javascript - amcharts 交互式 map : making selected states a clickable link

Question

我正在创建一个 personal blog site .我偶然发现了一个交互式访问状态 map ，我想在我的一个 html 页面中实现它。我能够使用他们提供的生成的 html 成功地将它放在我的网站上。但是，我想稍微调整一下，但我对 javascript 并不熟悉。

我想补充两点:

第 1 步:将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

您可以添加 url属性到您想要链接到的状态。您还可以设置 urlTarget "_blank" 如果你想让链接在新标签页/窗口中打开:

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

我还建议设置 autoZoom假和selectable在 areasSettings 中设置为 true，这样 map 就不会在触发 URL 之前尝试缩放:

  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。

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"
  }
});
