Web Front-endJS TutorialHow to solve the problem of how to select the child elements of mouseover div in Jquery
There are many divs with the same class (assumed to be a), and each div has a span of the same class (assumed to be b). How can I select the span of the current div?
The method I found is
$(".a").mouseover(function(){$(".b",this).css(...)}) but it doesn’t work for me.

<span class="b">333</span>
<span class="b">444</span>
</div>
</body>
</body>
</html>Haha, it’s an own goal.
Didn’t you test my writing method? That's right, but I wrote the span outside the div.
That way of writing is indeed not common, I saw it on stackoverflow.
