Apr 04, 2025 pm 12:57 PM The difference and solution between using v-html
to render SVG in Vue and writing templates directly
In Vue.js projects, using the v-html
directive and writing SVG code directly in templates sometimes creates rendering differences, especially when dealing with SVG elements. This article will analyze its causes and provide solutions.
Problem: v-html
rendering SVG effect is abnormal
When writing a piece of HTML code containing SVG elements directly into the Vue template, the rendering effect is normal; however, the rendering effect is deviated by dynamically inserting the same code using the v-html
instruction.
Cause: SVG attribute case sensitive
HTML attribute names are case-sensitive, but SVG attribute names are case-sensitive. v-html
directive will strictly follow the SVG specification when parsing HTML, resulting in, for example, viewbox
is recognized as an invalid attribute, and viewBox
is the correct attribute name.
Solution: Fix SVG attribute case
The solution is simple: check whether there are case errors in the SVG code, such as changing viewbox
to viewBox
. When Vue processes v-html
content, it will strictly parse attributes according to the SVG specification, so it is necessary to ensure that the attribute name is case correctly.
Specific steps:
- Check SVG code: Carefully check all attribute names in the SVG code, especially common attributes such as
viewBox
andfill
. - Correct attribute name: Fix all case errors that do not comply with SVG specifications to correct case.
After ensuring that the SVG code complies with the SVG specification, the SVG effect rendered using v-html
will be consistent with the effect written directly in the template. This can effectively avoid inconsistent problems when rendering v-html
, and ensure the correct display of SVG elements in the application.
