INUSE_ATTRIBUTE_ERR [unsigned short, value: 10]
An attempt was made to add an attribute that was
already in use elsewhere. This error could occur if you acquired
an attribute via the getAttributeNode(
)
method and tried to add the same object instance to
another element using the setAttributeNode( )
method. You would
first need to create a new Attr
object, probably using the cloneNode(
)
method.
