How to hide textbox with id ..?

hi all

can anyone tell me how to hide the text box by using the id .

on submitting form id should also store into the database.

im getting other table id into form but im unable to store .

Assign a expression ng-show or ng-hide to text box that initially results in true or false and then when you want to hide it just reverse the value.
On your second point To store the values to database you must be using AJAX call so just send additional parameter as id to request and store it in database
