Checks if the element has an attribute with the given name.
This function returns the same result as the following expression:
getAttr(attrName) != null
However, it will work faster, since no GOMAttribute
object will be allocated.
Parameters:
element
The element whose attribute is checked. If not specified, the
generator context element is assumed, i.e. the same as
the call: hasAttr(contextElement, attrName)
attrName
The attribute name
Returns:
true
if the element contains an attribute with the specified name;
false
otherwise (or in the caseelement == null
)
See Also:
getAttr(), setAttr(), hasAttrValue(), GOMAttribute
Tip:
You may call this function in a more method-like style, e.g.:
element.hasAttr(attrName)
