Just as further reference, and an up-to-date (may’14) (aug’15) (sep’16) (apr’17) (mar’18) (mar’19) (may’20) (jan’22)…
Answer that works with:
###Empty strings:
If theattr
must exist & could have any value (or none at all)
jQuery("[href]");
###Missing attributes:
Ifattr
could exist & if exist, must have some value
jQuery("[href!='']");
###Or both:
Ifattr
must exist & has to have some value…
jQuery("[href!=''][href]");
PS: more combinations are possible…
