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. |
