I want to add tooltip to svg element. Have tried base CSS and Javascript


I have a school project where I have to make a "treasure" map. My idea was to get a world map as a SVG elements with countries and continents. I got the map where every country has its border as elements. I tried to create tooltip with vanilla CSS but with no results and have googled couple of javascript and jquery solutions for tooltips but got no results. I was wondering if its even possible because I'm kinda losing hope already.

I tried using this piece of jquery for tooltip

js file:

(function() {
var infoElem = $('.info');
infoElem.each(function() {
    var self = $(this),
        selfTooltiptext = self.data('tooltip-text');
    if (selfTooltiptext) $('<span/>', {class: 'tooltip', text: selfTooltiptext}).appendTo(self);
});

})();

SVG path in html:

<a href="#" class="info" data-tooltip-text="Hint">
    <path d="M1113.7 124.6l0.9 1-2.6 3.4 2.4 5.6-1.6 1.9-3.8-0.1-4.4-2.2-2.1-0.7-3.8 1-0.1-3.5-1.5 0.8-3.3-2.1-1-3.4 5.5-1.7 5.6-0.8 5.1 0.9 4.7-0.1z" id="EE" name="Estonia">
    </path>
        </a>

CSS:

.tooltip {
display: block;
position: absolute;
left: 0;
bottom: 120%;
width: 190px;
padding: 5px;
border-radius: 10px;
background-color: cadetblue;
color: #fff;
line-height: normal;
text-transform: none;
font-size: 12px;
opacity: 0;
transform: scaleY(0);
transition: all 0.2s ease;
}

.tooltip:after {
    position: absolute;
    content: '';
    left: 10px;
    bottom: -5px;
    width: 0;
    height: 0;
    border-top: 5px solid burlywood;
    border-right: 5px solid transparent;
    border-left: 5px solid transparent;
}

.info:hover .tooltip {
    opacity: 1;
    transform: scaleY(1);
}

Solution

  • You can use the system SVG tooltip <title> which pops up when you hover over a specific area

    <svg version="1.1"
           id="svg2"  xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="467 -284 959 593" xml:space="preserve">
    <g>    
        <title>   "NV" - Nevada
          State capital city - Carson City
          Population
          City  55,274
          Estimate Estimate (2018)  55,414
          </title>
          <path fill="dodgerblue"  id="NV" class="state1" d="M663.4-98.4
            L639.8,30.4l-1.8,0.3l-1.6,2.4l-2.4,0l-1.5-2.7l-2.6-0.4l-0.8-1.1l-1-0.1l-2.8,1.6l-0.3,6.8l-0.4,5.8l-0.3,8.6l-1.4,2.1l-2.4-1.1
            L551.3-51.5l19-67.6L663.4-98.4z"/>
    </g>    
    </svg>  

    Below is an example of a map of several USA states

    When you hover over a certain area of the map, it enlarges and a tooltip with text pops up

    document.querySelectorAll('path.state1').forEach(path => {
      path.addEventListener('mouseover', e => {
        path.parentNode.parentNode.append(path.parentNode);
      });
    });
    .state1 {
    fill:white;
    stroke:dodgerblue;
    transform-origin: center center;
    transform-box: fill-box;
    transition:  1s;
    }
    
    :hover.state1 {
     fill:dodgerblue;
     stroke:white;
     stroke-width:2px;
     filter:url(#dropshadow);
      -webkit-transform: scale(1.5);
     transform: scale(1.5);
     
     }
    <body>
       <section id="map">
