Data translators

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);

document.layers['timelayer'].document.timeForm.timefield.value = timeValue;

}

After you parse the orig attribute to populate the boxes in the Property inspector for the translated tag, the next

step is probably to set the value of the

orig attribute if the user changes the value in any of the text boxes. You might

find restrictions against making changes in a locked region. You can avoid this problem by changing the original

markup and retranslating.

The Property inspector for translated server-side includes (the ssi_translated.js file in the Configuration/Inspectors

folder) demonstrates this technique in its

setComment() function. Rather than rewriting the orig attribute, the

Property inspector assembles a new server-side include comment. It inserts that comment into the document,

replacing the old one by rewriting the contents of the document, which generates a new

orig attribute. The

following code summarizes this technique:

1 2 ... 335 336 337 338 339 340 341 342 343 344 345 ... 386 387
