Creating a spoiler revealer

Hi. I've made a page with 3 articles. They each have buttons on them so that when the user clicks on 'read more', it reveals more of the article, like in the spoiler revealer exercise. I got it to work, but I have a question about it.

In my app.js file, my code is this

var $button = ("<button>Read More</button>");

$("span").hide();

$(".primary-content").append($button);
$(".secondary-content").append($button);
$(".extra-content").append($button);

$("button").click(function(){

  $(this).prev().show();
  $(this).remove();

});

what I don't understand is that, when I put

$("button").click(function()…

it works, but when I put

$button.click(function()…

it didn't work. I'm not sure why not. Could someone explain this to me? Thanks.

Hi Robin

Here is a jQuery click() Method:

$(selector).click(function)

So, I think the $button.click(function()… doesn't work because

$button = ("<button>Read More</button>") is not a selector, it's an html element

but `$("button") is a selector of button tags

Feel free to correct me if i'm wrong. Good luck

Thanks Sreng
