Resetting body css background-image

Resetting body css background-image

If I try to reset the css-properties of the body of my page with this line of code:
  1. $("body").css({"background-image":"url('../images/bodyBack.jpg')","background-color":"#f5e7af","background-repeat":"repeat-x"});   
It sets the background-color correctly, but the background-image isn't set.

What do I do wrong?
