SVG button affects external div display - html

Question

I am trying to implement the
http://demosthenes.info/blog/760/Create-A-Responsive-Imagemap-With-SVG
to my needs
The problem is that I want the button Ive created to change the style of a div outside the figure tag. I can not find a way to do that.
All I need is by hovering over the .my-1 button, to display the .y1 div
Here is the code so far.
<style type="text/css">
#burj-imagemap {
overflow: hidden;
padding-bottom: 75%;
vertical-align: middle;
width: 100%;
}
#burj-imagemap svg {
display: inline-block;
left: 0;
position: absolute;
top: 0;
}
.my-1:hover {background:#fff; z-index:100; opacity:0.3; filter: alpha(opacity=30); border:1px solid #000;
}
.my-1 {cursor: pointer;}
.y1 {
display: none;
}
.my-1:hover .y1 {
display: block;
background-color: #F00;
height: 250px;
width: 250px;
z-index:1000;
}
</style>
<figure id="burj-imagemap">
<svg preserveAspectRatio="xMinYMin meet" viewBox="0 0 1200 808" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" version="1.1">
<image xlink:href="http://demosthenes.info/assets/images/burj-khalifa.jpg" height="808" width="1200">
</image>
<a class="my-1" >
<g>
<defs>
<polygon id="SVGID_1_" points="322,131 62,240 79,346 274,250 412,405 501,250"/>
</defs>
<clipPath id="SVGID_2_">
<use xlink:href="#SVGID_1_" overflow="visible"/>
</clipPath>
<g clip-path="url(#SVGID_2_)">
<image overflow="visible" width="1200" height="808" xlink:href="http://demosthenes.info/assets/images/burj-khalifa.jpg" transform="matrix(1 0 0 1 -33.5 -301)">
</image>
</g>
</g></a>
</svg>
</figure>
<div class="y1">Hi!</div>
any ideas?

Answer 1

You could include an event handler in the svg like this..
<g clip-path="url(#SVGID_2_)" onmouseover="document.getElementById('y1').style['display'] = 'inline';">
<div id="y1" class="y1">Hi!</div>
