首页 > 解决方案 > 基于美国位置的纬度和经度的 Highmap 不支持 highmap.js 文件

问题描述

我们已经在 web 应用程序中使用 highcharts。下载 highmaps,我们正在为同一应用程序实现 highmaps,我们的要求是美国地图应该根据纬度和经度值显示。我们浏览了下面的链接并实现了它并按预期工作,但在浏览器控制台中出现了一些脚本错误,它似乎 highmap.js 与 highchart.js 文件冲突。

var H = Highcharts,
    map = H.maps['countries/us/us-all'],
    chart;

// Add series with state capital bubbles
$.getJSON('https://cdn.jsdelivr.net/gh/highcharts/highcharts@v7.0.0/samples/data/us-capitals.json', function (json) {
    var data = [];
    $.each(json, function () {
        this.z = this.population;
        data.push(this);
    });

    chart = Highcharts.mapChart('container', {
        title: {
            text: 'Highmaps lat/lon demo'
        },

        tooltip: {
            pointFormat: '{point.capital}, {point.parentState}<br>' +
                'Lat: {point.lat}<br>' +

如果您删除 highchart.js 脚本引用,它将起作用并显示地图,但我们需要用于条形图等的 highchart.js 用于现有的聊天功能对我们不起作用。

我们正在使用下面的 js 文件。proj4.js highmaps.js us-all.js

我下载了 highmaps 文件并将 highmaps.js 、 proj4.js 和 us-all.js 添加到我的项目中并遇到了上述问题。

highchart 和 highmap 应该在同一个 Web 应用程序中工作。js 文件不应冲突,也不应在控制台中显示任何脚本错误。

解决方案


而不是像这样加载 Highcharts 和 Highmaps(问题的 JSFiddle):

<script src="https://code.highcharts.com/maps/highcharts.js"></script>
<script src="https://code.highcharts.com/maps/highmaps.js"></script>

加载 Highcharts,然后加载地图模块(JSFiddle):

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/maps/modules/map.js"></script>
