AMCHARTS交互式地图:使所选州成为可单击的链接

Question

我正在创建一个个人博客网站。我偶然发现了一个交互式访问状态地图，我想在我的一个 html 页面中实现该地图。我能够使用他们提供的生成的 html 成功地将其放在我的网站上。但是，我想稍微调整一下，但我并不完全熟悉javascript。

我想补充两件事：

第一：使选定的状态链接到特定的 html 页面。第二(可选(：单击未突出显示(已访问(的状态时禁用缩放和颜色更改。

这是我目前拥有的代码：

<script src="https://www.amcharts.com/lib/3/ammap.js" type="text/javascript"></script>
<script src="https://www.amcharts.com/lib/3/maps/js/usaHigh.js" type="text/javascript"></script>
<script src="https://www.amcharts.com/lib/3/themes/light.js" type="text/javascript"></script>
<div id="mapdiv" style="width: 1000px; height: 450px; display: block; margin-left: auto; margin-right: auto; margin-top: 100px; cursor: default;"></div>
<script type="text/javascript">
var map = AmCharts.makeChart("mapdiv", {
type: "map",
theme: "light",
backgroundColor : "#FFFFFF",
backgroundAlpha : 1,
zoomControl: {
zoomControlEnabled : false
},
dataProvider : {
map : "usaHigh",
getAreasFromMap : true,
areas :
[
	{
		"id": "US-AZ",
		"showAsSelected": true
	},
	{
		"id": "US-CA",
		"showAsSelected": true
	},
	{
		"id": "US-DC",
		"showAsSelected": true
	},
	{
		"id": "US-ID",
		"showAsSelected": true
	},
	{
		"id": "US-MA",
		"showAsSelected": true
	},
	{
		"id": "US-MT",
		"showAsSelected": true
	},
	{
		"id": "US-NJ",
		"showAsSelected": true
	},
	{
		"id": "US-NV",
		"showAsSelected": true
	},
	{
		"id": "US-NY",
		"showAsSelected": true
	},
	{
		"id": "US-OR",
		"showAsSelected": true
	},
	{
		"id": "US-PA",
		"showAsSelected": true
	},
	{
		"id": "US-WA",
		"showAsSelected": true
	},
	{
		"id": "US-WY",
		"showAsSelected": true
	}
]
},
areasSettings : {
autoZoom : true,
color : "#B4B4B7",
colorSolid : "#DB4646",
selectedColor : "#DB4646",
outlineColor : "#666666",
rollOverColor : "#9EC2F7",
rollOverOutlineColor : "#000000"
}
});
</script>

Answer 1

可以将 url 属性添加到要链接到的状态。如果要在新选项卡/窗口中打开链接，还可以将urlTarget设置为 "_blank"：

areas: [{
    "id": "US-AZ",
    "showAsSelected": true,
    "url": "http://az.gov",
    "urlTarget": "_blank"
  },
  {
    "id": "US-CA",
    "showAsSelected": true,
    "url": "http://ca.gov/",
    "urlTarget": "_blank"
  },
  // ... etc

我还建议在areasSettings中将autoZoom设置为 false，将selectable设置为 true，以便地图在触发 URL 之前不会尝试缩放：

  areasSettings: {
    autoZoom: false,
    selectable: true,

要禁用其他状态的缩放和颜色更改，只需从dataProvider中删除getAreasFromMap: true即可。

var map = AmCharts.makeChart("mapdiv", {
  type: "map",
  theme: "light",
  backgroundColor: "#FFFFFF",
  backgroundAlpha: 1,
  zoomControl: {
    zoomControlEnabled: false
  },
  dataProvider: {
    map: "usaHigh",
    areas: [{
        "id": "US-AZ",
        "showAsSelected": true,
        "url": "http://az.gov",
        "urlTarget": "_blank"
      },
      {
        "id": "US-CA",
        "showAsSelected": true,
        "url": "http://ca.gov/",
        "urlTarget": "_blank"
      },
      {
        "id": "US-DC",
        "showAsSelected": true
      },
      {
        "id": "US-ID",
        "showAsSelected": true
      },
      {
        "id": "US-MA",
        "showAsSelected": true
      },
      {
        "id": "US-MT",
        "showAsSelected": true
      },
      {
        "id": "US-NJ",
        "showAsSelected": true
      },
      {
        "id": "US-NV",
        "showAsSelected": true
      },
      {
        "id": "US-NY",
        "showAsSelected": true
      },
      {
        "id": "US-OR",
        "showAsSelected": true
      },
      {
        "id": "US-PA",
        "showAsSelected": true
      },
      {
        "id": "US-WA",
        "showAsSelected": true
      },
      {
        "id": "US-WY",
        "showAsSelected": true
      }
    ]
  },
  areasSettings: {
    autoZoom: false,
    selectable: true,
    color: "#B4B4B7",
    colorSolid: "#DB4646",
    selectedColor: "#DB4646",
    outlineColor: "#666666",
    rollOverColor: "#9EC2F7",
    rollOverOutlineColor: "#000000"
  }
});
