更改 SVG 代码时，使用 <defs> 部分中的 <use> 克隆时，图标不可见

  • 772

图标有一个svg代码，需要横向复制一份。
我怎样才能做到这一点？现在，当您在屏幕上打开图标时，没有图标。
那些。我对通过svg标签的方法感兴趣，例如使用标签use xlink:href 

<svg xmlns="http://www.w3.org/2000/svg" 
    xmlns:xlink="http://www.w3.org/1999/xlink" width="120" height="24" viewBox="60 0 24 24" >
<style type="text/css">

</style>
<defs>
<path id="star" class="st0" d="M800,318.1C624.6,318.1,481.9,175.4,481.9,0h-30.4H348.5h-30.4c0,175.4-142.7,318.1-318.1,318.1v30.4

也如此处：

  1. 或多或少像这样

    从 M800 的第一个坐标来看，我假设图标在 viewBox 之外很远，我将它设置为 0 0 800 800，然后偏移了 100

    嗯，当然是删太多了，代码变短了

  2. Best Answer

    如果 svg 元素不可见，您必须首先将文件加载到矢量编辑器中，这将帮助您查看原因

    在此处输入图像描述

    现在很清楚为什么该元素不可见 - 它首先位于 SVG 文档之外，并且比它大得多，大小为 800 x 800 像素。

    要将这个元素添加到现有的 SVG 文档中，您需要减少它

    800 / 24 = 33,33 раза我们将它减少 34 倍，以便文档边缘的缩进最小。

    减少是用命令完成的transform="scale(0.029)"

    1 / 34 = 0.029

    可以使用x=45命令中的参数更改元素之间的距离<use>

    更新

    不用矢量编辑器也可以使用 JS 方法找出 SVG 对象的位置和大小getBBox()

    let bb = star.getBBox();
 console.log(bb.width);
 console.log(bb.height);


    let bb = star.getBBox();
 console.log(bb.width);
 console.log(bb.height);

  3. 从“PS original”下面的问题中回答第二个代码示例

    查看您的代码在矢量编辑器中的样子

    错误与问题的第一部分相同。您正在 svg 文档之外绘制形状（它是一个灰色框），而不是按照您想要的比例。

    因此，当您将 Shape 的 SVG 代码复制到文档的 SVG 代码中时，您将看不到该形状，因为它位于 SVG 文档之外并且比它大得多。

    直接在 svg 文档内绘制（图中的灰色矩形）会更正确。在这个矩形内

    然后在输出处，您将收到一个将立即显示的代码。

    在此处输入图像描述

    当然，我现在将进行操作以减小 svg 形状，它将落入 SVG 文档中。

    您的身材的大小800 х 800px，因此，与第一个答案一样，我们缩小了身材
