向 raphael JS 世界地图中的国家/地区添加点击操作

Question

我正在制作一张世界地图，您可以在其中使用 raphaeljs 和 world.js 形状单击一个地区（北美、亚洲等）

@David Noël 开源了一个way of combining countries into one element，它会在您翻转时突出显示，我已经成功完成了。

我通常可以使用 Javascript，但我不知道如何为这些区域创建点击事件，因此会为每个区域弹出一些相关信息。我认为上面的 Davids 链接中可能有答案，但我不完全理解文档

你可以在这里看到我到目前为止的进展..http://thetally.efinancialnews.com/tallyassets/mapareas/index.html

Answer 1

好的，所以在亲自联系 David Noel 后，他帮我解答了问题。

在任何地方初始化时，我使用国家代码创建了国家组......

 <script src="anywhere.js"></script>
<script type="text/javascript">
  var aw = new Anywhere(
    document.getElementById('map_div'),
    {

},

..然后我的自定义 JS 文件看起来像这样...

// JavaScript Document

$( document ).ready(function() {


function changeChart() {

console.log('change');

if (dataSet == 1) {

var bank11 = 14
var bank12 = 74
var bank13 = 74

var bank21 = 45
var bank22 = 78
var bank23 = 111

var bank31 = 35
var bank32 = 75
var bank33 = 86 

} else if (dataSet == 2) {

var bank11 = 34
var bank12 = 74
var bank13 = 124

var bank21 = 45
var bank22 = 38
var bank23 = 211

var bank31 = 35
var bank32 = 15
var bank33 = 86 

}


$('.column1 .block1').animate({ 'height' : bank11 });
$('.column1 .block2').animate({ 'height' : bank12, 'bottom' : bank11 });
$('.column1 .block3').animate({ 'height' : bank13, 'bottom' : bank12+bank11  });

$('.column2 .block1').animate({ 'height' : bank21 });
$('.column2 .block2').animate({ 'height' : bank22, 'bottom' : bank21 });
$('.column2 .block3').animate({ 'height' : bank23, 'bottom' : bank22+bank21  });

}   


var dataSet = 0;


eve.on('aw:click', function (identifier, groupKey) {


if (groupKey == 'EMEA'){
dataSet = 1;
} 

if (groupKey == 'ASIA'){
dataSet = 2;
} 

changeChart();


console.log('you clicked ' + identifier +', in '+ groupKey);

$('.'+groupKey).css({"background-color":'#345'});

});


});

Answer 2

希望我不会太晚^^' 好吧，经过一点“检查元素”之后，我只是为路径添加了一个点击侦听器，然后我获取了 id 或名称或任何时候......

只需添加：

  $('path').click(function() {
             console.log(this.id);
             //do what you want with the id, name...you can make an ajax 
             call or anything you want
        }); 

如果你想要一个完整的例子，你可以去：

window.onload = function () {
    // Create canvas and define attributes shared by all paths.
    var R = Raphael("container", 620, 690),
      attr = {
      "fill": "#b9b9b9",
      "stroke": "#fff",
      "stroke-miterlimit": "4",
      "stroke-width": "1",
      "transform": "s0.06,0.06,60,0" // Scales the path to a useful size.
    }; 
    // Define map object. 
    var africaMap = {};
    for (var nation in africaPaths) {
      // Draw a path, then apply attributes to it.
      africaMap[nation] = R.path(africaPaths[nation]).attr(attr);
      // Name the internal Raphael id after the africaPaths property name.
      africaMap[nation].id = nation;

      // Name the element id after the africaPaths property name.
      africaMap[nation].node.id = nation;
    }
    // For an example of interaction via Raphael, uncomment the line below.
   var demo1 = R.getById('tanzania').attr({"fill": "green"});
   $('path').click(function() {
             console.log(this.id);
             // here you do what you want ^^
        });  

  };

希望这对某人有所帮助，对不起我的英语。
