Kako dodati jQuery?

Napravi novi folder jQuery

Dodaj mu index.html file s osnovnom strukturom

Dodaj main.js file

Poveži main.js file s index.html

Dodaj ovo u head

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
</head>

Što je CDN?

Sintaksa

Basic syntax is: $(selector).action()

  • $ znakić koji znači da koristimo jQuery
  • Selektor koji ce odabrati elemente
  • Akcija koja performa nad selektanim elementom
$("p").hide() // hides all paragraphs

document.ready()

$(document).ready(function(){
  // jQuery methods go here...
});
// ili
$(function(){

  // jQuery methods go here...

});

This is to prevent any jQuery code from running before the document is finished loading (is ready)
