I want to know how to make a function run when a specific key is pressed in JavaScript. For Example, when I press enter, it will run function that does:
alert("You pressed enter");
Do you use addEventListener or what? Thank you!

Yes - jsfiddle
document.addEventListener('keydown',function(e){
var key = e.keyCode || e.which; // some browsers using keyCode,some which
if(key == 13){
alert('you press enter on the page');
}
});

var key = e.keyCode || e.whichYou can indeed use addEventListener, but use (for example jQuery) to prevent errors on different browsers.
For a list of keyCodes: http://www.javascripter.net/faq/keycodes.htm
$(window).keydown(function(event) {
if (event.which === 13) {
alert("You pressed enter");
}
});

keyCode is not standardized by jQuery, event.which is...
addEventListenerwe use. Can we see your code so far?
