Search Javascript function "ifcurrentURLcontains("foobar\") { ...... } ?

[pstein]

I am searching for a JavaScript function which  let me check if the URL of the current webpage (e.g. "https:\\www.mydomain.com\foobar\blah\") contains a certain pattern (e.g. "foobar\")?

If yes, further, following commands should be executed.

Otherwise the processing should continue after If statement.

Is there such a function?

You can get the URL from location.href and use indexOf() to search for a string inside the URL. If you need a more complex search, you can use regular expressions.

Ok, thank you.

However

if ((location.href).indexOf("foobar\") == -1) {
alert(" not found");
}

is not working

Whats wrong?

You have the wrong slashes in url.

And because you have that wrong slash before the quote,  that usually escapes the quote from being treated as javascript quote at the end to a quote within a string.
