How may I reference the script tag that loaded the currently-executing script? (14 answers)

Closed 9 years ago.

我需要撰写一份使用文件的文本。编写一些产出的书面材料,但我需要了解其中的内容,例如:

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

我需要参考正文......。

感谢!

Answer 1

当时,文件只部分装满。因此,你的文字内容是文件中的最后一点:

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

<p>
    paragraph 1
    <script id="test" type="text/javascript">
        var scpt = document.getElementById( "test" );
        var p = scpt.parentNode;
        p.removeChild( scpt );
        alert( "old content: " + p.innerHTML );
        p.innerHTML = "some new content";
    </script>
</p>

Answer 3

Why not just put an id on the relevant p tag?

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

Then, you can do a getElementById("desiredTag") or $("#desiredTag").
