使用JavaScript更改IE中的背景图片

Question

I am very new to JavaScript. Following line works for FF and Chrome, but not for IE 11:

var header = document.getElementsByTagName("header").item(0);       
header.style.backgroundImage = "url('./images/banner1.png'), url('./images/banner2.png')";

Any idea why not?

Thanks!

Answer 1

You simply need to change your logic to target the body element rather than the header element.

var header = document.getElementsByTagName("body").item(0);       
header.style.backgroundImage = "url('./images/banner1.png'), url('./images/banner2.png')";

PS You may want to change the name of the variable you create to something other than header, but I'll leave that up to you.

Hope this helps!
