I want to use Javascript to manipulate image files in Rails.

Assume you use the asset pipeline,

app/assets/images/1.jpg

If you placed an image file on the , you do not know how to specify the path when using Javascript.

For example, in a simple jQuery, in a js file (or script tag in an erb file),

$("button").click(function(){
  $("div").css("background-image", "url(1.png)");
});

But it doesn't work.

Could someone tell me?

The actual code is different, so I would appreciate it if you could tell me how to pass within js, not just in the css file.
