Several common methods for passing additional parameters when submitting a form

When submitting a form, you may encounter situations where additional parameters are added before submission. There are several solutions to this problem:

1. Use hidden input in the form and put the parameters in it.

Disadvantages: Some input nodes will be added to the form, which feels uncomfortable.

2. Use javascript to dynamically add input to the form before submitting.

Disadvantages: Requires scripting.

3. Use ajax to submit the splicing parameters.

Disadvantages: This won’t work if there are files to upload in the form.
