getElementsByClassName
can accept a whitespace-separated list of classNames (see MDN and spec).The current implementation prepends
.
to the className inquerySelectorAll
(i.e.,classOne classTwo classThree
->.classOne classTwo classThree
). This PR splits the className string by any amount of whitespace, then prepends a.
to each separated className, then joins to make a single query toquerySelectorAll
(e.g.,classOne classTwo classThree
->.classOne.classTwo.classThree
).Added test to confirm this new functionality.
