Thanks for this basic suggestion. I've whipped something up that seems
promising. Currently I have one big issue, though: how can I get the cell
index for the js code that is executing?! This seems like it should be
simple, but I have been struggling lol. I can get the index of the selected
or focused cell, but that doesn't help much.
Here's a minimal example I'm working from:
%%javascript
var interval = 10;
// need replacement for THIS next line
// should return this cell's index
var idx = 0;
var cell = IPython.notebook.get_cell(idx);
element.append(idx + ' ')
var time = new Date();
element.append(time.getSeconds());
setTimeout(function(){
cell.execute();
}, interval * 1000);
any help much much appreciated. Once this works it seems straight forward
to put it in a magic.
