Hi everyone. I can't seem to get a 'ready' event listener working. The
timeline loads properly, but I never get the "ready!" alert box.
Here's the relevant code:
function draw_timeline(term, start, end) {
var url = "http://localhost:8080/?term="; + term + "&start=" + start
+ "&end=" + end;
var query = new google.visualization.Query(url);
query.send(callback_draw_timeline);
if ( $("#timeline").is(":hidden") ) { $("#timeline").show(); }
function callback_draw_timeline(response) {
if (response.isError()) {
alert("Error in query: " + response.getMessage());
return;
};
var data = response.getDataTable();
var timechart = new
google.visualization.AnnotatedTimeLine(document.getElementById('timeline'));
google.visualization.events.addListener(timechart, 'ready',
function() {
alert("ready!")
});
timechart.draw(data, {displayRangeSelector: false} );
};
};
