Spring MVC hidden tag provides a way to render HTML hidden field.
The following tag
|
1 |
<form:hidden path="employeeId" value="12345" /> |
is rendered into HTML hidden field as
|
1 |
<input id="employeeId" name="employeeId" value="12345" type="hidden"/> |
Example : Spring MVC Hidden Tag
In this example we will declare a field “employeeId” as hidden in the form and display its value on submit.
