我如何引用加载当前正在执行的脚本的脚本标签? [英] How may I reference the script tag that loaded the currently-executing script?
问题描述
如何引用加载了当前正在运行的 javascript 的脚本元素?
How can I reference the script element that loaded the javascript that is currently running?
情况是这样的.我有一个主"脚本被加载到页面的高处，第一件事是在 HEAD 标签下.
Here's the situation. I have a "master" script being loaded high in the page, first thing under the HEAD tag.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script type="text/javascript" src="scripts.js"></script>
scripts.js"中有一个脚本需要能够按需加载其他脚本.普通方法对我来说不太适用，因为我需要在不引用 HEAD 标签的情况下添加新脚本，因为 HEAD 元素还没有完成渲染:
There is a script in "scripts.js" which needs to be able to do on-demand loading of other scripts. The normal method doesn't quite work for me because I need to add new scripts without referencing the HEAD tag, because the HEAD element hasn't finished rendering:
document.getElementsByTagName('head')[0].appendChild(v);
我想要做的是引用加载当前脚本的脚本元素，以便我可以将新的动态加载的脚本标签附加到它之后的 DOM 中.
What I want to do is reference the script element that loaded the current script so that I can then append my new dynamically loaded script tags into the DOM after it.
<script type="text/javascript" src="scripts.js"></script>
loaded by scripts.js--><script type="text/javascript" src="new_script1.js"></script>
loaded by scripts.js --><script type="text/javascript" src="new_script2.js"></script>
