try this..
$('#box1').click(function(){ $('.border #box1').css('background-color', 'red').css('color', 'red'); });
I believe you should give the function reference and not execute the function there:
document.getElementById("box1").addEventListener("click", click1); //-------------------------------------------------------------^
Do not "call" the function there.
You just need to add click event in HTML
and remove document.getElementById("box1").addEventListener("click", click1(1));
Answer by Suresh Ponnukalai for Change CSS color with Javascript on click (addEventListener)
If you want to pass arguments in addEventListener
, you have to modified your code like below.
document.getElementById("box1").addEventListener("click", function(){click1(1);}, false);
Answer by Werner for Change CSS color with Javascript on click (addEventListener)
As others already mentioned there is an issue in your second addEventListener
parameter.
You may look at this example:
var colorcheck = "#cccccc"; function click1() { document.getElementById(this.id).style.backgroundColor = '#ff0000'; colorcheck = document.getElementById("box1").style.backgroundColor; console.log(colorcheck); console.log(this.id); }; document.getElementById("box1").addEventListener("click", click1);
PS: look at the style attribute of box1. It's background-color
not backgroundColor
. The second one is only for JavaScript.
Answer by Rajesh for Change CSS color with Javascript on click (addEventListener)
As I have commented, document.getElementById("box1").addEventListener("click", click1(1))
was issue. Also instead of passing numbers click1(1)
, you can use this
.
You can try something like this:
Code
var colorcheck = "#cccccc"; function click1(blockid) { var self = this; self.style.backgroundColor = '#ff0000'; colorcheck = self.style.backgroundColor; console.log(colorcheck); console.log("box" + blockid); }; function registerEvents(){ var box = document.getElementsByClassName("box"); for(var i = 0; i
.box { width: 100px; height: 100px; background: black; margin:5px; }
