获取脚本标记所在的DOM元素 [英] Get DOM element where script tag is

问题描述

我需要编写一个脚本，它将使用document.write来产生一些输出，但我需要知道它包含哪个元素，例如：

I need to write a script that will use document.write to produce some output, but I need to know what element it is contained, example:

<p>
    paragraph 1
    <script src="test.js" type="text/javascript"></script>
</p>

我需要获得对p标签的引用...

I need to get a reference to the p tag...

谢谢！

推荐答案

在运行脚本时，文档仅部分加载。因此，您的脚本元素将是文档中的最后一个节点：

At the time the script is run, the document is only partially loaded. So your script element would be the last node in the document:

var target = document.documentElement; // start at the root element
while (target.childNodes.length && target.lastChild.nodeType == 1) { // find last HTMLElement child node
    target = target.lastChild;
}
// target is now the script element
alert(target.parentNode); // this is p
