What is anchor point in html

The anchor point in HTML is one of the hyperlinks on the web page, also called the named anchor point, which can accurately control the location where the visitor reaches after clicking the hyperlink. Anchors are when users set tags in a document. These tags are usually placed at a specific topic or at the top of the document, and then create links to these named anchors that can quickly take the viewer to the specified location.

Anchor point--is a type of hyperlink on a web page, also called a named anchor point, located by name. A named anchor is a hyperlink within a page, like a quick locator, and is widely used.

Named anchors: Users set tags in the document. These tags are usually placed at a specific topic or at the top of the document. Then create these named anchor links that can quickly take viewers to the specified location

Benefits of creating anchor links:

Anchor links allow you Ability to precisely control where visitors arrive after clicking a hyperlink. Links without named anchors will take visitors to the top of the target page. When the article on the page is very long, it is troublesome to just move the scroll bar up and down to find the required part. In this case, you can create a hyperlink within the page to quickly find the required information.

How to create a named anchor:

The process of creating a link to a named anchor is divided into two steps. First, create a named anchor, and then create a link to the named anchor.

Define the following anchor points at appropriate locations in the HTML page:

<a name="top">这里是TOP部分</a> 
<a name="content">这里是CONTENT部分</a> 
<a name="foot">这里是FOOT部分</a>

(You can use the id attribute instead of the name attribute. Named anchors are also valid.)

There are two methods for accessing the above anchor points

One is to use the hyperlink tag <a></a> to create an anchor link, which is mainly used for anchor access within the page

<a href="#top">点击我链接到TOP</a> 
<a href="#content">点击我链接到CONTENT</a> 
<a href="#foot">点击我链接到FOOT</a>

Another way is to add an anchor mark directly after the page address, which is mainly used for anchor access between different pages

If the address of this page is http://file path/index .html, to access the foot anchor, just access the following link

http://文件路径/index.html#foot

html What exactly does the anchor do?

To put it simply, for example, if you want to read a very long article accurately by segment, you can use anchor points.

Code:

<a href="#001">跳到001</a> 
...文字省略 
<a name="001" id="001" ></a> 
...文字省略

In fact, the anchor point only needs the name. The id is added to make it more compatible.

The value of href should be the same as name / i d are consistent, and "#" must be added in front. The above code is compatible in ie6/7, ff, but not in ie8.

Because the <a></a> value of our anchor point is empty, we can just add a space so as not to affect the appearance.

The following code can be compatible with ie8

<a href="#001">跳到001</a> 
...文字省略 
<a name="001" id="001" > & n b s p </a> 
...文字省略

Another question, do you want to display the anchor content of a certain page (such as: 123.html)?

The code is as follows

<a href="123.html#001">跳到001</a> 
...文字省略 
<a name="001" id="001" > & n b s p </a> 
...文字省略

This is yesterday when I was working on the background. I wanted to implement "modify positioning", so I moved the anchor mark out (usually it is forgotten by me).

But the program said that to get the value, there must be "?" or "&" in the connection, so my anchor point is incompatible...

Haha! There will be a solution in the future!

Although there is a problem with anchor point compatibility in jsp pages, there is no problem in static pages, and it is still worth learning!

In WEB development, page anchors will be used.

HTML page anchor is used to link to a certain section of a page. W3School says that creating anchors uses the <a> (anchor) tag and the name attribute, but this is not the only way to create page anchors. Let’s briefly talk about two ways to make HTML page anchors.

We can use W3School’s online testing tool for testing. The test code after opening the link uses <a href=”#C4″> and <a name=”C4″>, and there is no problem in the test. Then change "<h2> <a name="C4″>Chapter 4 </a> </h2>" to "<h2 id="C4″>Chapter 4 </h2> "After testing, the effect is the same.

Note that in addition to using the name attribute of the anchor tag when making a page anchor, you can also use the id attribute. The value of the href attribute in the anchor <a> tag is # starting with the value of the target's name or id:

<html> 
<body> 
<p> 
<a href="#method1">页面锚点方法一</a> 
</p> 
<p> 
<a href="#method2">页面锚点方法二</a> 
</p> 
<h2><a name="method1">方法一</a></h2> 
<p>使用锚标签的 href 和 name 属性</p> 
<h2 id="method2">方法二</h2> 
<p>使用锚标签和 id 属性</p> 
</body> 
</html>
