JavaScript jQuery Basics (2014) Creating a Spoiler Revealer Perform: Part 1

Why can't we append the button to the span?

Hey guys, One basic thing that I'm confused about is that why do we hide the span but append to the whole spoiler (<p>) element ? Why couldn't we either hide and append to the span element or hide and append to the whole spoiler(<p>) element?

So, do either

//1. Hide spoiler $(".spoiler").hide();

//2. Add a button $(".spoiler").append("<button>Reveal Spoiler</button>");


//1. Hide spoiler $(".spoiler span").hide();

//2. Add a button $(".spoiler span").append("<button>Reveal Spoiler</button>");

If you hide the whole spoiler span, then put the button inside it, wouldn't the button be hidden as well? Same for hiding the whole spoiler element. I think by hiding just the spoiler span, and placing the button outside the span, you're making sure the button displays but the spoiler text doesn't.

Hi Mayank,

I think the reason is because you aren't supposed to add other elements to a span, but I'm not entirely sure. You might want to use the solution below instead.

$(".spoiler span").text("Reveal Spoiler");
