What is the difference between src and href? One article analysis!

src and href are commonly used attributes in HTML to refer to external resources or link to other documents. Although they look similar, there are some key differences in usage and functionality. This article will analyze the difference between src and href in detail and provide specific code examples.

src is an attribute used to specify the URL or path of embedded content. It is often used to reference external files, such as pictures, audio and video, scripts or frames, etc. The function of src is to embed external files into the current document for display or execution. For example, insert a picture in HTML, the code is as follows:

<img src="images/pic.jpg" alt="示例图片" />

In the above code, the src attribute specifies the path of the picture, the browser will obtain the picture through this path and display it in in the current HTML document. Similarly, we can also use the src attribute to introduce audio, video or script files.

In contrast, href is used to define the target URL of a hyperlink or the path to jump to other documents. The function of href is to create a hyperlink that allows users to jump to a specified URL or document after clicking it. The following is a simple hyperlink example:

<a href="https://www.example.com">点击跳转到示例网站</a>

After clicking the above link, the browser will jump to the "https://www.example.com" web page.

In addition to hyperlinks, href is also commonly used for the introduction of style sheet files. For example, we can introduce a CSS style sheet into an HTML document in the following way:

<link href="styles.css" rel="stylesheet" />

In the above code, the href attribute specifies the path to the style sheet file, and the browser will load the corresponding CSS style sheet based on this path. .

To summarize, src is used to embed content and display execution, such as pictures, audio and video or script files, etc. href is used to define hyperlinks or introduce external resources, such as jumping to a URL or loading a CSS style sheet.

It should be noted that due to different functions and usage scenarios of src and href, incorrect use of these two attributes may lead to unexpected results. For example, misusing src for hyperlinks or misusing href for inserting images, etc. So when using these two properties, make sure you understand their functionality and purpose and make the right choice as needed.

We hope that the analysis and code examples of this article can help readers better understand the difference between src and href, so that they can use these two attributes correctly in actual development.
