Class Ext.Fx

Fade an element in (from transparent to opaque). The ending opacity can be specified using the endOpacity config option. Usage:

// default: fade in from opacity 0 to 100%
el.fadeIn();

// custom: fade in from opacity 0 to 75% over 2 seconds
el.fadeIn({ endOpacity: .75, duration: 2});

// common config options shown with default values
el.fadeIn({
    endOpacity: 1, //can be any value between 0 and 1 (e.g. .5)
    easing: 'easeOut',
    duration: .5
});

Fade an element out (from opaque to transparent). The ending opacity can be specified using the endOpacity config option. Note that IE may require useDisplay:true in order to redisplay correctly. Usage:

// default: fade out from the element's current opacity to 0
el.fadeOut();

// custom: fade out from the element's current opacity to 25% over 2 seconds
el.fadeOut({ endOpacity: .25, duration: 2});

// common config options shown with default values
el.fadeOut({
    endOpacity: 0, //can be any value between 0 and 1 (e.g. .5)
    easing: 'easeOut',
    duration: .5,
    remove: false,
    useDisplay: false
});

Shows a ripple of exploding, attenuating borders to draw attention to an Element. Usage:

// default: a single light blue ripple
el.frame();

// custom: 3 red ripples lasting 3 seconds total
el.frame("ff0000", 3, { duration: 3 });

// common config options shown with default values
el.frame("C3DAF9", 1, {
    duration: 1 //duration of each individual ripple.
    // Note: Easing is not configurable and will be ignored if included
});

Slides the element while fading it out of view. An anchor point can be optionally passed to set the ending point of the effect. Usage:

// default: slide the element downward while fading out
el.ghost();

// custom: slide the element out to the right with a 2-second duration
el.ghost('r', { duration: 2 });

// common config options shown with default values
el.ghost('b', {
    easing: 'easeOut',
    duration: .5,
    remove: false,
    useDisplay: false
});

Returns true if the element has any effects actively running or queued, else returns false.

Returns true if the element is currently blocking so that no other effect can be queued until this effect is finished, else returns false if blocking is not set. This is commonly used to ensure that an effect initiated by a user action runs to completion prior to the same effect being restarted (e.g., firing only one effect even if the user clicks several times).

Highlights the Element by setting a color (applies to the background-color by default, but can be changed using the "attr" config option) and then fading back to the original color. If no original color is available, you should provide the "endColor" config option which will be cleared after the animation. Usage:

// default: highlight background to yellow
el.highlight();

// custom: highlight foreground text to blue for 2 seconds
el.highlight("0000ff", { attr: 'color', duration: 2 });

// common config options shown with default values
el.highlight("ffff9c", {
    attr: "background-color", //can be any valid CSS property (attribute) that supports a color value
    endColor: (current color) or "ffffff",
    easing: 'easeIn',
    duration: 1
});

Creates a pause before any subsequent queued effects begin. If there are no effects queued after the pause it will have no effect. Usage:

el.pause(1);

Fades the element out while slowly expanding it in all directions. When the effect is completed, the element will be hidden (visibility = 'hidden') but block elements will still take up space in the document. The element must be removed from the DOM using the 'remove' config option if desired. Usage:

// default
el.puff();

// common config options shown with default values
el.puff({
    easing: 'easeOut',
    duration: .5,
    remove: false,
    useDisplay: false
});

Animates the transition of an element's dimensions from a starting height/width to an ending height/width. This method is a convenience implementation of shift. Usage:

// change height and width to 100x100 pixels
el.scale(100, 100);

// common config options shown with default values.  The height and width will default to
// the element's existing values if passed as null.
el.scale(
    [element's width],
    [element's height], {
        easing: 'easeOut',
        duration: .35
    }
);

Ensures that all effects queued after sequenceFx is called on the element are run in sequence. This is the opposite of syncFx.

Animates the transition of any combination of an element's dimensions, xy position and/or opacity. Any of these properties not specified in the config object will not be changed. This effect requires that at least one new dimension, position or opacity setting must be passed in on the config object in order for the function to have any effect. Usage:

// slide the element horizontally to x position 200 while changing the height and opacity
el.shift({ x: 200, height: 50, opacity: .8 });

// common config options shown with default values.
el.shift({
    width: [element's width],
    height: [element's height],
    x: [element's x position],
    y: [element's y position],
    opacity: [element's opacity],
    easing: 'easeOut',
    duration: .35
});

Slides the element into view. An anchor point can be optionally passed to set the point of origin for the slide effect. This function automatically handles wrapping the element with a fixed-size container if needed. See the Fx class overview for valid anchor point options. Usage:

// default: slide the element in from the top
el.slideIn();

// custom: slide the element in from the right with a 2-second duration
el.slideIn('r', { duration: 2 });

// common config options shown with default values
el.slideIn('t', {
    easing: 'easeOut',
    duration: .5
});

Slides the element out of view. An anchor point can be optionally passed to set the end point for the slide effect. When the effect is completed, the element will be hidden (visibility = 'hidden') but block elements will still take up space in the document. The element must be removed from the DOM using the 'remove' config option if desired. This function automatically handles wrapping the element with a fixed-size container if needed. See the Fx class overview for valid anchor point options. Usage:

// default: slide the element out to the top
el.slideOut();

// custom: slide the element out to the right with a 2-second duration
el.slideOut('r', { duration: 2 });

// common config options shown with default values
el.slideOut('t', {
    easing: 'easeOut',
    duration: .5,
    remove: false,
    useDisplay: false
});

Stops any running effects and clears the element's internal effects queue if it contains any additional effects that haven't started yet.

Blinks the element as if it was clicked and then collapses on its center (similar to switching off a television). When the effect is completed, the element will be hidden (visibility = 'hidden') but block elements will still take up space in the document. The element must be removed from the DOM using the 'remove' config option if desired. Usage:

// default
el.switchOff();

// all config options shown with default values
el.switchOff({
    easing: 'easeIn',
    duration: .3,
    remove: false,
    useDisplay: false
});

Ensures that all effects queued after syncFx is called on the element are run concurrently. This is the opposite of sequenceFx.
