xyph Posted July 24, 2012 Share Posted July 24, 2012 It doesn't have a href, and it doesn't need one According to the W3, it's optional. If you'd like to give it one, it wouldn't hurt anything It will change the behaviour when clicked though http://www.w3.org/TR/html4/struct/links.html#h-12.2 document.images is a collection of all the images on the current page http://www.webreference.com/js/column1/object.html Link to comment https://forums.phpfreaks.com/topic/266177-changing-images/#findComment-1364037 Share on other sites More sharing options...
200 Posted July 24, 2012 Author Share Posted July 24, 2012 Thanks for the reply and help. But what does if(document.images) do? Link to comment https://forums.phpfreaks.com/topic/266177-changing-images/#findComment-1364074 Share on other sites More sharing options...
xyph Posted July 24, 2012 Share Posted July 24, 2012 Checks if the object exists before using it. If the browser doesn't support it, it turns roll-overs off. I don't see the point of using the eye-roll emoticon. The question you asked is BASIC programming logic (not unique to JavaScript) Link to comment https://forums.phpfreaks.com/topic/266177-changing-images/#findComment-1364089 Share on other sites More sharing options...
