Ajax: Bind syntax

Binding Syntax

Most of the tags support a binding statement in the url or source attributes. The following syntax is supported.

Bind to a cfc

bind="cfc:component.dotted.path.cfcMethod({bindedElement})"

Url Binding

bind="url:url?name={bindedElement}&......."

JavaScript Binding

bind="javascript:jsFunction({bindedElement})"

The 3 bindings fashions are not supported by any tag. Check the single tag docs for specific support.

Parameters Syntax

The parameters passed to a binding statement can be declared following these rules:

On change of element with name myName the cfc is called passing myName=value as argument.

bind="cfc:ajaxproxy.cfc.test.getInfo({myName})

On change of elements with name 'myName' or element with name 'myAge' contained by an element with id 'myForm' cfc is called passing both fields as arguments.

bind="cfc:ajaxproxy.cfc.test.getInfo({myForm:myName},{myForm:myAge})

Events

Adding '@' after the element name allows to choose what event binding will listen to.

Possible events are :

* change ( default )
* mousedown
* keyup
* none

None will add the element to the querystring but will not trigger the binding if something happens to the element itself.

bind="cfc:ajaxproxy.cfc.test.getInfo({myName@none},{myAge@none},{btn@mousedown})
