Javascript D3 choropleth州地图数据更新按钮点击

Javascript D3 choropleth州地图数据更新按钮点击,javascript,d3.js,topojson,Javascript,D3.js,Topojson,我已经使用d3、datamaps和topojson创建了一个choropleth状态映射。我在基于按钮单击更改原始地图的数据时遇到问题。首选的方法是在change函数中刷新原始地图的数据。相反,我让按钮执行函数消除包含映射的div,然后重新创建div,然后完全生成一个新映射(请参阅下面的代码)。这是可行的,但我认为有一种更简单、更复杂的方法来刷新数据。任何帮助都将不胜感激 <!DOCTYPE HTML> <html> <head> <scri

我想我能帮上忙。在这种情况下,当您有一些冗余代码时,通常会有一种更简单的方法来完成任务。如果您查看datamaps中的示例和示例,您可以逐一查看它们,以更好地了解地图构建过程的工作原理,这将有助于任何未来的项目

我查看了他们的choropleth和state label示例,以了解如何做到这一点。定义
onclick
属性的方式是正确的。不过,只需渲染贴图一次。要更新它,您可以使用他们的
.updateChoropleth()
方法,如choropleth示例所示。而且,您似乎不需要jQuery。出于某种原因,我在过去尝试同时使用jQuery和d3时遇到了一些问题。在大多数情况下,你可以用d3完成你所需要的。这里有一个链接指向另一个关于该问题的问题:

我创建了一个plunker,以便您可以看到我所做的工作的输出。让我知道这是否是你想要做的:
