9. Trinidad Core Tag Reference

Documentation > Trinidad > Trinidad Tag Reference > Trinidad Core Tag Library > tr:inputHidden

tr:inputHidden

<p>The <tr:inputHidden> tag creates a value that will be submitted, but not rendered on the page.</p>

Example

<tr:inputHidden> </tr:inputHidden> 

HTML Output

<form id="_id2" name="_id2" method="POST" onkeypress="return _submitOnEnter(event,'_id2');" action="/TrinidadTestWeb/tags/jsf/inputHidden.jsf"><input type="hidden" id="_id2:_id3" name="_id2:_id3"><input type="hidden" name="org.apache.myfaces.trinidad.faces.FORM" value="_id2"><span id="__id2_Postscript"><input type="hidden" name="org.apache.myfaces.trinidad.faces.STATE" value="!9f84c53"><script>function __id2Validator(){return true;}var _id2_SF={};</script></span><script>_submitFormCheck();</script></form>

Tag Attributes

attributeChangeListener Text
 
a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding Expression
 
an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
converter Text
 
a converter object
id Text
 
the identifier for the component
immediate Text
 
whether the value is converted and validated immediately in the Apply Request Values phase, or is handled in the Process Validators phase, the default. By default, values are converted and validated together in the Process Validators phase. However, if you need access to the value of a component during Apply Request Values - for example, if you need to get the value from an actionListener on an immediate commandButton - then setting this to "immediate" makes that possible.
rendered Text
 
whether the component is rendered. When set to false, no output will be delivered for this component.
required Text
 
whether a non-null, non-empty value must be entered. If false, validators will not be executed when the value is null or empty.
requiredMessageDetail Text
 
The requiredMessageDetail attribute sets the custom error message with the parameters {0} for a label to identify the component when the value for the component is required (the required attribute is set to “true”) and validation fails.
validator Text
 
a method reference to a validator method
value Text
 
the value of the component. If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode.
valueChangeListener Text
 
a method reference to an value change listener
