src =" /images/logo.gif"有什么区别？和src =" images / logo.gif&quot ;? [英] What is the difference between src="/images/logo.gif" and src="images/logo.gif"?

问题描述

 
< img src =images / logo.gif/> 
 

相当于

但是

不同。

第三个项目在哪里寻找logo.gif

b
$ b

这是相对的，意思是：转到名为 images 的文件夹，然后获取资源 logo.gif

./ images / logo.gif 当前文件夹（点表示这个）转到名为 images 的文件夹，然后获取资源 logo.gif

<正如你所看到的，前两个意思是相同的，最后是最后一个。

这是绝对的，意味着：从Web服务器或文件系统的根目录或其他任何（斜杠意味着这一点）转到名为图像的文件夹，然后获取资源 logo.gif

<img src="images/logo.gif" />

is equivalent to

<img src="./images/logo.gif" />

But

<img src="/images/logo.gif" />

is different.

Where is the third item looking for logo.gif?

解决方案

images/logo.gif

It's relative and means: Go to a folder called images and then get the resource logo.gif

./images/logo.gif

It's relative and means: From the current folder (the dot means this) go to a folder called images and then get the resource logo.gif

As you can see the first two mean the same, finally the last one

/images/logo.gif

It's absolute and means: From the root of the web server or the file system or whatever (the slash means this) go to a folder called images and then get the resource logo.gif
