jquery gets background image src path

         
For example, get the body background:

The jquery code is as follows:

   var back = $ ('body'). css ('backgroundimage');            
  back.substring (Start, end);     Intercept the string start  from the first few characters to intercept end  is the end of the first



Here is the code for my background image of my blog:

var back = $ (' body '). CSS (' backgroundimage ');

Back.substring (4,66)

The results obtained:

"Http://images.cnblogs.com/cnblogs_com/xinlinux/584094/o_bg.jpg"
