A label, relative address, absolute address, Anchor Point technology

a label (link label)

form :

<a href= "link Address" target= "window name to open link" > Content section </a>

link address : A URL is usually used to indicate the meaning (form) of a linked address. Link addresses can be divided into:

Absolute address: means the page can be "directly" through the address. can also be divided into:

Internet Absolute Address: form is: http://domain name/directory name 1/directory Name 2/filename

Apply to: Web site (page)

Local absolute address: The form is: file:///letter:/directory name 1/directory Name 2/filename

for local sites (pages)--normally used Web sites, rarely use local absolute paths.

Typically, the local absolute path is absolutely prohibited.

Relative Address: (You can think that each relative position is omitted./)

Explanation: Refers to a relative position that corresponds to the location (folder) of the page where the current a tag is located.

Several special relative path names:

./: Directly refers to the "current directory", that is, the directory location of this file, usually can be omitted

.. /: Represents the "Up level" directory of the current directory.

./Directory Name: Represents the specified next-level directory name in the current directory

The above can be further combined, common as follows:

./p0.html

./abc/p1.html

.. /p2.html

.. /def/p3.html

.. /.. /def/abc/p4.html

Abc/def/hij/p5.html in the Hij directory in the Def directory in the current directory of the ABC directory p5.html

Small summary: Usually in practical applications, in a site within each other with relative address, if linked to external sites, you must use the absolute path of the Internet.

Not in good hands.

to open a linked window name : Specifies which window to open when the page is opened. In quotation marks that follow the target

Several fixed-meaning window names:

_self: Represents the window itself where the current page is located

_blank: Represents a "new window", that is, anyway, always open a new window to display the linked page

_parent: The parent window, in fact, is the window of the current window--the window can be nested to form a hierarchical relationship

_top: The topmost window in a window that represents the topmost level of a nested relationship

You can also set the name of the window yourself: if the window already exists, it opens in the window, and if the window does not exist, a new window is created and named and the link opens.

Anchor Point Technology

An anchor point actually refers to a "location" on a Web page.

The implementation of the anchor point: Need to use at least 2 times a tag to match the completion. The basic form is as follows:

<a href= "#锚点名" > Content section </a> ()

......... This may be a lot of content area ....

<a name= "anchor roll" > Content part </a>, no underline part is equally valid 2

Integrated application of anchor points and Links:

<a href= "link address url# Anchor" > Content section </a>

The meaning is to link to the specified Web page and navigate to the location of the specified anchor point for the page.

Eg:<aname= "Top" ></a>

<a href= "#top" style= "position:fixed;right:50px; bottom:50px; " > Back to Top </a>

Click Position to ABC to position to text 1

<a href= "#abc" > Positioning to Abc</a>

<a name= "abc" > Text 1</a>
