Get URL from background-image Property
提问by Ozzy
i am currently using this to get the url from the background-image property:
我目前正在使用它从 background-image 属性中获取 url：
var url = $(this).find('div').css('background-image');
url = url.substr(4, url.length - 5);
This works fine however in some browser (IE6-9), instead of it being:
然而，这在某些浏览器（IE6-9）中工作正常，而不是：
url(http://.com/)
its
它的
url("http://.com/)
Is there a failsafe way that will just get the url from this property? without having to do browser detection or some other stuff?
是否有一种故障安全方法可以从该属性中获取 url？无需进行浏览器检测或其他一些东西？

You could do:
你可以这样做：
url = url.replace(/^url\(["']?/, '').replace(/["']?\)$/, '');
This will remove url('and url("from the beginning of the string if it is present and ")resp. ')from the end.
如果它存在并且resp，这将从字符串的开头删除url('和。从最后。url("")')
