Usage of the target attribute of html tag a_HTML/Xhtml_Web page production

1: If you use the tag to link to a page, I believe everyone knows the role of the target attribute. It refers to how the linked page is displayed. Commonly used values ​​​​of target are: _blank (open a new browser window to open the linked page), _self (open the linked page in the original window). Of course, there are also _top and so on. Because they are not commonly used, I won’t introduce them here.
For example: Script Home means to link to Script Home and open it in a new window
2: If you use the tag to trigger an action (after the action is completed, you usually have to jump to a certain page). This action can be divided into two types here:
(1) Actions that do not submit the form (that is, actions that do not operate the form). Related scenarios in web development include: deleting a certain record individually, etc. Such operations are not very complicated and do not require many parameters. They are all submitted in the get method. At this time, you can specify the display form of the page to be jumped through the target attribute. The usage here is the same as that introduced in 1.
For example
Delete Xiao Ming means after processing the action , also opens a new page in this window.
(2) An action submitted in the form of a form (that is, an action to submit the data in the form). Such applications in web development are commonly related to user registration, information modification, etc. Of course, some people will say that the data in the submitted form can be submitted directly using or . But in some cases, you may prefer to submit in the form of . If you submit here in the form of tag , and you want to use the attribute target to control the page to be jumped after the processing is completed, it will not work. At this time, the target attribute no longer plays a role. Instead, you should specify it in the target attribute of the form, so that it will be as you wish!
For example:

Copy code

The code is as follows:

function check() { //Verify that it is not empty
if(form1.username.value=""){
return;
}
form1.submit();
}

Submit

means that after processing the action, return Open new page in new window. (Although the target attribute of the tag is set here, it will not work; instead, the target attribute of the form will work).
