How do I set the down property for a jQuery animation?

According to the jQuery UI API format , we can set the down property for the animation.

Several types are supported:

  • Boolean: False will disable animation.
  • Number: Duration in milliseconds with default attenuation.
  • String: . The name to use with the default duration.
  • Object: An object containing the simplification and duration properties for customizing the animation.
    • May also contain a down property with any of the above options.
    • The Down animation occurs when the pane being activated has a lower index than the currently active pane.

If I have codes like this:

var accOpts = {
    easing: "linear",
    duration: "fast",
}

#("#accordion").accordion({
    animate: accOpts,
});

      

How can I set the property "down"?

You can use boolean, number, string, or object, just like you go to animate

. You just add it as a property to your object accOpts

. If you set it to 1000, for example, it will take more than one second to go backward, not "fast" when going forward. I gave an example with an object and threw in some options in the form of comments.



var accOpts = {
  easing: "linear",
  duration: "fast",
  down: {
    easing: "easeInOutQuart",
    duration: 1000
  }
  
  //down: false
  //down: "easeInOutQuart"
  //down: 1000
}

$("#accordion").accordion({
  animate: accOpts,
});
