我正在显示带有分类区域的美国地图。地图很好但我无法使用Highmap中的工具提示显示Json文件中的值。
这是我的代码：
$.getJSON('../production/UsMapData/UsaMapData.json', function (data) {
$.each(data, function () {
this.code = this.code.toUpperCase();
});
Highcharts.mapChart('geoMap', {
chart: {
type: 'map'
},
title: {
text: 'US'
},
legend: {
enabled: true
},
/* plotOptions: {
map: {
allAreas: false,
joinBy: ['hc-a2', 'code'],
dataLabels: {
enabled: true,
color: '#FFFFFF',
formatter: function () {
if (this.point.properties && this.point.properties.labelrank.toString() < 5) {
return this.point.properties['iso-a2'];
}
},
format: null,
style: {
fontWeight: 'bold'
}
},
mapNavigation: {
enabled: true,
enableButtons: false
},
mapData: Highcharts.geojson(Highcharts.maps['countries/us/us-all']),
tooltip: {
headerFormat: '',
pointFormat: '{point.name}: <b>{series.name}</b>'
}
}
},*/

// return this.point.properties['hc-a2'];
return this.point.code;
// }
},

},

}
}
},

},
cursor: 'pointer',
series: [{

}),
},{

data: $.map(['RI','SC','SD','TN','TX','UT','VT','VA','WA','WV','WI','WY'], function (code) {
return { code: code };
})
}]
});
});
这是Json文件：

地图按预期使用分类区域，但主要是我无法显示json数据。
答案 0 :(得分：1)
目前您的系列数据设置为：
data: $.map(['NC','ND','OH','OK','OR','PA'], function (code) {
return { code: code };
})
这意味着数据只是一个只包含code变量的对象数组。 views（来自json对象）永远不会放入您的系列数据中，因此永远不会包含在Point之后的结果joinBy中。
基本上，您还必须包含views，例如grep而不是map。例如，使用辅助函数：
function getAreasByCode(arrayOfData, arrayOfCodes) {
return $.grep(arrayOfData, function(entry) {
return arrayOfCodes.indexOf(entry.code) >= 0;
});
}
新系列数据规范：
data: getAreasByCode(data, ['AL', 'AK', 'AR', 'AZ','CA','CO','CT'])
请参阅其中的this JSFiddle example。
