Howto loop through table cells in a selection
Hello,
I'm new to DW development, so I wonder if someone could help me. Say my user
selects a few cells in a column in a table, and then runs my command. How can
I loop through the cells in the selection, so that I can read and write the
text in each cell?
I realise this is probably trivial if you know your way around the object
model, but I don't, as yet.
Many thanks,
Roger Pearse

var dom = dw.getDocumentDOM()
// grab multiple selections, which corespond to pair's of offsets
var sel = dom.getSelection(true);
var objs = new Array();
for(var i=0;i<sel.length;i+=2){
// take current selection pair and convert to a tag
// and stuff into an array to play with
objs.push(dom.offsetsToNode(sel[i],sel[i+1]));
}
// set inertHTML of first node
objs[0].innerHTML='hello'
