trap
virtual override Obj? trap(Str name, Obj?[]? args := null)
The trap
operator will behave slightly differently based on the namespace of the element.
For HTML elements, trap
works as a convenience for prop
and setProp
:
div := Elem("div") div->tabIndex = 0 // equivalent to div.setProp("tabIndex", 0)
For SVG elements (where ns
is `http://www.w3.org/2000/svg`
), trap
routes to attr
and setAttr
:
svg := Svg.line(0, 0, 10, 10) svg->x1 = 5 // equivalent to svg.setAttr("x1", "5") svg->y1 = 5 // equivalent to svg.setAttr("y1", "5") svg->x2 == "10" // equivalent to svg.attr("x2")
