Summary

Tag name: <tr:importScript>
UIComponent class: org.apache.myfaces.trinidad.component.core.CoreImportScript
Component type: org.apache.myfaces.trinidad.CoreImportScript
The importScript component supports importing the built-in scripts provided by Apache Trinidad. It can be used to ensure that a Javascript function is available before using it in a Javascript handler. Only the first reference to a script will result in its being imported.

Code Example(s)

Events

Type Phases Description
org.apache.myfaces.trinidad.event.AttributeChangeEventInvoke Application,
Apply Request Values
Event delivered to describe an attribute change. 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 event might include the width of a column that supported client-side resizing.

Attributes

Name Type Supports EL? Description
attributeChangeListenerjavax.el.MethodExpressionOnly EL 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.
bindingorg.apache.myfaces.trinidad.component.core.CoreImportScriptOnly EL 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.
idStringNo the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
  • Must not be a zero-length String.
  • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
  • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
namesString[]Yes a series of function names
renderedbooleanYes Default Value: true

whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
