这是可能的。请参阅通过src属性传递JavaScript参数。值得一提的是，由于HTML中的脚本（ not XHTML）是以加载的方式执行的，因此脚本可以找到它自己，因为它始终是触发时页面中的最后一个脚本 -

  var scripts = document.getElementsByTagName（'script'）; 
 var index = scripts.length  -  1; 
 var myScript = scripts [index]; 
 // myScript现在包含我们的脚本对象
 var queryString = myScript.src.replace（/ ^ [^ \？] + \ ?? /，''）; 
 

然后您只需应用查询字符串解析。

I am adding my Javsacript file in pages with different query strings in the script path like this:

Page1:

<script type="text/javascript" src="file.js?abc=123"></script>

Page2:

<script type="text/javascript" src="file.js?abc=456"></script>

Page3:

<script type="text/javascript" src="file.js?abc=789"></script>

In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work.

In case it helps, below is a function I use to find the value of a query string param:

function getQuerystring(key, defaultValue) {
    if (defaultValue == null) defaultValue = "";
    key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
    var regex = new RegExp("[\\?&]" + key + "=([^&#]*)");
    var qs = regex.exec(window.location.href);
    if (qs == null)
        return defaultValue;
    else
        return qs[1];
}

This is possible. See Passing JavaScript arguments via the src attribute. The punchline is that since scripts in HTML (not XHTML) are executed as loaded, this will allow a script to find itself as it is always the last script in the page when it’s triggered–

var scripts = document.getElementsByTagName('script');
var index = scripts.length - 1;
var myScript = scripts[index];
// myScript now contains our script object
var queryString = myScript.src.replace(/^[^\?]+\??/,'');

Then you just apply the query string parsing.
