Reduce the speed of a accordion in jquery UI

问题

I have two problems with this code:

First I would like to reduce the speed of the effect.

Second as you would for the effect to operate to close a tab and then there will be the following newly tab

if ($('#sidebar ul').length) {
    $("#sidebar ul").accordion({
        event: "mouseover",
        active: 1,
        collapsible: false,
        autoHeight: false
    });
}

回答1:

For the speed, use animate:

if ($('#sidebar ul').length) {
    $("#sidebar ul").accordion({
        event: "mouseover",
        active: 1,
        collapsible: false,
        autoHeight: false,
        animate: 2000 // miliseconds
    });
}​

From the jquery ui docs:

Animate

If and how to animate changing panels.

Multiple types supported:

• Boolean: A value of false will disable animations.
• Number: Duration in milliseconds with default easing.
• String: Name of easing to use with default duration.
• Object: Animation settings with easing and duration properties.
  • Can also contain a down property with any of the above options.
  • "Down" animations occur when the panel being activated has a lower index than the currently active panel.
