What could be causing the background color not to change to green?
var id;
id = setInterval(changeColor, 1000);
function changeColor(){
var elem= $("#target");
var color = elem.css('background-color');
if (color == 'rgb(255,0,0)')
elem.css('background-color','green');
else
elem.css('background-color', 'red');
}
Give this a shot:
let timerId;
timerId = setInterval(alterBackground, 1000);
function alterBackground(){
let targetElement= $("#target");
let backgroundColor = targetElement.css('background-color');
if (backgroundColor == 'rgb(255, 0, 0)')
targetElement.css('background-color','green');
else
targetElement.css('background-color', 'red');
}
The if statement was checking the wrong condition: 'rgb(255,0,0)' instead of 'rgb(255, 0, 0)'
Consider using rgba instead of rgb for better color transparency.
