Syntax
@command( [EL-expression], [arbitraryKey]=[EL-expression] )
Description
Target Attribute: event attributes (e.g. onClick, onOK)
Purpose: Specify which command to execute when the event fires
You can pass arbitrary arguments in key-value pairs with comma separated.
- [arbitraryKey]=[EL-expression]
- It's key-value pairs basically. You can write multiple key-value pairs with different key names.
- An EL expression without key is set to a default key named "value" implicitly.
- Due to each annotation has different functions, some annotations may ignore key-value pair expression other than default key, e.g.@id.
- [arbitraryKey]
- It could be any name, it's used as a key for parameter related Java annotation in a ViewModel.
Example
<button label="Save" onClick="@command('saveOrder')" />
<button label="Delete" onClick="@command(empty vm.selected.id?'deleteOrder':'confirmDelete')" />
<button label="Index" onClick="@command('showIndex', index=10, keyword='myKeyword')"/>
