Introduction to the method attribute of the Form form in HTML

1 method is a property that specifies how data is sent to the server
2 It can only be post and get post: The official explanation is to transfer data to the server through the post session. It actually submits data. get: Add the data in the form to the URL pointed to by action in the form of variable=value, and connect the two with "?", and connect each variable with "&"; generally used to get data from the server.
3. The default is get, so we usually specify it as post

For example:

For example, there are two pages, a.htm and b.asp, and you want to pass the value in the form of page a.htm to page b.asp.
Then there will be the following form code in a.htm:

Copy code

The code is as follows:

There are two places to note in the above code:

1. The attribute of method is get, so the value is passed through the URL and is visible;
2. There are two objects in the form, a text box and a submit button. What needs to be passed is the value of the text box. Note that the id attribute of the text box must be changed to the name attribute, so that the value of the text box can be displayed at the URL.

When you browse to a.htm page and click the submit button, the page goes to b.asp page and the URL becomes:

http://localhost/WebSite2/b.asp?Text1=11

If you don't want the value to be displayed in the URL, just change the method value to post.

Then in b.asp, you can get the passed value through the server-side code.
When method=get, the b.asp page gets the value and outputs it through <% =Request.QueryString["Text1"]%>;
When method=post, the b.asp page obtains and outputs the value through <% =Request.Form["Text1"]%>.
