您好我使用d3 js和数据地图,我想展示世界上少数几个国家/地区。我已经在在线论坛上查看了帮助,但没有得到明确的想法或回复。
源代码:
<div id="container" style="position: relative; width: 900px; height: 500px;"></div>
<script src="http://cdnjs.cloudflare.com/ajax/libs/d3/3.5.3/d3.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/topojson/1.6.9/topojson.min.js"></script>
<script src="http://datamaps.github.io/scripts/0.4.4/datamaps.world.min.js"></script>
<script>
var map = new Datamap({
element: document.getElementById('container'),
fills: {
HIGH: '#afafaf',
LOW: '#123456',
MEDIUM: 'blue',
UNKNOWN: 'rgb(0,0,0)',
defaultFill: 'green'
},
dataType: 'json', //for use with dataUrl, currently 'json' or 'csv'. CSV should have an `id` column
dataUrl: null,
geographyConfig: {
dataUrl: null, //if not null, datamaps will fetch the map JSON (currently only supports topojson)
hideAntarctica: true,
borderWidth: 1,
borderOpacity: 1,
borderColor: '#FDFDFD',
popupTemplate: function(geography, data) { //this function should just return a string
return '<div class="hoverinfo"><strong>' + geography.properties.name + '</strong></div>';
},
popupOnHover: true, //disable the popup while hovering
highlightOnHover: true,
highlightFillColor: '#FC8D59',
highlightBorderColor: 'rgba(250, 15, 160, 0.2)',
highlightBorderWidth: 2,
highlightBorderOpacity: 1
},
done: function(datamap) {
datamap.svg.selectAll('.datamaps-subunit').on('click', function(geography) {
console.log(geography);
var url = window.location.href;
var arr = url.split("/");
var result = arr[0] + "//" + arr[2]
window.open(result+'/countries/view/'+geography.properties.name);
});
}
});
</script>
它会显示所有国家/地区。但我想展示几个国家。 我如何通过那里的国家名单? 我想在custom.json或topojson的帮助下。我不知道。如果您有任何解决方案或指导,请告诉我。
