Example The following example gets the current node, locates a table within it, and later calls dw.nodeExists() to see if the original node still exists: function applyFormatToSelectedTable(){ // get current selection var selObj = dw.getDocumentDOM().getSelectedNode(); alternateRows(dwscripts.findDOMObject("presetNames").selectedIndex, findTable()); // restore original selection, if it still exists; if not, just select the // table. var selArr; if (dw.nodeExists(selObj)) selArr = dom.nodeToOffsets(selObj); else selArr = dom.nodeToOffsets(findTable()); dom.setSelection(selArr[0],selArr[1]); } dreamweaver.nodeToOffsets() (deprecated) Availability Dreamweaver 2; deprecated in 3 in favor of "dom.nodeToOffsets()" on page 256.
