Question

I have access to a joomla edition but not the source, and I need add a link which must be opened in other window/tab.

I only can change the href field content.

I try with

javascript:window.open('http://url/')

this work with chrome but not with firefox.

any suggestion?

Answer 1

According to MDN, window.open() requires a minimum of two arguments. It also returns the object for the newly opened window, which would cause [object Window] to appear in the original window. Returning undefined avoids this second issue. This would work:

javascript:window.open('http://url/', '_blank');undefined

Older code would commonly use the void operator, which evaluates its only operand and yields an undefined result no matter what. So this would also work:

javascript:void(window.open('http://url/', '_blank'))

In either case, the special window name _blank just tells the browser to open a new window or tab. The browser’s settings determine the exact behavior because tabbed browsing was introduced after _blank was.
