Under the TP framework, how does the controller obtain the value on the page?

Question

I passed a value (such as id) to the view page from other places. Now I want to get the id value on the view page from the controller method corresponding to the view page. How can I get it? ?

Answer 1

Do you mean that AJAX cannot be submitted? In this case, the js may be written incorrectly. You can post the code for everyone to refer to.

Answer 2

If you are getting the value from the corresponding controller in the view, then you should get it via get

Answer 3

Add a form hidden field to pass the value.

<input type="hidden" name="a" id="a" value="123">
