Interface CSSPrimitiveValue

All Superinterfaces:

CSSValue

public interface CSSPrimitiveValue
extends CSSValue

The CSSPrimitiveValue interface represents a single CSS value . This interface may be used to determine the value of a specific style property currently set in a block or to set a specific style property explicitly within the block. An instance of this interface might be obtained from the getPropertyCSSValue method of the CSSStyleDeclaration interface. A CSSPrimitiveValue object only occurs in a context of a CSS property.

Conversions are allowed between absolute values (from millimeters to centimeters, from degrees to radians, and so on) but not between relative values. (For example, a pixel value cannot be converted to a centimeter value.) Percentage values can't be converted since they are relative to the parent value (or another property value). There is one exception for color percentage values: since a color percentage value is relative to the range 0-255, a color percentage value can be converted to a number; (see also the RGBColor interface).

See also the Document Object Model (DOM) Level 2 Style Specification.

Since:

1.4, DOM Level 2

void setFloatValue(short unitType,
 float floatValue)
            throws DOMException

A method to set the float value with a specified unit. If the property attached with this value can not accept the specified unit or the float value, the value will be unchanged and a DOMException will be raised.

Parameters:

unitType - A unit code as defined above. The unit code can only be a float unit type (i.e. CSS_NUMBER, CSS_PERCENTAGE, CSS_EMS, CSS_EXS, CSS_PX, CSS_CM, CSS_MM, CSS_IN, CSS_PT, CSS_PC, CSS_DEG, CSS_RAD, CSS_GRAD, CSS_MS, CSS_S, CSS_HZ, CSS_KHZ, CSS_DIMENSION).

floatValue - The new float value.

Throws:

DOMException - INVALID_ACCESS_ERR: Raised if the attached property doesn't support the float value or the unit type.
NO_MODIFICATION_ALLOWED_ERR: Raised if this property is readonly.

getFloatValue

float getFloatValue(short unitType)
             throws DOMException

This method is used to get a float value in a specified unit. If this CSS value doesn't contain a float value or can't be converted into the specified unit, a DOMException is raised.
