Javascript是否与PHP中的__FILE__变量类似? [英] Is there any analogue in Javascript to the __FILE__ variable in PHP?

问题描述

非常简单，我有一个JS脚本，该脚本包含在许多不同的站点中，并且需要将参数传递给它.

Pretty straightforward, I've got a JS script that's included on many different sites and needs to have parameters passed to it.

如果可以通过URL传递这些信息，将非常有用，例如:

It would be useful if those could be passed via the URL, eg:

<script type="text/javascript" 
    src="http://path.to/script.js?var1=something&var2=somethingelse"></script>

是的，您仍然可以在单独的脚本标签中预填充变量，但这是一个杂乱无章的代码，传递起来不太容易:

Yes, you can still pre-populate variables, in a separate script tag, but it's a smidge messy and less easy to pass around:

<script type="text/javascript">var1=something; var2=somethingelse</script>
<script type="text/javascript" src="http://path.to/script.js"></script>

推荐答案

error.fileName 会告诉您脚本的来源文件(不确定它是否在每个浏览器中都有效；我已经在Firefox和Opera中对其进行了测试)

error.fileName will tell you the file that a script is from (not sure if it works in every browser; I've tested it in Firefox & Opera)

var filename = (new Error).fileName;
