Question

I have three urls I have split down to keywords. In JavaScript I want to see if two of these Urls match two given keywords. Both keywords have to match two of the url’s for the code to proceed but I can’t think of a short way to do it.

I have tried…

if (url1 || url2 || url3 === "keyword1" && "keyword2") {
....
}

And

if (url1 || url2 || url3 === "keyword1" && url1 || url2 || url3 == "keyword2") {
    ....
    }

This is as far as I got. The problem is, it returns a match for just one of the keywords instead of only returning a match for both . I have a feeling that not ruling out the first match is causing the second to match the same variable. I hope this makes sense!

Can anybody help me?

If you combine all url values into a single array you can use .indexOf() (the page includes a compatible version if a browser doesn’t support this relatively new method).

var urls = [url1, url2, url3];

if (urls.indexOf('keyword1') >= 0 && urls.indexOf('keyword2') >= 0) {
    // both keywords are in there somewhere
}
