I want to have a div use a randomly chosen background image.
I am going to be adding to the possible background images over time.
Right now I have bg1.jpg and bg2.jpg. Eventually I might have dozens.
My first instinct is
var totalNum = 2;
var rndNum = Math.floor(Math.random() * totalNum);
$("div.target").css("background-image","url(/imagePath/bg" + rndNum + ".jpg)");
Then, every time I add a new image, I change totalNum to be accurate.
Is there an easier way? One that doesn't require me to keep changing the
script?
