setStringValue method (CSSPrimitiveValue)

Browser support:
Specifies a string value for the CSSPrimitiveValue object with the specified type.
If the style property that belongs to the CSSPrimitiveValue object cannot accept the new value, the setStringValue method raises an exception. A CSSPrimitiveValue object can only be retrieved with the getPropertyCSSValue method.
Two objects exist in JavaScript that support the getPropertyCSSValue method, the style and CSSStyleDeclaration objects. The CSSStyleDeclaration object is read-only, so you cannot use the setStringValue method on it. The style object is writable in Firefox, but the getPropertyCSSValue method always returns null on it.
Therefore, the setStringValue method can only be used on the style object in Google Chrome and Safari.


object.setStringValue (type, value);
