ExtJS简单的动画效果2（ext js淡入淡出特效）

var WIDTH = 300; // 图片宽

var HEIGHT = 300; // 图片高

 

function reset() {

    // 以 Ext 获得指定元素，并指定此元素左边距、上方边距、右边距、下方边距

    Ext. get ( 'picture' ).highlight().setBounds(10, 10, WIDTH + 10, HEIGHT + 10);

}

 

function enlarge() {

    reset();

    // 在指定时间内移动到指定位置

    Ext. get ( 'picture' ).setBounds(150, 80, WIDTH + 50, WIDTH + 80, { // 指定的位置

       duration : 1.0 //duration:Number  事件完成时间（以秒为单位）

    });

}

 

function play() {

    Ext. get ( 'picture' ).highlight().fadeOut().fadeIn().pause(2).switchOff().puff();

    // IE 下不支持 switchOn() 方法，这是一个 Ext 的 bug

}

 

function fadeout() {

    // 设定最后不透明度为 0.0( 完全透明 ), 持续时间为 1.0 ，方式为 easeNone

    Ext. get ( 'picture' ).setOpacity (0.0, {

       duration : 1.0,

       easing : 'easeNone' //easing:String  行为方法 默认值是 :easeOut

    });

}

 

function fadein() {

    Ext. get ( 'picture' ).setOpacity (1.0, {

       duration : 1.0,

       easing : 'easeNone'

    });

}

 

function execution() {

    reset();

    var easingMethod = document.getElementByIdx_x( 'easing' ).value;

    Ext. get ( 'picture' ).setLocation(150, 150, {

       duration : 1.0,

       easing : easingMethod

    });

}

字段值

说明

easeNone

匀速

easeIn

开始慢且加速

easeOut

开始快且减速

easeBoth:

开始慢且减速

easeInStrong

开始慢且加速,t 的四次方

afterCls:String        事件完成后元素的样式
duration:Number        事件完成时间（以秒为单位）
remove:Boolean         事件完成后元素销毁?
useDisplay:Boolean      隐藏元素是否使用display 或visibility 属性?
afterStyle:String/Object/Function        事件完成后应用样式
block:Boolean           块状化
concurrent:Boolean      顺序还是同时执行
stopFx ：Boolean       当前效果完成后随合的效果是否将停止和移除

fadeOut( [Object options] ) : Ext.Element 渐隐 
fadeOut 和fadeIn 能使用一个特别的endOpacity 属性以指示结束时的透明度
例:el.fadeIn({duration:5,endOpacity:0.7});

frame( [String color], [Number count], [Object options] ) : Ext.Element 边框变亮扩展然后渐隐 
例:el.frame("ff0000", 10, { duration: 3 })

ghost( [String anchor], [Object options] ) : Ext.Element 渐渐滑出视图,anchor 定义 
tl     左上角( 默认)
t      上居中
tr     右上角
l      左边界的中央
c      居中
r      右边界的中央
bl     左下角
b      下居中
br     右下角
例:
el.ghost('b', {
    easing: 'easeOut',
    duration: .5
    remove: false,
    useDisplay: false
});

hasActiveFx() : Boolean 指示元素是否当前有特效正在活动 

hasFxBlock() : Boolean 是否有特效阻塞了 

highlight( [String color], [Object options] ) : Ext.Element 高亮显示当前元素 
例: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
});

pause( Number seconds ) : Ext.Element 暂停 

puff( [Object options] ) : Ext.Element 元素渐大并隐没 
例:el.puff({
    easing: 'easeOut',
    duration: .5,
    remove: false,
    useDisplay: false
});

scale( Number width, Number height, [Object options] ) : Ext.Element 缩放 
例:el.scale(
    [element's width],
    [element's height], {
    easing: 'easeOut',
    duration: .35
});

sequenceFx() 特效序列 

shift( Object options ) : Ext.Element 位移, 并可重置大小, 透明度等 
例:
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
});

slideIn( [String anchor], [Object options] ) : Ext.Element 淡入 

slideOut( [String anchor], [Object options] ) : Ext.Element 淡出 
例:el.slideIn('t', {
    easing: 'easeOut',
    duration: .5
});

stopFx() : Ext.Element 停止特效

switchOff( [Object options] ) : Ext.Element 收起并隐没 
例:
el.switchOff({
    easing: 'easeIn',
    duration: .3,
    remove: false,
    useDisplay: false
});
