href语法：可以在文件名中使用空格 [英] href syntax : is it okay to have space in file name

问题描述

一直以来我的做法是，当我使用图像时，我将它们命名为
walls_ico ， bu_hover



 < / p> 
 ; img src =images / walls_ico.ico/> 
< img src =buttons / bu_hover.png/> 
  

直到现在，当我在用户上传文件的项目时...

我想知道是否可以在文件和文件夹名称之间存在空格，如

 < img src =按钮/ bu hover.png/> 
  

解决方案

src 属性应该包含有效的网址。由于网址中空格字符不允许，因此您必须编码。

你可以写：

 < img src =buttons / bu％20hover.png/> 
  

但是不是：

 < img src =buttons / bu + hover.png/> 
  

由于DavidRR在他的评论中正确地指出，编码空间字符为 + 仅在URL的查询字符串部分有效，而不在路径本身中。

it has always been my practice that when ever i use images i name them like walls_ico , bu_hover

so when i give paths they go like

<img src="images/walls_ico.ico" />
<img src="buttons/bu_hover.png" />

UNTIL now when i am on a project where users upload files...

i was wondering is it okay to have spaces between file and folders name like

<img src="buttons/bu hover.png" />

解决方案

The src attribute should contain a valid URL. Since space characters are not allowed in URLs, you have to encode them.

You can write:

<img src="buttons/bu%20hover.png" />

But not:

<img src="buttons/bu+hover.png" />

Because, as DavidRR rightfully points out in his comment, encoding space characters as + is only valid in the query string portion of an URL, not in the path itself.
