Using Jquery Hover with HTML Image Map

Using JQuery hover with HTML image map

You should check out this plugin:

https://github.com/kemayo/maphilight

and the demo:

http://davidlynch.org/js/maphilight/docs/demo_usa.html

if anything, you might be able to borrow some code from it to fix yours.

jquery image map hover effects

You need to understand what <map> means, it's a simple definition on the click areas of an image

saying $(this).css('border','1px solid #FF0000'); you are telling to make the <map> have a solid border, but <map> is just like the <head> elements, it only contains definitions.

To make the borders in the areas, you really need to have 2 images instead.

Jquery: mouseover event on image map area

I just tried your code in Safari and it works just as intended. 2 separate areas that give out separate alerts. One is alerting "qdk" and other "undefined", as you don’t have an ID attribute for the second map.

Hover effect over a poly image map using jquery and html/css

Here are some of the solutions. Still working on the rest (*the map is not aligned correctly, but that's an easy fix).

Update:

Ok, here's some more: There's no way to easily do what you are talking about. You have to use a canvas and actually draw the polygons on the canvas

Image map on mouse over show div

I assume you want the popup effet.

Please see a demo I've prepared for you using your markup

Here's the working jQuery

var $popup = $('.popup');
$('area').on({
  mouseover : function(e){
    var $this = $(this),
        $obj = $('#'+$this.prop('alt'));

    $popup.text($obj.text()).css({
      top: e.pageY + 25,
      left: e.pageX - ($popup.width()/2),
    }).show();
  },
  mouseout: function(){
    var $this = $(this),
        $obj = $('#'+$this.prop('alt'));    

    $popup.hide(0).empty();
  }
});

change image on hover with image map

an idea would be to use the same listener for all the images then have a switch statement that will check the parameter that is passed in and highlight the corresponds image, right now it work, the xyou're passing is throwing an error because it doesn't exists. also you'll need a mouseleave listener to remove the highlighting.

Demo

function mouseover(x) {  switch (x) {    case 'facebook':      {        document.getElementById("imageid").src = "https://i.imgur.com/p5oiGSO.jpeg";      };      break;    case 'instagram':      {
      };      break;    case 'twitter':      {
      };      break;      // etc...     default:      ;      break;  }
}
// reset the image when the user isn't hovering.function mouseleave() {  document.getElementById("imageid").src = "https://i.imgur.com/FTAtJutl.jpg";}

<img id="imageid" src="https://i.imgur.com/FTAtJutl.jpg" alt="Sample Image" usemap="#Map" /><map name="Map" id="Map">    <area alt="facebook" title="" shape="poly" coords="177,214,193,277,475,212,466,149" onmouseover="mouseover('facebook')"onmouseleave="mouseleave()"        />        <!--        <area alt="twitter" title="" shape="poly" coords="177,214,193,277,475,212,466,149" onmouseover="mouseover('twitter')"onmouseleave="mouseleave()"        />        <area alt="instagram" title="" shape="poly" coords="177,214,193,277,475,212,466,149" onmouseover="mouseover('instagram')"onmouseleave="mouseleave()"        />     etc                --></map>
