indicates that the Property inspector is appropriate when the selection is within a locked region,
but because a document can have several locked regions, further checks must be performed to
determine if the Property inspector matches this particular locked region.
Another problem is inherent in inspecting translated content. When you call the
dom.getSelection()
source. To expand the selection properly so that the locked region (and only the locked region) is
selected, use the following technique:
var currentDOM = dw.getDocumentDOM();
var offsets = currentDOM.getSelection();
var theSelection = currentDOM.offsetsToNode(offsets[0],offsets[0]+1);
Using

tag when you convert the offsets to a node. If you use
risk selecting the node above the lock.
After you make the selection (after ensuring that its nodeType is

if (theSelection.nodeType == node.ELEMENT_NODE && ¬
theSelection.getAttribute('type') == 'happy'){
return true;
}else{

}
To populate the fields in the Property inspector for the translated tag, you must parse the value of
the attribute. For example, if the untranslated code is

function inspectSelection() {
var currentDOM = dw.getDocumentDOM();
var currSelection = currentDOM.getSelection();
var theObj = currentDOM.offsetsToNode¬
(curSelection[0],curSelection[0]+1);
if (theObj.nodeType != Node.ELEMENT_NODE) {
return;
}
// To convert the encoded characters back to their
// original values, use the unescape() method.
var origAtt = unescape(theObj.getAttribute("ORIG"));
// Convert the string to lower case for processing
var origAttLC = origAtt.toLowerCase();
var timeStart = origAttLC.indexOf('time="');
var timeEnd = origAttLC.indexOf('"',timeStart+6);
var timeValue = origAtt.substring(timeStart+6,timeEnd);
