如何将用户从一个 url 重定向到另一个具有 JavaScript 操作（例如添加到购物车）的网站

Question

An example would be Website A has a product image that when you click on it, it redirects you to website B's cart page with the said product having already been added to the cart. Website B uses javascript to add to cart function. Right now I'm redirecting users to the product page which is really not good user experience.

Answer 1

If you want to redirect with JavaScript you could use window.location.href = "https://some url here"

What that url would be is up to the site you want to redirect them to.

Now, if website B uses URLs to add items to the cart, you would need to replicate such a url. If it does not, and you have access to site B, you could add a listener to intercept such redirects.

Otherwise, you may need to figure out some other mechanism, such as iframe and or proxy, it would depend on site B.

Answer 2

You can use window.location by passing the URL of website B
