jVectorMaps中是否可以定义可以选择的静态区域?
我只需要定义允许用户选择的6个区域。
棘手的部分是,我需要将欧洲,亚洲和世界作为一个地区,并将“波兰”和“加拿大”作为一个地区。
如果用户选择波兰,则应仅选择“波兰”,但如果用户选择“欧洲”中的任何其他国家,则应选择所有欧洲国家。
jvectormaps有可能吗?
最佳答案
jVectorMap区域是由2个字母的ISO国家(地区)代码标识的SVG路径。
您可能没有合并这些路径,但是可以将国家代码收集到宏区域中,并使用这组代码一次选择所有需要的jVectorMap区域。
这是一个具有四个宏观区域的示例:波兰,加拿大,欧洲和世界其他地区。
$(document).ready(function () {
// Group states into Areas
var areas = [];
areas[0] = [];
areas[1] = ["PL"];
areas[2] = ["BE","FR","BG","DK","HR","DE","BA","HU","FI","BY","GR","NL","PT","NO","LV","LT","LU","XK","CH","EE","IS","AL","IT","CZ","GB","IE","ES","ME","MD","RO","RS","MK","SK","SI","UA","SE","AT"];
areas[3] = ["CA"];
function selectArea(code){
var mapObj = $("#map").vectorMap("get", "mapObject");
areas.forEach(function(area) {
if(area.indexOf(code)>-1) {
mapObj.setSelectedRegions(area);
return;
}
});
}
function clearAll(){
var mapObj = $("#map").vectorMap("get", "mapObject");
mapObj.clearSelectedRegions();
}
$("#map").vectorMap({
map: "world_mill",
backgroundColor: "aliceblue",
zoomOnScroll: true,
regionsSelectable: true,
regionStyle: {
initial: {
fill: "lightgrey"
},
selected: {
fill: "darkseagreen"
}
},
onRegionClick: function(e, code){
clearAll();
selectArea(code);
return false;
}
});
(function () {
// Collect the rest of the World
var mapObj = $("#map").vectorMap("get", "mapObject");
var states = areas.join(",");
for(var code in mapObj.regions) {
if(mapObj.regions.hasOwnProperty(code)) {
if(states.indexOf(code) == -1) {
areas[0].push(code);
}
}
}
})();
});
