Hi there, I don't understand the brackets in the "show spoiler" button:
$("button").click(function(){ $(".spoiler span").show(); });
I don't get, why I have to end the functions rule inside the "{}" brackets with this one ")".
Thank's for your help in advance.
Best,
Sven

$("button").click(function(){ $(".spoiler span").show(); });
If you look at the function keyword, it's an event handler that's bounded itself to a button element, so it's going to perform something on that element.
If you look at how the keyword is structured (function() there's a second opening bracket there that needs to be closed at the end of the function block.
That's why it's closed like this });
Good luck!

Courses Plus Student 4,355 PointsHi Jonathan,
many thanks for your answer. I just typed, what I thought is more logical – but than it becomes clear. Just for clarification: "The key function keyword is an event handler, that's bounded itself to a button element" – that is, why the function looks, how it looks. Otherwise, it would be kind of that:
… .click(function) { $(".spoiler span").show(); }
Best,
Sven

$("button").click( //<-- We're saying we want something to happen when the button is clicked. 'Click' parentheses open here.
// Everything that happens here is what we want to happen when the button is clicked. We use an anonymous function to do this.
function(){ //<-- Anonymous function curly braces open here.
$(".spoiler span").show();
} //<-- Anonymous function curly braces close here.
); //<-- 'Click' parentheses close here.
Condensed, it looks like this:
$("button").click(function(){
$(".spoiler span").show();
});
