Question

我有一个SVG，到目前为止这么容易;想象一下我也希望在我的页面上有一个这个SVG的缩略图。

所以，实现这一目标的方式很简单：

$('#thumbnail').html($('#the-picture').html())

w thumbnail和the-picture是SVG元素

问题是，SVG引擎在更改内容后没有（重新）渲染。我相信我已经在SO上阅读了解决方案，但我再也找不到了！

注释I：如果在服务器端复制svgs的'html'，它看起来就像我想要的那样漂亮

注释II：DOMbroser向我显示正确的内容，但它没有显示在元素

中

修改

我想将我的缩略图用作后来主svg的镜头

Answer 1

您可以通过将svg元素放入图像标记来调整其大小，并根据您的要求设置图像标记的样式。不需要javascript！

这是一个jsfiddle来演示如何做到这一点。 http://jsfiddle.net/A3v3c/1/

<强> HTML

<img class="thumbnail" src="http://s.cdpn.io/3/kiwi.svg">

<img class="main"  src="http://s.cdpn.io/3/kiwi.svg">

<强> CSS

.thumbnail{
    width:100px;
    position:absolute;
    top: 0;
    background:white;
    border: 1px solid grey;
}
.main{
    width:500px;
}

或者，如果您不想两次请求数据，您可以执行以下操作：
