The ‘src’ attribute in a tag is the path to an external file or resource that you want to link to your HTML document.
標記中的'src'屬性是您要鏈接到HTML文檔的外部文件或資源的路徑。
For example, if you had your own custom JavaScript file named ‘script.js’ and wanted to add its functionality to your HTML page, you would add it like this:
例如，如果您有一個名為'script.js'的自定義JavaScript文件，并想將其功能添加到HTML頁面，則可以這樣添加：
<!DOCTYPE html> <html lang="en"><head><title>Script Src Attribute Example</title></head><body><script src="./script.js"></script></body> </html>This would point to a file named ‘script.js’ that is in the same directory as the .html file. You can also link to other directories by using ’..’ in the file path.
這將指向名為“ script.js”的文件，該文件與.html文件位于同一目錄中。 您也可以在文件路徑中使用“ ..”鏈接到其他目錄。
<script src="../public/js/script.js"></script>This jumps up one directory level then into a ‘public’ directory then to a ‘js’ directory and then to the ‘script.js’ file.
這將跳到一個目錄級別，然后跳到“ public”目錄，再跳到“ js”目錄，再跳到“ script.js”文件。
You can also use the ‘src’ attribute to link to external .js files hosted by a third party. This is used if you don’t want to download a local copy of the file. Just note that if the link changes or network access is down, then the external file you are linking to won’t work.
您還可以使用'src'屬性鏈接到第三方托管的外部.js文件。 如果您不想下載文件的本地副本，則使用它。 請注意，如果鏈接更改或網絡訪問斷開，則鏈接到的外部文件將無法工作。
This example links to a jQuery file.
本示例鏈接到jQuery文件。
