src是图像交换上的未定义变量

Question

Having problems with a (probably) simple task of passing a variable as a src of an image.

The variables are defined at random from an array, and then if URL criteria is met then that random variable is assigned as the src of the image.

jQuery:

var imgpathnamesfor7offers = ["offers1.jpg", "offers2.jpg", "offers3.jpg", "offers4.jpg"];
var randompathname = imgpathnamesfor7offers[Math.floor(Math.random() * imgpathnamesfor7offers.length)];
var produrl = jQuery(location).attr('href');
var icatRef = produrl.split("/")[4];
if (icatRef == "shark-steam-cleaning") {
    jQuery("#prodpagesliderbar-img").attr("src", jQuery("#prodpagesliderbar-img").attr("src").replace(randompathname));
}

Can anyone see what I'm doing wrong? Console appends 'undefined' to the end of the src.

Answer 1

instead of this:

jQuery("#prodpagesliderbar-img").attr("src").replace(randompathname)

this should be:

jQuery("#prodpagesliderbar-img").attr("src", randompathname)
