How do I test if a HTML link element (a) containing a link href exists at DOM?

Question

I'm trying to check if a link already exists by it href property in a HTML document before to add another one.

The code is just like:

if (!$('a[href*="#businessInfoMenu"]')){
    //add new link   
}

Does anyone made something like that?

Thanks in advance,

You can check the length of the selector to see if there were any matches:

if ($('a[href*="#businessInfoMenu"]').length == 0) {
    //add new link
}
