The simplest way to handle this is to add a keydown handler to the
command (textbox) that prevents it from bubbling up to the document
keydown handler:
In the init() function, right after:
document.addEventListener("keydown", doKey, false);
Add this:
document.getElementById("command").addEventListener("keydown",
function(evt) {
evt.stopImmediatePropagation();
}, false);

Yes, I didn't spend the time to modify the example, but you can
certainly just push the single row to a javascript array
Something like:
var alldata=[]
function ev_command_enter_ajax(row)
alldata.push(row);
for(var i = 0; i < alldata.length; i++) {
ts = alldata[i]
//draw logic for a single row
}
Hope this helps
