< script>中的./和/之间有什么区别吗? src属性? [英] Is there any difference between ./ and / in <script> src attribute?
问题描述
给出以下项目结构:
/root
/static
script.js
page.html
这将"导入" script.js到HTML文件:
This will 'import' script.js, into the HTML file:
<html>
<head>
<script src="/static/script.js"></script>
</head>
<body>
...
</body>
</html>
这也将:
<html>
<head>
<script src="./static/script.js"></script>
</head>
<body>
...
</body>
</html>
我想知道:
- 一种方法优先于另一种方法吗?
- 在
/和./的<script>属性中，/和./的行为会有所不同吗?
- Is one way preferred over the other?
- Are there any cases, when
/and./, in shesrcattribute of<script>will behave differently?
推荐答案
现在，我对JavaScript的了解不是很高，但是我会让你知道我所知道的.
Now, I am not super experienced in JavaScript, but I'll let you know what I know.
[...]
<script src="./static/script.js"></script>
[...]
<!--This would reference files in the current folder (where the webpage itself is stored)-->
[...]
<script src="/static/script.js"></script>
[...]
<!--This would reference an absolute path within your webserver, and cannot change dynamically based on from where you load it.-->
通常来说，当您从当前文件夹(和/或服务器)中的文件加载./时，我会选择./，而/似乎是对我的外部引用，这也不是动态的.如果您碰巧移动了文件(如果文件与页面位于同一目录中)，我认为JavaScript也会引用新文件，而不是抱怨旧文件.
Generally speaking, I'd go for ./ when you load it from a file in your current folder (and/or server), whilst doing / seems like an external reference to me, which is also not dynamic. If you happen to move the file (if it was in the same directory as your page), I think JavaScript would also reference the new file instead of complaining about the old one.
我不能保证上面的任何信息都是正确的，因为我不是一个非常好的JS-Developer，但这至少应该可以帮助您进一步了解语法.
I cannot guarantee that any of the info above is correct as I am not a really good JS-Developer, but at least this should help you figure out the syntax a little more.
