|
|
<p>In modern apps, and especially on the web, we often want to send our users to an
|
|
other website. <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.External"><code>External</code></a> allows us to make a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> navigate to an
|
|
external page.</p>
|
|
<blockquote>
|
|
<p>You might already now about
|
|
<a href="../failures/external.html">external navigation failures</a>. The <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a>
|
|
component doesn't rely on the code path where those originate. Therefore a
|
|
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> will never trigger an external navigation failure.</p>
|
|
</blockquote>
|
|
<p>Strictly speaking, a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> is not necessary for navigating to external
|
|
targets, since by definition the router cannot handle them internally. However,
|
|
the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> component is more convenient to use, as it automatically sets the
|
|
<code>rel</code> attribute for the link, when the target is external.</p>
