我正在使用jVectorMap插件向网站添加地图。这是我在页面加载时添加标记的地图。有没有办法动态地做到这一点?我需要在鼠标点击时添加它们。我使用jVectorMap插件
var plants = [
{name: 'VAK', coords: [-25.274398, 133.775136], status: 'mrk'},
{name: 'MZFR', coords: [37.090240, -95.712891], status: 'mrk'},
{name: 'AVR', coords: [50.9030599, 6.4213693], status: 'mrk'}
];
$('#world-map-markers').vectorMap({
map: 'world_mill_en',
normalizeFunction: 'polynomial',
markerStyle: {
initial: {
fill: '#F8E23B',
stroke: '#383f47'
}
},
backgroundColor: '#383f47',
markers: plants.map(function(h) {
return {
name: h.name,
latLng: h.coords
}
}),
series: {
markers: [{
attribute: 'image',
scale: {
'mrk': 'marker.png'
},
values: plants.reduce(function(p, c, i) {
p[i] = c.status;
return p
}, {}),
}]
}
});
});

使用空标记和值初始化地图:
mapObj = new jvm.Map({
container: $('#world-map-markers'),
map: 'world_mill_en',
normalizeFunction: 'polynomial',
markerStyle: {
initial: {
fill: '#F8E23B',
stroke: '#383f47'
}
},
backgroundColor: '#383f47',
markers: [],
series: {
markers: [{
attribute: 'image',
scale: {
'mrk': 'marker.png'
},
values: [],
}]
}
});
只是要指出你也可以单独设置标记和值,声明两个数组:
var mapMarkers = [];
var mapMarkersValues = [];
然后,无论你需要点击处理程序,都要调用这样的函数:
function addPlantsMarkers() {
var plants = [
{name: 'VAK', coords: [-25.274398, 133.775136], status: 'mrk'},
{name: 'MZFR', coords: [37.090240, -95.712891], status: 'mrk'},
{name: 'AVR', coords: [50.9030599, 6.4213693], status: 'mrk'}
];
mapMarkers.length = 0;
mapMarkersValues.length = 0;
for (var i = 0, l= plants.length; i < l; i++) {
mapMarkers.push({name: plants[i].name, latLng: plants[i].coords});
mapMarkersValues.push(plants[i].status);
}
mapObj.addMarkers(mapMarkers, []);
mapObj.series.markers[0].setValues(mapMarkersValues);
}

另一种方法是清空地图容器,然后使用标记重新渲染地图。渲染速度很快,并且页面内存得到很好的管理:
function load_map() {
$("#us_map").empty();
$("#us_map").vectorMap({
map: "us_merc_en",
normalizeFunction: "polynomial",
hoverOpacity: .7,
hoverColor: !1,
regionStyle: {
initial: {
fill: "#e3eaef"
}
},
markerStyle: {
initial: {
r: 9,
fill: "#727cf5",
"fill-opacity": .9,
stroke: "#fff",
"stroke-width": 7,
"stroke-opacity": .4
},
hover: {
stroke: "#fff",
"fill-opacity": 1,
"stroke-width": 1.5
}
},
backgroundColor: "transparent",
markers: [{
latLng: [$('#latitude').val(), $('#longitude').val()],
name: $('#address').val()
}]
})
}
