<switch> - SVG: Scalable Vector Graphics 编辑

The <switch> SVG element evaluates any requiredFeatures, requiredExtensions and systemLanguage attributes on its direct child elements in order, and then renders the first child where these attributes evaluate to true. Other direct children will be bypassed and therefore not rendered. If a child element is a container element, like <g>, then its subtree is also processed/rendered or bypassed/not rendered.

The display and visibility properties have no effect on <switch> element processing. In particular, setting display:none on a child has no effect on the true/false testing for <switch> processing.

SVG <switch> example

This example demonstrates showing different text content depending on the browser's language settings. The switch element will display the first of its child elements whose systemLanguage attribute matches the user's language, or the fallback element with no systemLanguage attribute if none of them match.
