什么是最简单的< script>用参数标记 [英] What's the simplest <script> tag with params

问题描述

我想在提供参数的同时包括一个脚本标签.这是我到目前为止想出的结果

I want to include a script tag, while providing a parameter to it. This is what I came up with so far

1. 为脚本URL提供参数(cons:生成多个JS文件)

1. Provide a parameter to script URL (cons: generate multiple JS files)

<script src="http://example.com/something.js?P=123" type="text/javascript"></script>

隐藏脚本标记中的参数(与#1相同)

Hide parameter in script tag (cons: same as #1)

<script src="http://example.com/scripts/123/something.js" type="text/javascript"></script>

Google Analytics(分析)方式(缺点:丑陋，复杂的全局变量)

Google Analytics way (cons: ugly, complicated, global variables)

<script type="text/javascript" charset="utf-8">
  var _something = _something || 123;
  (function() {
    var s = document.createElement('script');
    s.type = 'text/javascript';
    s.src = 'http://example.com/something.js';
    var ss = document.getElementsByTagName('script')[0];
    ss.parentNode.insertBefore(s, ss);
  })();
</script>

推荐答案

如果脚本的执行方式取决于调用方式，则可以添加选项1之类的参数.

If the way the script is executed, depends on how it's called, you can add params like your option 1.

其他方式是:

<script params='{"abc": 123}' src="script.js"></script><!-- params is a non standard, non official attr that the script will read -->

或

<script>var _abc = 123;</script>
<script src="script.js"></script>

甚至

<script src="script.js#abc=123"></script>

尽管如此，我必须同意@outis的观点:始终为每个人加载相同的东西，然后像您/客户想要的那样执行它.

I have to agree with @outis though: load the same thing for everybody, always, and execute it like you/the client want(s) afterwards.
