Comment appliquer le survol sur une balise html?

J'essaie de survoler la balise area de HTML. J'ai essayé ceci en CSS:

area:hover
{
    border:1px solid black;
}

C'est le HTML sur lequel il devrait être appliqué.

Alors, comment est-il possible que lorsque je survole la zone, sa couleur de bordure vire au noir ou même au rouge?

Sizzling Code

Ce que j'ai fait est de créer un élément de canevas que je positionne ensuite devant la carte graphique. Ensuite, chaque fois qu'une zone est survolée, j'appelle une fonction qui obtient la chaîne de coordonnées de cette forme et de son type. Si c'est un poly j'utilise les coords pour dessiner un contour sur la toile. Si c'est un rect, je trace un contour rect. Vous pouvez facilement ajouter du code pour traiter les cercles.

Vous pouvez également définir l'opacité de la zone de travail sur moins de 100% avant de remplir le fichier poly/rect/circle. Vous pouvez également changer le recours à un contexte global pour le contexte du canevas, ce qui signifie que vous pouvez gérer plus d’une carte-image sur la même page.

Vous pouvez utiliser jQuery pour y parvenir

Exemple:

$(function () {
        $('.map').maphilight();
    });

Passez par ceci [~ # ~] link [~ # ~] pour en savoir plus.

Si ce qui précède ne fonctionne pas, passez à travers ceci lien.

[~ # ~] éditer [~ # ~] :

Donnez la même classe à chaque balise area comme class="mapping"

et essayez ce code ci-dessous

$('.mapping').mouseover(function() {
    alert($(this).attr('id'));
}).mouseout(function(){
    alert('Mouseout....');      
});

Mr_Green

pour compléter ce script, la fonction pour dessiner un cercle,

    function drawCircle(coordon)
    {
        var coord = coordon.split(',');

        var c = document.getElementById("myCanvas");
        var hdc = c.getContext("2d");
        hdc.beginPath();

        hdc.arc(coord[0], coord[1], coord[2], 0, 2 * Math.PI);
        hdc.stroke();
    }
