我在Safari上的SVG的foreignObjects元素有问题。我正在使用SVG元素以及正在使用的d3.js库。
我所做的是在画布上附加一个foreignObject元素,因为与rect或其他SVG元素不同,不允许将html元素放入其中。现在,经过几天的开发,我注意到Safari似乎不允许将html元素放在foreignObject中。更好的是,它允许执行此操作,并且一切似乎都可以根据检查器进行,但是我放置在foreignObject中的背景设置了。
结果是,我可以在画布内正确地拖动ForeignObject和div,但是与Chrome或Firefox不同,div的背景停留在画布的左上角,而不是div。
在下面,我将粘贴到画布上的样式和异物代码的一部分粘贴
SVG

仅此而已。我认为我正在做Safari不喜欢的事情。但是问题是..什么?
答案 0 :(得分:11)
在position: "fixed"
内的div
上设置foreignObject
固定了我在Safari(以及iOS的Chrome)上的foreignObject位置。
答案 1 :(得分:1)
我发现您需要插入<body>
元素才能使其在Safari中正常工作,如下所示:
<foreignObject width="170" height="28">
<body xmlns="http://www.w3.org/1999/xhtml">
<div>my content</div>
</body>
</foreignObject>
答案 2 :(得分:1)
您可以在SVG中使用<image>
element而不是<foreignObject>
。这样可以轻松解决规模和位置问题,从而避免Safari上的<foreignObject>
错误
请记住将src属性更改为href。
答案 3 :(得分:0)
尝试将您的foreignObjects包装在组元素中。我发现尝试在转换中对foreignObjects进行样式设置在Safari中效果不佳。同样,大多数SVG在Firefox的canvas元素中也不起作用。
<g transform="translate(304,215)rotate(-174.86597769360367)">
<foreignObject>
<div> whatever in here </div>
<foreignObject>
</g>
答案 4 :(得分:0)
尝试为width
添加内联height
和foreignObject
。这似乎可以在Safari上使用。
<foreignObject style="overflow: visible;" y="0" x="0" width="240" height="160">
<div class="info-panel" xmlns="http://www.w3.org/2000/xmlns/" >
<div class="panel-text" xmlns="http://www.w3.org/2000/xmlns/">
<h1>ForeignObject</h1>
<p>For this to work in Safari try adding in a width and height inline on the foreignObject element. The background will also expand to the more text you add.</p>
</div>
</div>
</foreignObject>

答案 5 :(得分:0)
我在 iOS Safari 中发现了一个关于 foreignObject
的奇怪错误。当我在 CSS 中为 opacity
中的 HTML 内容设置 foreignObject
时(在我的例子中它是一个按钮),它会将它绝对定位在 SVG 上。但是当我删除 opacity
时它按预期定位。我花了几个小时来调试这个问题。
