After spending some time with Firebug to find and fix a couple of
typos, I've got it working now. There seems to be no way around
explicitly referring to the SPAN element (see below), but I can live
with that.
Now I need to tackle the next level, which is to expand the server-
side JSON function to return data for multiple sparklines on a page
and arrange to call sparkline() with the right data for each of the
corresponding elements.
Thanks again for the help!
Here's what's working correctly:
In the view ...
<script type="text/javascript">
/* <![CDATA[ */
$(function() {
$('.dynamicsparkline').everyTime(1000,function(i) {
var j = 2+i%5;
$.getJSON('{{=URL(r=request,f='call/json/
sparkdata')}}/'+j, function(data) {
var sparkdata = [10,9,8,7,6,5,4];
for(var k=0; k<sparkdata.length; k++) { sparkdata[k] =
data.a[k];}
console.log("sparkdata = " + sparkdata);
$('.dynamicsparkline').sparkline(sparkdata); // WORKS
// $(this).sparkline(sparkdata) // DOES NOT WORK!
});
});
});
/* ]]> */
</script>
<h1>This is the sparkline.html template</h1>
<p>
Sparkline with dynamic data: <span class="dynamicsparkline">Loading..</
span>
</
p>
and in the controller ...
@service.json
def sparkdata(j):
sys.stderr.write("\nsparkdata() called with j=%d\n"%int(j))
j = int(j)
return dict(a=[n%j for n in [10,9,8,7,6,5,4]])
Cheers,
Mike
