In HTML, different elements have attributes that contain link to the other resources. The values of these attributes are URL’s, these can be absolute or relative URL’s.
The <base> HTML element specifies the base URL to use for all relative URLs in a document. There can only be one single <base> element in a document, and it must be placed inside the <head> tag.
以下是HTML
必须在<base>标签中同时存在href属性和target属性，或者两者都有。
| S.No. | 的中文翻译为：S.No. | 属性和描述 |
|---|---|---|
| 1 | href 基本URL |
|
| 2 | 目标 在哪里打开目标URL − _blank - 目标URL将在新窗口或选项卡中打开。 _self - the target URL will open in the same frame as it was clicked. _parent - 目标URL将在父级框架中打开 _top - 目标URL将在顶部框架中打开，即窗口的完整主体。 |
<base herf= “base link…” target= “value”/>
以下是使用HTML中的<base>标签定义基本URL的示例 -
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="description" content="meta tag in the web document"> <meta name="keywords" content="HTML,CSS"> <meta name="author" content="lokesh"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- Declaring the BASE URL --> <base href="C:\Users\LOKESH BADAVATH\OneDrive\Desktop\TUTORIAL'S POINT\images\"target="_blank"/> </head> <body> <img src="https://img.zzsucai.com/202309/08/PqU5r541045104105.png" /> </body> </html>
使用
<!DOCTYPE html> <html> <head> <title>HTML base Tag</title> <base href = "http://www.tutorialspoint.com" /> </head> <body> HTML: <br><img src = "https://img.zzsucai.com/202309/08/7Y6Fc747489104127.gif" /> </body> </html>
