I am using jquery bootpag to display pagination on a page

<div class="textgray showing"></div>

How should I tell jQuery to select this div? I tried the following without but neither of these attempts work

$(".textgray .showing").html("some text");

$(".textgray showing").html("some text");

P.S I am a beginner in frontend so bear with me

回答1:

The space means the second part is inside the first one (it's called the descendant combinator). Remove it:

$(".textgray.showing").html("some text");

回答2:

You don't need to put that extra space in between selector. space in selector looks for descendant elements:

$(".textgray.showing").html("some text");
