HTML JS Gets the value of all input in the table passed to the front end

1. Get the Table object

2. Loop, column loop, and then iterate through the input values in each lattice

3. Connect with a connector

4. Place inside the hidden field of the form.

5. Pass to the background.

JS Code: NOTE: 1.input must be followed by [0] Otherwise the value 2 cannot be removed. In the double quotation mark of JS cannot be changed to "" and {} in quotation marks will also be recognized error. Pass the string back to background processing
