Specifies that an element cannot be selected.
Syntax
HTML | <ELEMENT UNSELECTABLE=bUnselectable ... >
|
---|
Scripting | N/A |
---|
Possible Values
bUnselectable | Specifies whether an element is prohibited from being selected.
off | Default. Permits selection of the element. | on | Prohibits selection of the element. |
|
Remarks
Note Setting the
UNSELECTABLE attribute to
off does not ensure that the element is selectable. One example is an HTML Application (HTA) with the
SELECTION attribute set to
no. Elements in the body of the HTA cannot be selected, whether the element's
UNSELECTABLE attribute is set to
off or not.
Clicking on an element with the UNSELECTABLE attribute set to on does not destroy the current selection if one exists.
An element with the UNSELECTABLE attribute set to on can be included in a selection that starts somewhere outside the element.
The UNSELECTABLE attribute is implemented as an expando. Setting the expando property of the document object to false precludes the functionality of all expandos.
Example
This example shows that the UNSELECTABLE attribute is not inherited by child objects. Text in the TEXTAREA element can be selected and modified, but the text in the parent SPAN element cannot be selected.
<P>
<SPAN ID="oSpan" UNSELECTABLE="on" >This text cannot be selected.
<P>
<TEXTAREA WRAP="PHYSICAL" ROWS="5" STYLE="font-weight: bold;" ID="oTextarea">
This text can be selected and overwritten.
</TEXTAREA>
</P>
This text closes the SPAN and cannot be selected either.
</SPAN>
</P>
