The HTML map tag as well as the js maphilight stopped working

I am making a web page and am using the map tag in it. My coordinates of the areas are correct but it is not working for some reason. I also have used the maphilight library which is not working as well. Also, the same code with different coordinates was working for a different image that I had used, but now it isn't. here is my html code:
<div class="col-md-12">
<img src="/static/Images/Mosaic.png" alt="mosaic" usemap="mosaicMap" id="mosaicImg">
<map name="mosaicMap">
<area shape="rect" coords="0,0,100,100" onclick="selectImage(1)">
<area shape="rect" coords="100,0,200,100" onclick="selectImage(2)">
<area shape="rect" coords="200,0,300,100" onclick="selectImage(3)">
<area shape="rect" coords="0,100,100,200" onclick="selectImage(4)">
<area shape="rect" coords="100,100,200,200" onclick="selectImage(5)">
<area shape="rect" coords="200,100,300,200" onclick="selectImage(6)">
<area shape="rect" coords="0,200,100,300" onclick="selectImage(7)">
<area shape="rect" coords="100,200,200,300" onclick="selectImage(8)">
<area shape="rect" coords="200,200,300,300" onclick="selectImage(9)">
</map>
</div>
My image is 300 x 300 px
The function is not being called on clicking the area. Here is my js code for the maphilight:
$(function() {
$('#mosaicImg').maphilight();
});
Here is the function called:
function selectImage(imageNumber) {
console.log("here");
imageNum = imageNumber;
inputImage.src = "/static/Images/Mosaic" + imageNum.toString() + ".png";
laterNextText();
}
Please help me identify where am I wrong.

image Map with Bootstrap Tooltips not showing in correct spot

I have an image map and I would like to use the built-in tooltips provided by Bootstrap when a user hovers over a specific part of that image.
The issue I'm having is that the tooltip does not show up in the right place. Right now it shows at the top left corner of the image for all areas of the image map.
How can I move the tooltips under their respective areas without having to reposition each tooltip individually? It should automatically be within the rec defined.
Here is the map code I am using:
<img id="Image-Maps-Com-process-map" src="images/osh drawing.png" border="0" width="600" height="600" orgWidth="600" orgHeight="600" usemap="#process-map" alt="" />
<map name="process-map" id="ImageMapsCom-process-map">
<area alt="" title="Wood Burning Stove" href="#" class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="478,186,572,296" style="outline:none;" target="_self" />
<area alt="" title="Rough Cut Lumber" href="#" class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="184,1,395,148" style="outline:none;" target="_self" />
<area alt="This is the description maybe" title="Distributing" href="#"class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="45,398,304,577" style="outline:none;" target="_self" />
<area alt="" title="Shipping Materials" href="#"class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="9,52,141,183" style="outline:none;" target="_self" />
<area alt="" title="Sawdust" href="#"class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="302,311,410,385" style="outline:none;" target="_self" />
<area alt="" title="Electricity" href="#"class="tooltip-bot" data-original-title="Title text here" shape="rect" coords="430,0,570,113" style="outline:none;" target="_self" />
<area alt="manufacturing" title="Manufacturing" href="#"class="tooltip-bot" data-original-title="Title text here" shape="poly" coords="348,193,213,197,188,313,221,368,296,362,300,310,357,302,363,193" style="outline:none;" target="_self" />
</map>

I'm no expert but I feel like this is because the area elements have no actual heights or widths. Their boundaries are established using the coords attribute which likely is not looked at by bootstrap.
There may be a better way to do this, but a simple fix would be to add the below code to your page.This will position the tooltip a fixed distance from the pointer itself.
Here is a working jsFiddle
$(document).mousemove( function(e) {
var mouseX = e.pageX - $('#Image-Maps-Com-process-map').offset().left - 40;
var mouseY = e.pageY - $('#Image-Maps-Com-process-map').offset().top + 20;
$('.tooltip').css({'top':mouseY,'left':mouseX}).fadeIn('slow');
});

I know that this is a fairly old and answered question, but I figured I would throw this in as I ran into the same issue and couldn't find an exact answer elsewhere. I have a site that uses an older asp.net chart control that draws image maps over the graphs so that tooltips can be displayed. To use tooltips on its area attributes and get them in the right places, I used the code below. Note that I still had to use offset amounts, but it worked fairly well. ".maparea" is a class that is dynamically applied to all of the map area attributes. I also used mouseover as I did not need the tooltip to move around constantly.
$('.maparea').mouseover(function (e) {
var position = $(this).attr('coords').split(',');
x = +position[0];
y = +position[1];
$('.tooltip').css({ 'top': y + 60, 'left': x - 83 }).fadeIn('slow');
$('.tooltip-arrow').css({ 'left': '50%' });
});
Edit:
I had to put in the tooltip-arrow line because Google Chrome was messing up the alignment of the tooltip arrow. Don't think this will happen in all scenarios but since my page has menus that can be collapsed that will resize the page on their own, they were throwing the alignment off.

My solution for popovers (basing on mouse click position):
var clickTop,clickLeft=0;
$(document).click(function(e){
clickTop =e.pageY;
clickLeft =e.pageX;
});
$().ready(function(){
var popovers=$('[data-toggle="popover"]');
popovers.popover({
placement: 'bottom center',
html:true,
trigger:'focus'
}).on("shown.bs.popover", function(e){
$('.popover').css({top:clickTop,left:clickLeft-100});
})
});

I've adopted #Big EMPin solution (right area tooltips), so it works for me at last:
<div style="position: relative;display: inline-block">
<img style="max-width: 100%" src="../static/img/JavaPyramid.jpg" usemap="#courses">
</div>
<map name="courses">
<area shape="rect" coords="120,10,200,85" href="/view/startjava" data-toggle="tooltip" data-placement="right" title="StartJava" class="maparea">
<area shape="rect" coords="85,100,165,175" href="/view/basejava" data-toggle="tooltip" data-placement="right" title="BaseJava" class="maparea">
<area shape="rect" coords="50,190,130,265" href="/view/topjava" data-toggle="tooltip" data-placement="right" title="TopJava" class="maparea">
<area shape="rect" coords="20,280,100,355" href="/view/masterjava" data-toggle="tooltip" data-placement="right" title="MasterJava" class="maparea">
</map>
<script>
$('.maparea').mousemove(function (e) {
var pos = $(this).attr('coords').split(',');
$('.tooltip').css({'left': parseInt(pos[2]) + 5, 'top': parseInt(pos[1]) + 35}).fadeIn('slow');
});
</script>

Can I have an onclick event on a imagemap area element?

I would like to put an onclick event on an area element. Here is my setup:
<img id="image" src="wheel.png" width="2795" height="2795" usemap="#Map" >
<map name="Map">
<area class="blue" onclick="myFunction()" shape="poly" coords="2318,480,1510,1284" href="#">
</map>
I have tried 2 different ways to have an onclick event. Firstly i tried this:
$(".blue").click( function(event){
alert('test');
});
I have also tried this:
function myFunction() {
alert('test');
}
Neither of the above work. Do area elements support the above, or do they only support having a href?

Pay attention:
Attribute href is obligatory, without it the area-tag does nothing!
To add a click event, you'll need to block default href.
Your code should start as follows:
$(".blue").on("click", function(e){
e.preventDefault();
/*
your code here
*/
});
Live example here.

Its the shape that's the problem. Your code has set shape equal to polygon but only has 4 points in the coordinates attribute. You need to set shape to rectangle instead.
Set shape="rect" like this:
<img id="image" src="wheel.png" width="2795" height="2795" usemap="#Map" >
<map name="Map">
<area class="blue" onclick="myFunction()" shape="rect" coords="2318,480,1510,1284" href="#">
</map>

Use a class for all elements you want to listen on, and optionally an attribute for behavior:
<map name="primary">
<area shape="circle" coords="75,75,75" class="popable" data-text="left circle text">
<area shape="circle" coords="275,75,75" class="popable" data-text="right circle text">
</map>
<img usemap="#primary" src="http://placehold.it/350x150" alt="350 x 150 pic">
<div class='popup hidden'></div>
Then add your event listeners to all elements in the class:
const popable = document.querySelectorAll('.popable');
const popup = document.querySelector('.popup');
let lastClicked;
popable.forEach(elem => elem.addEventListener('click', togglePopup));
function togglePopup(e) {
popup.innerText = e.target.dataset.text;
// If clicking something else, first restore '.hidden' to popup so that toggle will remove it.
if (lastClicked !== e.target) {
popup.classList.add('hidden');
}
popup.classList.toggle('hidden');
lastClicked = e.target; // remember the target
}
Demo: https://codepen.io/weird_error/pen/xXPNOK

Based on your comments, you just need this:
$("#image").click( function(){
alert("clicked");
//your code here
});
Demo:
http://codepen.io/tuga/pen/waBQBZ

This is a simple one:
<area class="blue" onclick="alert('test');" shape="poly" coords="2318,480,1510,1284" href="#">
Or for any other code:
<area class="blue" onclick="//JavaScript Code//" shape="poly" coords="2318,480,1510,1284" href="#">

Try :
<img src="wheel.png" width="2795" height="2795" alt="Weels" usemap="#map">
<map name="map">
<area shape="poly" coords="2318,480,1510,1284" alt="otherThing" href="anotherFile">
</map>
You souldn't want to add onClick events on area, documentation :
The tag defines an area inside an image-map (an image-map is an image with clickable areas).
Edit : your coords are a bit weird since its supposed to the couples of each vertices (so right now, your polygon is a line)

I found this question by #TimorEranAV
HTML map that displays text instead of linking to a URL
and was marked as duplicate, but i think what he was expecting is this,
<html>
<head>
<title> Program - Image Map</title>
</head>
<body>
<img src="new.png" width="145" height="126" alt="Planets" usemap="#planetmap">
<map name="planetmap">
<area shape="rect" coords="0,0,82,126" href="sun.htm" alt="Sun" title = "Sun">
<area shape="rect" coords="82,0,100,126" href="mercur.htm" alt="Mercury" title = "Mercury">
</map>
</body>
</html>
Here the title tag gives the opportunity to add a hover text(tip) to the image map.

JS Math.random doesn't get -9-

The code is working for all the areas and figures, except when the variable id equals 9. Then the #10 image (#9 index) doesn't appear, an undefined message is written instead. When id equals any other number, the checkAnswer() function alert correct or wrong for every area clicked, except for the #10 area, which doesn't alert anything. What's wrong with the code? (the images are all correctly on the directory)

If it is indeed only happening on item #9, it suggests to me some type of number verses string problem.
First change the variable name of 'id' to something else, that name could cause problems.
Then declare it at the top with a var, the same as you are doing with the cobras array.
I would change 'id' to a string, and convert the result of the Math function using parseInt.
Change the index values you are giving in the array to strings as well, so they become keys instead.
Then add single quotes around the value given in the checkAnswer calls from the area tags.
No guarantee that this would fix the problem, but at least you know for sure that the random item, and the item chosen, are all strings.

Get img tag id when click on map area of this image

I have some images-figures with map-area like this
and i need get image id when click inside area zone
can i made it without custom area functional realisation with js?
UPD sandbox
UPD2 found second, other problem.
first area zone (red), which covered by second image not clickable and z-index for area not working.
FINAL UPD
I wrote small custom function for mapping some objects.
Maybe it will help someone:

I hope this is what you are looking for

}
});
}

Like so assuming you can use jQuery:
<img id="planetsimg" src="planets.gif" width="145" height="126" alt="Planets" usemap="#planetmap">
<map name="planetmap">
<area shape="rect" coords="0,0,82,126" href="sun.htm" onclick="clicked(this)" alt="Sun" image-id="planetsimg">
<area shape="circle" coords="90,58,3" href="mercur.htm" onclick="clicked(this)" alt="Mercury" image-id="planetsimg">
<area shape="circle" coords="124,58,8" href="venus.htm" onclick="clicked(this)" alt="Venus" image-id="planetsimg">
</map>
<script>
function clicked(map) {
var image = $('#' + $(map).attr('image-id'));
alert('img ' + image + ' clicked map ' + $(map).attr('href'));
return false; // Prevents href from opening normally. Return true if you want the link to open
</script>

just add the clickhandlers to the areas (images) of your map, not to the map itself
if you are using jQuery, you can do it like that:
$('map').find('area').each(function() {
$(this).on('click',...
});
