SVG 文档中的 HTML 按钮

Question

I have following problem I want to dynamically create HTML buttons inside SVG document.我有以下问题我想在 SVG 文档中动态创建 HTML 按钮。 At first I look over the SVG document, find apropriate reactangle and replace rectangle with <foreignObject> element.首先我查看 SVG 文档，找到合适的 reactangle 并用<foreignObject>元素替换矩形。 I am able to generate following SVG我能够生成以下 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这是我如何创建元素的片段

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:我有两个问题，尤其是在 Chrome 浏览器中：

The element <body> did not fill the height of the <foreignObject>元素<body>没有填充<foreignObject>的高度
~~The button did not behave as a button (no reaction on mouseover and mousedown)~~ (It seems that this was fixed in new release of Chrome and Firefox) ~~该 button行为不像按钮（鼠标悬停和鼠标按下时没有反应）~~ （这似乎在 Chrome 和 Firefox 的新版本中已修复）

I don't know why you say <body> element doesn't fill the height of <foreignObject> !?我不知道你为什么说<body>元素没有填充<foreignObject>的高度！？

When I try now in 2020, I see only a button in midlle on screen.当我现在在 2020 年尝试时，我在屏幕上只看到中间有一个按钮。

I have added a SVG <rect> element with same size (width and height) than <foreignObject> to have the possibility to compare these 2 objects.我添加了一个与<foreignObject>具有相同大小（宽度和高度）的 SVG <rect>元素，以便比较这两个对象。

<?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 !如您所见，它们的大小相同！

I put an image to proove what I say because it is possible that in 1 year what I have written is false !我放了一张图片来证明我所说的话，因为我所写的可能在 1 年内是假的！
