
if (dl.origin.latitude == d.latitude) {
dl.origin.holderID = d.holderID;
} else if (dl.destination.longitude == d.longitude) {
dl.destination.holderID = d.holderID;
}
})
});
然后双击 event
仅显示链接的节点和链接:
bnodes.on('dblclick', function(d, i) {
blinks.classed('hide', true);
bnodes.classed('hide', true);
connectedNodes = [d.holderID];
blinks.filter(function(dl,il) {
if (dl.origin.holderID == d.holderID) {
connectedNodes.push(dl.destination.holderID);
return true;
} else if (dl.destination.holderID == d.holderID) {
connectedNodes.push(dl.origin.holderID);
return true;
}
return false;
}).classed('hide', false);
bnodes.filter(function(dd,ii) {
return connectedNodes.indexOf(dd.holderID) > -1;
}).classed('hide', false);
});
最后是 Fiddle:http://jsfiddle.net/x9058g8s/5/ 和片段:
