The difference between html form submission action and url jump to actiond
|
The action of the form is different from the URL jump: The form can pass data to the background, and the background can directly use the request object to request data from the front end. There are two ways to pass data through a form: method="post": This is used to transfer large amounts of data. The data will be packaged before being transferred, so this method of transferring data will be less efficient, but the data that passes through can be parsed correctly, so there will be no garbled characters when transferring Chinese. method="get": transmitted via URL. Due to the limited length of the address bar, the amount of data is limited, and the transmitted data must be within the ASCII code value range. Therefore, garbled characters will appear when Chinese is transmitted, and special processing is required. The url jumps to the action only through the url parameters to pass data, action? parameter name = parameter value & ..., in the background, you can also use the request object to request the url parameter value from the front end (the url passing Chinese parameters needs special processing) |
