问题描述

如何在.aspx页面上的HttpContext.Current.Request.Url.Host和HttpContext.Current.Request.Url.Authority之间使用样式-url标记的三元条件（要检查它是不是本地主机还是不直接） ？

How to use ternary condition with style - url tag, between HttpContext.Current.Request.Url.Host and HttpContext.Current.Request.Url.Authority on .aspx page to (want to check is it localhost or not directly)?

这里是示例：

"div style='<%= "height: 1115px; background-image: url(\"" + "http://" + HttpContext.Current.Request.Url.Host.ToString() +"ImagePath"); background-position: bottom center; background-repeat: no-repeat;" %>'"

我要检查是否

推荐答案

.aspx代码（抱歉，它很长，我无法将其分解成多个而不破坏语法）：

this .aspx code (sorry, it's long, I couldn't break it into multiple without breaking syntax):

<div style='<%= "height: 1115px; background-image: url(\"http://" + (HttpContext.Current.Request.Url.Host.ToString().Contains("localhost") ? HttpContext.Current.Request.Url.Authority : HttpContext.Current.Request.Url.Host ) + "/" + "path/to/image.jpg" + "\"); background-position: bottom center; background-repeat: no-repeat;" %>'>my_div_content</div>

会产生以下结果：

<div style="height: 1115px; background-image: url("http://lc.host.com/path/to/image.jpg"); background-position: bottom center; background-repeat: no-repeat;">my_div_content</div>

假定您的 ImagePath variabl包含真实的图片的路径，您需要在div中替换此行：

given that your ImagePath variabl contains the real path to your image, you need to replace this line in the div:

+ "path/to/image.jpg" + 

其中：

+ ImagePath + 

不要担心两个 style = 和 url（ 包含 ，无论如何应该可以。我确认了

Don't worry that both style=" and url(" contain ", it should work anyways. I confirmed this in Chrome.
