React router history.push 没有从根目录添加路径？

Question

I have a autocomplete input field in my react app, base on the user selection react-router will redirect to the product detail page.

My product detail page path is structured as below:

<Route extact path={'/:category/:id'} component={ProductDetailContainer}/>

In my autocomplete, I have an onChange function that will trigger the redirect.

const handleChange(event, value) => {
   history.push(`${value.category}/${value.id}`) 
}

While this works when the user is in base URL path '/' , it will fail if the user attempt to use the autocomplete field in ProductDetailContainer due to the path has been added on top of the current path again, it will then become a path like this '/:PrevCategory/:NewCategory/:id'

I tried to use replace but it seems to do the same thing. So is there a way to reset history to base url before push()?

#Edit 1 This is where the to autocomplete field and history are a push.

export default TitleBar;

Answer 1

You are missing the base / while pushing.. if you do not have base / , il will keep appending.

history.push(`/${value.category}/${value.id}`)
