在javascript函数中更改文档背景图像

Question

I want to change the html documents background image in a javascript function but I'm having some difficulty with it. This is what I have:

function changeBgImage(){

    document.background = "url('images/SecondBackground.png')";

}

But as I said, not working.. Any ideas?

Answer 1

采用

document.body.style.backgroundImage = "url('images/SecondBackground.png')";

Answer 2

function changeBGImage() {
  document.body.style.backgroundImage = "url(http://images.cheezburger.com/completestore/2010/7/9/fe8e91c5-c3f1-40cf-a034-983e8683ba73.jpg)";
};

That'll do it!

Answer 3

您很亲近，但也需要.body。

document.body.style.background = "url('images/SecondBackground.png')";

Answer 4

试试这个

              document.getElementById("id of body").setAttribute("style","background-url:'images/SecondBackground.png'")
