This doesn't contain a reproducible example so I can't tell for sure. At a glance: edit_url is reactive (it is a memo, so will react to changes in both novel_name and chapter_title), {format!(...)} is not reactive, so that could be one cause of the issue. Otherwise, not sure. If you can provide a reproducible example I'm happy to take a look.

这不包含可重复的示例，所以我无法确定。一目了然：是被动的（它是备忘录，所以会对两者的变化做出反应），不是被动的，所以这可能是问题的原因之一。否则，不确定。如果你能提供一个可重复的例子，我很乐意看一看。
edit_url``novel_name``chapter_title``{format!(...)}
Thank you. I already know what the problem is, okay
this is a reproducible example, Ineed to use closures like href={move || format!("view/{}/{}", param_a(), param_b())}
use leptos::*;
use leptos_meta::*;
use leptos_router::*;
#[component]
pub fn App() -> impl IntoView {
// Provides context that manages stylesheets, titles, meta tags, etc.
provide_meta_context();
view! {
// injects a stylesheet into the document <head>
// id=leptos means cargo-leptos will hot-reload this stylesheet
<Stylesheet id="leptos" href="/pkg/tests-tag-a.css"/>
// sets the document title
<Title text="Welcome to Leptos"/>
// content for this welcome page
<Router>
<main>
<Routes>
<Route path="" view=ChangePramsB/>
</Routes>
</main>
</Router>
}
}
/// Renders the home page of your application.
#[component]
pub fn PageOne(param_a: ReadSignal<String>, param_b: ReadSignal<String>) -> impl IntoView {
// Creates a reactive value to update the button
let url = create_memo(move |_| format!("view/{}/{}", param_a(), param_b()));
view! {
<a href={format!("view/{}/{}", param_a(), param_b())}> test1 </a>
<a href={url}> test2 </a>
}
}
#[component]
fn ChangePramsB() -> impl IntoView {
let (param_a, set_param_a) = create_signal(String::from("aa"));
let (param_b, set_param_b) = create_signal(String::from(""));
view! {
<button on:click={move |_| set_param_b("bbb".to_string())}> "change param b" </button>
<PageOne param_a=param_a param_b=param_b />
}
}
