Jquery 如何告诉浏览器重新呈现替换的SVG内容

我有一个SVG，到目前为止很简单；想象一下，我也想在我的页面上有一个SVG的缩略图

那么，实现这一目标的（相当简单的）方法是什么：

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

当

缩略图

和

图片

是SVG元素时

问题是，SVG引擎在内容更改后不会（重新）呈现。我确信我已经准备好阅读这里的解决方案了，但是我再也找不到了

注释一：如果服务器端的SVG的“html”是dup，它看起来就像我想要的一样漂亮

注释II:DOMbroser向我显示了正确的内容，但它没有显示在元素中

编辑

我想稍后将我的缩略图用作主svg的镜头

您可以将svg元素放入图像标记中，并根据需要设置图像标记的样式，从而调整其大小。不需要javascript

下面是一个jsfiddle来演示我将如何做到这一点

或者，如果您不想请求两次数据，可以执行以下操作：

jsfiddle:

js

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

var svg = $("#Layer_1");
var thumbnailWidth = svg.width() / 4;
var thumbnailHeight = svg.height() / 4;

 $("#Layer_1").clone().width(thumbnailWidth).height(thumbnailHeight).appendTo(".thumbnail");

.thumbnail{
    position:absolute;

    background:white;
    border: 1px solid grey;

为了清楚起见，您希望在主svg图像更改时重新渲染缩略图？否-无更改；我希望我的缩略图具有与主svg相同的内容（只是更小），并显示此内容，考虑一下，我不希望将svg数据发送两次以获得答案；这不符合我的问题。我想要两个svg，我不想两次传输数据这可能是一个解决方案，克隆一个div的内容并对其进行更改，而不是克隆svg（如果我正确阅读了您的答案），需要一点时间来实现这一点，我足够好，可以免费为您编写代码，其余的工作您可以完成。克隆svg interieur（内部）$（“#图片”）.clone（）.appendTo（$（“#lense svg”））
