Invalid effect when passed to toggle method throws an exception only the first time its called
in Using jQuery UI
•
5 years ago
In code below, I am using toggle
method from jquery ui library to animate a div.
The first parameter is the name of
the effect like fold or drop or bouce.
When I pass an
invalid effect like `xyz` then the code below throws an exception
that gets caught by
the catch block.
However, on subsequent re-runs of
the same code no exception gets thrown
and also no animation happens since `xyz` is not a valid effect.
Question
:
Why the error for invalid effect is only being thrown when this code
runs the first time, but not on any runs after that?
I have a demo of this problem at
this jsfiddle url: http://jsfiddle.net/sun21170/rm580npe/7/
-
var emt = $("#cDiv"); try { emt.hide(); emt.toggle("xyz", { easing: "swing" }, 1000, function() { animationCompleted = true; startPolling(); }); } catch (e) { console.log(e.message); }
