我想在我的网站上添加一张世界地图。我的问题是在第一次加载页面时一切正常，但是当我在页面上的视图之间切换时，世界地图加载时没有标记，看起来地图无法在角度路由中完全加载。 我该怎么做才能重装？ 提前谢谢。

Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core The bulk of this conurbation forms the Greater London administrative area (coterminous with the London region), governed by the Mayor of London and the London Assembly.</p>";

答案 0 :(得分：1)
AmCharts.ready相当于window.onload，因此在这种情况下它没用，因为您的代码只会运行一次。摆脱ready调用并让自己的forEach代码独立运行将使其工作。您也不希望在添加每个图片后调用validateData，因为它会减慢进程速度 - 只需在forEach完成后调用一次。
我不确定为什么你在makeChart之后运行你的forEach代码，你可以先创建图像并将它分配给makeChart调用本身的images数组。如果您必须在初始化地图时运行图像设置代码，请将其放在地图的init事件中：
var map = AmCharts.makeChart("chartdiv", {
// ..
listeners: [
{
event: "init",
method: function(e) {
var map = e.chart;
// populate the city dropdown when the page loads
relevantcities.forEach(function(arrayItem) {
var city = arrayItem;
city.svgPath = targetSVG;
city.zoomLevel = 3;
city.scale = 1.2;
city.label = city.title + " +25%";
city.color = "green";
// add city object to map
map.dataProvider.images.push(city);
});
map.validateData();
}
}
]
});
