This test checks the use of SVGAnimatedEnumeration within SVGComponentTransferFunctionElement On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Check initial 'type' value PASS feFuncRElement.type.toString() is "[object SVGAnimatedEnumeration]" PASS typeof(feFuncRElement.type.baseVal) is "number" PASS feFuncRElement.type.baseVal is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_IDENTITY Switch to 'table' PASS feFuncRElement.type.baseVal = SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_TABLE is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_TABLE PASS feFuncRElement.type.baseVal is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_TABLE PASS feFuncRElement.getAttribute('type') is "table" Switch to 'discrete' PASS feFuncRElement.type.baseVal = SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_DISCRETE is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_DISCRETE PASS feFuncRElement.type.baseVal is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_DISCRETE PASS feFuncRElement.getAttribute('type') is "discrete" Switch to 'linear' PASS feFuncRElement.type.baseVal = SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_LINEAR is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_LINEAR PASS feFuncRElement.type.baseVal is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_LINEAR PASS feFuncRElement.getAttribute('type') is "linear" Switch to 'gamma' PASS feFuncRElement.type.baseVal = SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_GAMMA is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_GAMMA PASS feFuncRElement.type.baseVal is SVGComponentTransferFunctionElement.SVG_FECOMPONENTTRANSFER_TYPE_GAMMA PASS feFuncRElement.getAttribute('type') is "gamma" Try setting invalid values PASS feFuncRElement.type.baseVal = 6 threw exception TypeError: Type error.
