如何使用javascript在URL地址中找到字符串的一部分？

Question

Good evening, I have a problem to find string from url address when I click on next page, for example I have url: http://www.example.cz/example/example-example/page/2/ <- hyphen is optinal. I need to find part http://www.example.cz/example/example-example/ <- without part page/number/ and save it to variable. Can you guys help me how to do it ?

Answer 1

You could split on / and then reform the string.

For example (this assumes http:// is part of the string):

"http://www.example.cz/example/example-example/page/2/".split("/").slice(0,5).join("/")

1. Split on /
2. Slice out the first 5 items in the array.
3. Re-join them together with a /

Results: "http://www.example.cz/example/example-example"

Answer 2

If page is always in the url and also what needs to be removed, you can simply split on 'page' and take the first element of the resulting array.

var url = "http://www.example.cz/example/example-example/page/2/",
    urlParsed = url.split("page")[0];
