我想知道是否有人可以告诉我我的代码中有什么问题？我希望能够使用传单和高图选择多边形并在弹出窗口中显示图形。我已经设法在弹出窗口中创建了图形，但是它上面缺少这一行，而且我还得到了一个单独的div，它显示了我不想要的网页底部的相同图表（和行）。任何人都可以告诉我如何在弹出窗口的图表上显示该行并删除单独的图表？这是我的code.enter代码

您不需要HTML标记中的div元素。您可以在onEachFeature函数中动态创建一个并将其添加到弹出窗口中。此外，您需要在弹出窗口打开后初始化您的高图，而不是之前。在包含评论的代码中：
new L.GeoJSON(feature, {
onEachFeature: function (feature, layer) {
// Create div with class name highchart
var div = L.DomUtil.create('div', 'highchart');
// Bind popup to layer with div as content
layer.bindPopup(div);
// Handle event when popup opens
layer.on('popupopen', function (e) {
console.log(e.target); // layer object
console.log(e.target.feature); // layer's feature object
console.log(e.popup); // popup object
console.log(e.popup.getContent()); // the div
// Now do the highcharts stuff
Highcharts.chart(e.popup.getContent(), { /**/ });
});
}
});
不要忘记用CSS设置div的维度：
.highchart {
width: 500px;
height: 200px;
}
