<method>

Attaches a function or event handler to an object or class.

Attaches a method to the object that contains this element. The method must have a name.

The name attribute allows the method to be invoked from JavaScript with this name. For example, if a method is defined via:

<view id="obj">
  <method name="f" args="a, b">
    return a+b;
  </method>
</view>

then script code can invoke obj.f(1, 2) to add two numbers.

Attributes
Name Usage Type (Tag) Type (JS) Default Category
args Tag only string   final
 

The parameter names of this method. The value of this attribute is a comma-separated list of JavaScript identifiers.


event Tag only string   final
 

The name of the event that this method is invoked in response to.


name Tag only token   final
 

The name of a variable that will be set to this object when the application is started. If this element is directly within a <canvas> or <library> element, the global variable and the canvas property with this name will be set to this object. If this element is within another object, that object's property with this name will be set to this object.


reference Tag only reference this final
 

If this attribute is present, it is a JavaScript expression that evaluates to an object. The code in this method executes when this object sends the event named by the event attribute. This attribute may be present only if the event attribute is present too.
