渲染地图函数
地图展示三种类型的数据
这里用到的数据是jn,jw,wq
series: [
{
name: "境外隔离人员",
type: "scatter",
coordinateSystem: "geo",
data: jingwai,
zlevel: 9,
symbol: icon1,
symbolSize: 20,
label: {
normal: {
formatter: "{b}",
// position: 'right',
position: "right",
show: true,
fontSize: "16",
},
emphasis: {
show: true,
},
},
itemStyle: {
normal: {
color: "#FFC516",
},
},
},
{
name: "我区隔离人员",
type: "scatter",
coordinateSystem: "geo",
data: woqu,
zlevel: 9,
symbol: icon2,
symbolSize: 20,
label: {
normal: {
formatter: "{b}",
// position: 'right',
position: "right",
show: true,
fontSize: "16",
},
emphasis: {
show: true,
},
},
itemStyle: {
normal: {
color: "#FFC516",
},
},
},
{
name: "江宁隔离人员",
type: "scatter",
coordinateSystem: "geo",
data: jiangning,
zlevel: 9,
symbol: icon3,
symbolSize: 20,
label: {
normal: {
formatter: "{b}",
// position: 'right',
position: "right",
show: true,
fontSize: "16",
},
emphasis: {
show: true,
},
},
itemStyle: {
normal: {
color: "#FFC516",
},
},
},
],
鼠标悬浮在某个定位点，显示相关详情数据；
这里用到的数据其实是datas。params对应的是jn,jw,wq的数据，通过循环datas,匹配前面三个的name,（其实可以直接在jn,jw,wq写入详情值，一开始没设计好，就没有再改接口了）
tooltip: {
padding: 0,
enterable: true,
transitionDuration: 1,
textStyle: {
color: "#000",
decoration: "none",
// fontFamily: "shuzi",
// fontSize: 26
},
extraCssText: "height:auto;line-height: 20px;font-size:26px",
formatter: function (params) {
console.log(params);
if (params.data != undefined) {
var name = params.data.name;
var toolTipDataMap = params.data.data;
var tipHtml = "";
for (var i = 0; i < datas.length; i++) {
var itemName = datas[i].name;
if (name == itemName) {
toolTipDataMap = datas[i].data;
}
}
}
tipHtml =
'<div class="box_bg">' +
'<p>隔离点名称：<span class="value">' +
params.data.name +
" </span><span></span></p></span>" +
'<p>隔离人员总数：<span class="value">' +
toolTipDataMap.glryzs +
" </span><span>人</span></p>" +
'<p>工作人员数量(含酒店工作人员)：<span class="value">' +

'<p>剩余可用房间数：<span class="value">' +

"</div>";
return tipHtml;
},
},
放大缩小限制
scaleLimit: {
min: 0.8,
max: 1.8,
},
整合一下，就是这样的
function rzMapChart(myEchart) {
$.getJSON(mapJson, function (geoJson) {
echarts.registerMap("yuhuatai", geoJson);
/*获取地图数据*/
var mapFeatures = geoJson.features;
myChart.hideLoading();
mapFeatures.forEach(function (v) {
// 地区名称
var name = v.properties.name;
// 地区经纬度
objall[name] = v.properties.center;
});

根据搜索的数据，显示当前的定位点及其相关数据；

//清空地图

//根据人名获取酒店名
