440 Data Translators

Another problem is inherent in inspecting translated content. When you call the

dom.getSelection() function, the values that return by default are offsets into the

untranslated 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 offsets[0]+1 as the second argument ensures that you remain within the opening

lock tag when you convert the offsets to a node. If you use

offsets[1] as the second

argument, you risk selecting the node above the lock.

After you make the selection (after ensuring that its

nodeType is node.ELEMENT_NODE), you

can inspect the

type attribute to see if the locked region matches this Property inspector, as

shown in the following example:

if (theSelection.nodeType == node.ELEMENT_NODE && ¬

theSelection.getAttribute('type') == 'happy'){

return true;

}else{

return false

}

To populate the text boxes in the Property inspector for the translated tag, you must parse the

value of the

orig attribute. For example, if the untranslated code is <HAPPY TIME="22"> and

the Property inspector has a Time text box, you must extract the value of the

TIME attribute

from the

orig string:

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 lowercase for processing

var origAttLC = origAtt.toLowerCase();

var timeStart = origAttLC.indexOf('time="');

var timeEnd = origAttLC.indexOf('"',timeStart+6);

var timeValue = origAtt.substring(timeStart+6,timeEnd);
