I have following problem I want to dynamically create HTML buttons inside SVG document. At first I look over the SVG document, find apropriate reactangle and replace rectangle with <foreignObject>element. I am able to generate following SVG
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
xmlns:svg="http://www.w3.org/2000/svg"
xmlns="http://www.w3.org/2000/svg"
version="1.1"
width="100%"
height="100%"
viewBox="0 0 93.875076 43.283451"
id="svg20755"
xml:space="preserve">
<g id="Button-1" transform="translate(0.5000775,0.50220189)">
<foreignObject xmlns="http://www.w3.org/2000/svg" x="0" y="0" width="93" height="43">
<body xmlns="http://www.w3.org/1999/xhtml" style="margin: 0px; height: 100%;">
<button type="button" style="width:100%; height:100%;" onclick="alert('Button clicked')">
Juhuhuhu!
</button>
</body>
</foreignObject>
</g>
</svg>
This is the snippet how I create the element
var ns_HTML = 'http://www.w3.org/1999/xhtml';
var ns_SVG = REX.HELPERS.ns_svg;
var element = <Some code to load an SVG element>
var foreignObject = document.createElementNS(ns_SVG, 'foreignObject');
var body = document.createElementNS(ns_HTML, 'body');
body.setAttribute('xmlns', 'http://www.w3.org/1999/xhtml'); // FF
body.style.margin = '0px';
body.style.height = '100%';
var button = document.createElementNS(ns_HTML, 'button');
button.setAttribute('type','button');
button.setAttribute('style','width:100%; height:100%;');
button.innerHTML = 'Test!';
body.appendChild(button);
foreignObject.appendChild(body);
I have two problems especially in Chrome Browser:
<body> did not fill the height of the <foreignObject>
button did not behave as a button (no reaction on mouseover and mousedown)JSFiddle here

I don't know why you say <body> element doesn't fill the height of <foreignObject> !?
When I try now in 2020, I see only a button in midlle on screen.
I have added a SVG <rect> element with same size (width and height) than <foreignObject> to have the possibility to compare these 2 objects.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
xmlns="http://www.w3.org/2000/svg"
version="2.0"
width="100%"
height="100%"
viewBox="0 0 90 50"
>
<g transform="translate(1 0)">
<foreignObject xmlns="http://www.w3.org/2000/svg" x="0" y="0" width="80" height="20">
<body xmlns="http://www.w3.org/1999/xhtml" style="margin:0px; height:100%;">
<button type="button" style="width:100%; height:100%;" onclick="alert('Button clicked')">
Juhuhuhu!
</button>
</body>
</foreignObject>
<rect x="0" y="25" width="80" height="20" stroke="orange" stroke-width="2" fill="white"/>
</g>
As you can see, they have same size !
I put an image to proove what I say because it is possible that in 1 year what I have written is false !
