8.2.2.5 Forms and Fields
Form Basics
GSP supports many different tags for working with HTML forms and fields, the most basic of which is the form tag. This is a controller/action aware version of the regular HTML form tag. The url
attribute lets you specify which controller and action to map to:
In this case we create a form called myForm
that submits to the BookController’s `list
action. Beyond that all of the usual HTML attributes apply.
Form Fields
In addition to easy construction of forms, GSP supports custom tags for dealing with different types of fields, including:
-
textField - For input fields of type 'text'
-
passwordField - For input fields of type 'password'
-
checkBox - For input fields of type 'checkbox'
-
radio - For input fields of type 'radio'
-
hiddenField - For input fields of type 'hidden'
-
select - For dealing with HTML select boxes
Each of these allows GSP expressions for the value:
<g:textField name="myField" value="${myValue}" />
GSP also contains extended helper versions of the above tags such as radioGroup (for creating groups of radio tags), localeSelect, currencySelect and timeZoneSelect (for selecting locales, currencies and time zones respectively).
Multiple Submit Buttons
The age old problem of dealing with multiple submit buttons is also handled elegantly with Grails using the actionSubmit tag. It is just like a regular submit, but lets you specify an alternative action to submit to:
<g:actionSubmit value="Some update label" action="update" />
