Click the button... and a calendar will pop up. after a date is selected on the calendar, the date will be displayed in the date text box.

I want to know how to get the content of the date text box and then pass the content to the B. php page, and the page does not jump. How can I obtain this value in B. php?

I am very grateful for the help of experts. any method can be used to achieve this. as long as the page is not redirected, please provide more details.

------ Solution --------------------
To minimize the modification, add the target and a hidden iframe in form. Yourframe is consistent.




------ Solution --------------------
Use ajax to request B. php.

Are you using jq or what?

You can add an id in input to obtain
$ ('# ID'). val ();

This is the case if no id is added.
$ ('Input [name = date] '). val ();


If the form is submitted directly, follow the steps on the # 1st floor.
If ajax is used, it is said on the second floor.
