我有一个使用标准Visual Studio 2017的工作网站。它由一个C＃后端和一个API组成，用于根据用户从jQuery UI中选择的设置请求在HighMaps中显示数据。由于我不喜欢我的Windows机器，几乎和我的Mac一样，我想我会尝试使用.Net Core 2.0 - 从而消除了对我的Windows笔记本电脑的需求。一切都进行得非常顺利（Kudos对微软），但由于某种原因调用API的jQuery代码，返回的数据不会像应该的那样被推送到地图中。
下面是运行的jQuery代码 - alert（）确实显示了JSON数据，但它从未反映在地图中。如果需要，我可以发布HTML或CSS，但是现在我已经包含了head和script部分。
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Great Locations</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript" src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.1.1.min.js"></script>

<script type="text/javascript" src="https://code.highcharts.com/mapdata/countries/us/us-all-all.js"></script>
</head>
这是jQuery代码：
<script type="text/javascript">

/* if user selected a single value (not a range), adjust text to fit */
$(this).parent().children(".slider-range").text(climateSteps[ui.values[0]]);

地图中出现的所有内容都是我硬编码的两个县（以显示地图工作正常）。我想知道是否有一些我需要添加到NuGet或SDK Dependencies中的软件包，但是工作量很大，我不知道缺少什么。我还没想出如何在Mac Visual Studio中显示控制台，所以如果有任何线索，我还没有看到它们。
非常感谢Highcharts支持团队 - 这个问题的最终答案是Mac Visual Studio .Net Core框架出于某种原因与运行经典Visual Studio的Windows平台不同。以下是对我有用的答案：
我需要在带有.Net Core的Mac Visual Studio中使用它 - 不需要JSON.parse（d）：
$("#map-container").highcharts().series[0].update({
data: d
});
而不是这个，适用于Windows全面的Visual Studio（社区版）：
$("#map-container").highcharts().series[0].update({
data: JSON.parse(d)
});
