Gebruiksaanwijzing:
Quote:
$('#id');
$('.class');
$('button > span');
$('#id, .class, button > span');
$('.class');
$('button > span');
$('#id, .class, button > span');
En bij meerdere elementen krijg je een array terug.
Ik dacht ik deel dit zodat andere mensen dit kunnen gebruiken of te verbeteren.
Hoor graag jullie mening!

Mijn script is ook nog niet helemaal af want er is 1 functie die dus niet cross-browser is.
http://caniuse.com/#search=getElementsByClassName
IE8, hier moet ik nog even wat op verzinnen

Code (js)
1
$=(s,e)=>{return(e||document).querySelectorAll(s);};
Moet je browser wel ECMA6 ondersteunen overigens, anders:
Code (js)
1
$=function(s,e){return(e||document).querySelectorAll(s);};
mocht je het tweede argument nooit gebruiken kan t nog simpeler:
Code (js)
1
var $ = document.querySelectorAll.bind(document);
Vaak gebruik ik zelf:

// ... mijn code
})(
function (selector, elem) { return (elem || document).querySelector(selector); },
function (selector, elem) { return (elem || document).querySelectorAll(selector); }
);
// ... mijn code
})(
function (selector, elem) { return (elem || document).querySelector(selector); },
function (selector, elem) { return (elem || document).querySelectorAll(selector); }
);
