svg - 未定义图像上 href 的 SVG 命名空间前缀 xlink

问题描述

我有一个看起来有点像这样的 svg 内容：

<svg height="1000" preserveaspectratio="xMidYMid meet" style="width: 100%; height: 100%; transform: translate3d(0px, 0px, 0px);" viewbox="0 0 1000 1000" width="1000"
    xmlns="http://www.w3.org/2000/svg">
    <defs>
        <clippath id="__lottie_element_2">
            <rect height="1000" width="1000" x="0" y="0"></rect>
        </clippath>
        <clippath id="__lottie_element_4">
            <path d="M0,0 L3048,0 L3048,2431 L0,2431z"></path>
        </clippath>
    </defs>
    <g clip-path="url(#__lottie_element_2)">
        <g clip-path="url(#__lottie_element_4)" opacity="1" style="display: block;" transform="matrix(0.5006899833679199,0,0,0.5006899833679199,-263.051513671875,-180.58868408203125)">

            </g>
            <g opacity="1" style="display: block;" transform="matrix(0.9999813437461853,0.006108480971306562,-0.006108480971306562,0.9999813437461853,504.42333984375,488.25836181640625)">
                <image height="1442px" preserveaspectratio="xMidYMid slice" width="2048px" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAACAAAAAWiCA...AAASUVORK5CYII="></image>
            </g>
        </g>
    </g>
</svg>

这是原始文件。

但是每当我尝试通过浏览器显示它时，我都会收到此错误：

This page contains the following errors:
error on line 1 at column 982067: Namespace prefix xlink for href on image is not defined
Below is a rendering of the page up to the first error.

我不知道为什么。请问怎么了？

标签： svgxlink

解决方案

该<svg>元素缺少xlink命名空间的声明，尽管它在<image>元素中使用。所以只需添加如下：

<svg height="1000" preserveaspectratio="xMidYMid meet" style="width: 100%; height: 100%; transform: translate3d(0px, 0px, 0px);" viewbox="0 0 1000 1000" width="1000"
    xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

SVG2 弃用了属性的xlink命名空间。href. 因此，在将来，更改xlink:href="..."为href="..."将是更好的解决方案。
