Embedding URLs in a CFTREE
|
|
|
|
The HREF attribute in the CFTREEITEM tag allows you to designate tree items as links. To use this feature in a CFTREE, you simply define the destination of the link in the HREF attribute of CFTREEITEM.
|
|
|
|
Example: Adding Web links
|
|
|
<CFFORM ACTION="submit.cfm">
<CFTREE NAME="oak"
HIGHLIGHTHREF="yes"
HEIGHT="100"
WIDTH="200"
HSPACE="100"
VSPACE="6"
HSCROLL="no"
VSCROLL="no"
BORDER="no"
DELIMITER="?">
<CFTREEITEM VALUE="Important Links">
<CFTREEITEM VALUE="Allaire Home"
PARENT="Important Links"
IMG="document"
HREF="http://www.allaire.com">
<CFTREEITEM VALUE="Allaire Forums"
PARENT="Important Links"
IMG="document"
HREF="http://forums.allaire.com">
</CFTREE>
</CFFORM>
The resulting tree control looks like this:

|
The APPENDKEY attribute in CFTREEITEM |
|
|
|
When a user selects a tree item and submits the form, the CFTREEITEMKEY variable is appended to the URL passed to the application page specified in the CFFORM ACTION attribute, in the form:
http://myserver.com?CFTREEITEMKEY=selected_value
You can disable this key by setting the APPENDKEY attribute in the CFTREE tag to No.
|
|
|
|
The TARGET attribute in CFTREEITEM |
|
|
|
Use the TARGET attribute in the CFTREEITEM tag to specify a target for the link you've specified in the HREF attribute. When populating a CFTREE with data from a CFQUERY, you can separate TARGET attribute values in a comma-separated list to correspond with each level of linked tree items in your CFTREE, as shown here:
TARGET="FRAME_BODY,_blank,_top"
