输入中来自ajax jquery json调用的值隐藏

Question

I get data.my_id from an AJAX call. I want to place it inside a hidden input named my_id , but I am not able to do it. Is there a special way to succeed with this sort of input? Is it normal not to see the AJAX return in the sources of the page? Thanks and sorry for my school English.

// dat.my_id is working in an alert
$(#my_id).html(data.my_id);

<input type="hidden" name="my_id" id="my_id" value="<?= $my_id; ?>" />

Answer 1

You need to keep value of hidden empty initially.

<input type="hidden" name="my_id" id="my_id" value="" />

Then on ajax response you can set the value as below:

$("#my_id").val(data.my_id);

Answer 2

To pass a value to your input you can use

$('#my_id').val(data.my_id);
