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.
In jQuery to set a hidden field value, we use . val() method. The jQuery . val() method is used to get or set the values of form elements such as input, select, textarea.
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.
To pass the value you must included the hidden value value="hiddenValue" in the <input> statement like so:
<input type="hidden" id="thisField" name="inputName" value="hiddenValue">
Then you recuperate the hidden form value in the same way that you recuperate the value of visible input fields, by accessing the parameter of the request object. Here is an example:
This code goes on the page where you want to hide the value.
<form action="anotherPage.jsp" method="GET">
<input type="hidden" id="thisField" name="inputName" value="hiddenValue">
<input type="submit">
</form>
Then on the 'anotherPage.jsp' page you recuperate the value by calling the getParameter(String name) method of the implicit request object, as so:
<% String hidden = request.getParameter("inputName"); %>
The Hidden Value is <%=hidden %>
The output of the above script will be:
The Hidden Value is hiddenValue
