javascript如何使用style属性查找哪些元素包含背景图像

Question

I am trying to add script to a web page that is generated as part of a go-daddy web site.

The image is presented in a div as a background image that was set using the style attribute.

style="background-image: url("//img1.wsimg.com/isteam/ip/c77f0810-0ea1-4425-b963-0e5820c70a3f/5a18a70f-82dc-45b6-bfb8-8f8e7ff1c875.jpg/:/cr=t:0%25,l:0%25,w:100%25,h:100%25/rs=w:1400,h:400,cg:true,m/cr=w:1400,h:400,ax:c,ay:c");"

The id of the div container is generated automatically and changes between runs.

Is there anyway I can find the elements on the page that have a background image set in the HTML style attribute using plain javascript ?

Answer 1

Try this:

var elements = document.body.getElementsByTagName("*")

for (var i = 0 ; i < elements.length ; i++) {
 if (elements[i].style.backgroundImage) {
    // DO SOMETHING HERE
    alert(elements[i].id + " has background image")
 }
}
