Accordion: option animated true causes JavaScript error

Reported by: rdworth Owned by: scottgonzalez
Priority: critical Milestone: 1.8
Component: ui.accordion Version: 1.7.1

Blocked by: Blocking:

The accordion option 'animated' is documented as supporting boolean data type. animated: false works, but animated: true does not.


animated: true enables animation with 'slide' (the documented default animation)


animated: true causes a JavaScript error when a header is clicked.

jQuery.easing[this.options.easing || (jQuery.easing.swing ? "swing" : "linear")] is not a function

Looking into the error

this.options.easing is equal to a Boolean value of ''true'' when jQuery.easing[] is looking for a value of ''linear'' or ''swing''.

Getting the exisiting code to run

If we change the example that rdworth posted to

    animated: "swing"


    animated: "linear"

it runs fine.

Possible Solution

If we still want to use a Boolean value the code around line 329-331 of ui.accordian.js [1.7.1] needs to be adjusted to something like this:

var animations = $.ui.accordion.animations,
duration = o.duration,
easing = (typeof o.animated === "boolean")?"linear":o.animated;

with this change animated can have the following values: "linear" || "swing" || true
