You can use below syntax in client script to hide a field. g_form. setVisible('fieldName', false);
Definition and Usage. The <input type="hidden"> defines a hidden input field. A hidden field lets web developers include data that cannot be seen or modified by users when a form is submitted. A hidden field often stores what database record that needs to be updated when the form is submitted.
Hidden form field is used to store session information of a client. In this method, we create a hidden form which passes the control to the servlet whose path is given in the form action area. Using this, the information of the user is stored and passed to the location where we want to send data.
var input = document.createElement("input"); input.setAttribute("type", "hidden"); input.setAttribute("name", "name_you_want"); input.setAttribute("value", "value_you_want"); //append to form element that you want . document.getElementById("chells").appendChild(input); If you love us?
