When using v-html in Vue, what is the difference between SVG rendering effect and writing templates directly, and how to solve it?

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:

  1. Check SVG code: Carefully check all attribute names in the SVG code, especially common attributes such as viewBox and fill .
  2. 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.
