Trying to return part of a url through regex (jquery)

Question

I'm trying to return a part of the url as a string and add it elsewhere.

So I do something like this:

var somestring = $("#hello").attr("href").text().replace(/part\/(\d+)/g, "part-$1");

Only I don't think this is correct. What's the correct way to do return the "part-$1" as a string?

Thanks!

Here's the example:

If successful the output should be something like Fake Urlpart-333.

Thanks!

Answer 1

Try:

var somestring = $("#hello").attr("href").replace(/^.*\/part\/(\d+).*$/g, "part-$1");
$("#hello").append(somestring);

• You don't need to call text() because attr() returns a string.
• You forgot a closing quotation mark.
• Since $("#hello") returns a single element, there is no need for each().

Here's a hint:

document.write(document.location.protocol);
document.write(document.location.host);
document.write(document.location.pathname);
