JS动画与CSS3动画-优快云博客

Js动画

show / hide

var div = $('#test-show-hide'); div.show('slow'); // 在0.6秒钟内逐渐显示
div.hide(3000); // 在3秒钟内逐渐消失

slideUp / slideDown

垂直下拉，提前

div.slideUp(3000); // 在3秒钟内逐渐向上消失
div.slideDown(3000); // 在3秒钟内逐渐向下消失

fadeIn / fadeOut

淡入/淡出

div.fadeOut('slow'); // 在0.6秒内淡出
div.animate({ //在3秒内过渡到该状态
    opacity: 0.25,
    width: '256px',
    height: '256px'
}, 3000, function () {
    console.log('动画已结束');
    // 恢复至初始状态:
    $(this).css('opacity', '1.0').css('width', '128px').css('height', '128px');
});

CSS3动画

补间动画

transition只能设定初始和结束时刻的两个状态,中间的过程通过自动计算去完成。

transition 有四个子属性：

transition-property,需要变化的属性：
transition-duration,在延续时间段，
transition-timing-function,变换的速率变化
transition-delay：变换延迟时间。

transition-property，可以指定为all，元素任何可过渡（transition）属性值变化时都将执行过渡（transition）效果。也可以指定为特一变化的属性。

例如可以设置不同的属性，包括旋转、扭曲、缩放、位移、矩阵、原点 transform-origin、过渡属性 transition-property、过渡所需时间 transition-duration、过渡函数 transition-timing-function、过渡延迟时间 transition-delay
