Create a hyperlink to test _ HTML/Xhtml _ target

The target attribute of the link determines where the link is opened. Its values are usually _ blank, _ self, _ parent, _ top, and custom: new window, current window, parent window, top-level window, and frame. When the framework of the name does not exist, the custom function is equivalent to _ blank. Today, we mainly test that when the target attribute of the framework with the specified name is in the link of different levels of pages determines where the link is opened, its value is usually as follows: _ blank, _ self, _ parent, _ top, and user-defined parameters are displayed as follows: new window, current window, parent window, top-level window, and frame. When the framework of the name does not exist, the custom function is equivalent to _ blank. Today, we will mainly test the framework in which the link is opened when the framework with the name is in different levels or in different levels?
I. Test
1. Test 1: the framework with the specified name is on different pages.
Index.htm:


Aaa.htm:

Links
Bbb.htm:

Test results:
When target = "frame1", open it in index. frame1. (For convenience, the frame location is in the format of "Page name. Framework name)
When target = "frame2", it is enabled in aaa. frame2;
When target = "frame3", it is enabled in bbb. frame3;
2. Test 2: frameworks with the same name exist in different levels of pages
Index.htm:


Aaa.htm:

Frame2 "> Links
Bbb.htm:

Test results:
When target = "frame2", it is enabled in aaa. frame2;
3. Test 3: frameworks with the same name exist in different levels of pages
Index.htm:


Aaa.htm:

Frame2 "> Links
Bbb.htm:

Test results:
When target = "frame2", it is enabled in aaa. frame2;
4. Test 4: frameworks with the same name exist in different levels of pages
Index.htm:


Aaa.htm:

Frame1 "> Links
Bbb.htm:

Test results:
When target = "frame1", it is enabled in bbb. frame1;
Ii. Conclusion
