var hasContainerTab = $("#tabs").find("a[href='#container'").length == 1;

I upgraded jquery to 1.12.4

Now that statement is failing saying 

unrecognized expression: a[href='#container'

I referred lot of blogs (  https://github.com/jquery/jquery/issues/2829 ) around this, but I could not find a fix.

Can any one tell me how to re-write the statement as per the new version?
