Question

我是所有这些东西的新手。我需要在欧洲财务状况上使用SVG创建地图。我得到了所有的数据。地图现在工作正常。我甚至能够在地图的一侧显示国家特定数据，如人口，GDP和所有数据。

但是，当用户将鼠标移动或悬停在特定国家/地区时，我需要将此数据显示为工具提示。就像，显示鼠标悬停数据并将其隐藏在每个国家/地区的鼠标输出事件中。我的代码的一部分在下面。

 <title id="title">Countries of Europe</title>
 <defs><script>
      <![CDATA[

    var country = []; 

    country[0]=["Abbreviation","Name","GDP","Population","Eurozone","Public Debit","Unemployment","Rating"];
    country[117]=["fi","Finland",239,5302545,"yes",48.6,7.6,"AAA"];
    country[118]=["de","Germany",3315,82217800,"yes",81.2,5.6,"AAA"];

    function myShowValues(myEvent)
    {
       var myScrId = myEvent.target.getAttribute('id').replace(/c/,'1'); 
       document.getElementById('myLegCantName').firstChild.data = '' + country[myScrId][1]+ '' ;    
       document.getElementById('gdp').firstChild.data='GDP: ' + country[myScrId][2]+' Billions of $US';
       document.getElementById('unem').firstChild.data='Unemployment: ' + country[myScrId][6]+' %';
       document.getElementById('sp').firstChild.data='S & P rating: ' + country[myScrId][7]+' ';
       document.getElementById('pd').firstChild.data='Public debt: ' + country[myScrId][5]+' % of GDP';
    }

    function changeopa(evt)
    {
       evt.target.setAttribute("opacity", "0.5")
       myShowValues(evt); 
    } 

    function info(evt)
    {
       var box= evt.target;
    }

    ]]>
</script></defs>

然后我正在使用以下这些功能，

<rect id="ocean" x="-371.388" y="-44.213" fill="aliceblue" width="1222.493" height="783.168">
</rect>

<!-- EU Countries Below - arranged in alphabetical order -->

<!-- ISO-3116-1-ALPHA2 code - .de (Germany) -->
<path id="118" fill="#00CC00" stroke="#FFFFFF" stroke-width="0.7"

onmouseout="evt.target.setAttribute('opacity', '1.0');"
