javascript - How to properly stop Meteor Tracker.autorun? -

i have following:

meteor.startup(function() { var computation = tracker.autorun(function() { var currentchapter; currentchapter = chapters.findone({ _id: currentchapterid }); if (currentchapter) { if (currentchapter.title) { $("#input-title").val(currentchapter.title); } else { $("#input-title").val(""); } if (currentchapter.content) { $("#input-content").html(currentchapter.content); } else { $("#input-content").html(""); } } homecoming computation.stop(); }); });

right get:

exception tracker afterflush function: cannot phone call method 'stop' of undefined typeerror: cannot phone call method 'stop' of undefined

what want stop computation 1 time currentchapter true. doing wrong?

two things:

1 - autorun function gets handle computation passed it, can stop so:

meteor.startup(function() { var computation = tracker.autorun(function(thiscomp) { var currentchapter; currentchapter = chapters.findone({ _id: currentchapterid }); if (currentchapter) { if (currentchapter.title) { $("#input-title").val(currentchapter.title); } else { $("#input-title").val(""); } if (currentchapter.content) { $("#input-content").html(currentchapter.content); } else { $("#input-content").html(""); } thiscomp.stop(); } }); });

2 - in code, computation stopped @ end of first run regardless - should stopping within if (currentchapter) block.
