在没有HTML的Rails中获取图像URL [英] Getting the image URL without the HTML in Rails

问题描述

在Rails中，有一种方法可以获取图像的URL(通过assets_host)并仅返回图像的URL?我想在Javascript中使用assets_host数据，但只需要在JS中插入URL，而不是整个image_tag.

In Rails is there a way to get the URL to the image (going through the assets_host) and just return the URL of the image? I want to use assets_host data in my Javascript, but I just need to insert the URL into the JS, not the whole image_tag.

提前谢谢！

推荐答案

image_path 将返回(您猜对了)图像的路径.与image_tag中使用的方法相同.

image_path will return (you guessed it) the path to the image. It's the same method used in image_tag.
