javascript - How to set 'down' property to Jquery accordion animate? -

according jquery ui's formal api document, can set 'down' property animate.

multiple types supported:

• boolean: value of false disable animations.
• number: duration in milliseconds default easing.
• string: name of easing use default duration.
• object: object containing easing , duration properties configure animations.
  • can contain down property of above options.
  • "down" animations occur when panel being activated has lower index active panel.

if have codes this:

var accopts = {     easing: "linear",     duration: "fast", }  #("#accordion").accordion({     animate: accopts, }); 

how can set 'down' property?

you can use either boolean, number, string, or object, pass animate. add property accopts object. if set 1000, example, take 1 second when going backwards, instead of "fast" when going forward. i've shown example object, , thrown in variations comments.

var accopts = {    easing: "linear",    duration: "fast",    down: {      easing: "easeinoutquart",      duration: 1000    }        //down: false    //down: "easeinoutquart"    //down: 1000  }    $("#accordion").accordion({    animate: accopts,  });
