jQuery将选择的png组合到一个图像时间轴动画中 [英] jQuery combine a selection of pngs to one image timeline animation

问题描述

由于文本上的白色边框以及其他像素化和抖动问题，GIF图像的动画制作很困难.因此，尽管没有在IE上对PNG的支持，但我还是做出了决定，尤其是fadeIn或fadeOut jQuery对PNG的影响导致黑边.

Animation is difficult with GIF images due to white borders on text and other pixelation and dithering issues. So I have decided despite the lack of support for PNG on IE especially fadeIn or fadeOut jQuery effects on PNG causing black borders to do it.

我有一个类似的文件夹

/cdn.com/ui/photo/1.png
/cdn.com/ui/photo/2.png
/cdn.com/ui/photo/3.png

这是我的HTML代码，是否有添加延迟或以某种方式循环并更改1-38的来源并保持循环的方式-甚至可以自定义延迟?我只希望它像完整的gif一样保持平稳的循环.

This is my HTML code, is there anway to add a delay or somehow loop and change the source of say 1-38 and keep looping it - maybe even customize the delay? I just want it to keep looping smoothly like a fully load gif..

<div class="m2m_badge">
    <a href="#"><img src="///cdn.com/ui/photo/1.png"/></a>
</div>

这是我的jQuery

This is my jQuery

$(function()
{
    var i = 0;
    var interval = setInterval(function()
    {
        $('div.m2m_badge a img').attr({ src: '//gc-cdn.com/ui/m2m/' + i + '.png' });
        i++;
        if(i === 38)
            clearInterval(interval);
    }, 250);
});

推荐答案

$(function()
{
    var i = 1;
    var interval = setInterval(function()
    {
        $('div.m2m_badge a img').attr({ src: 'http://www.gc-cdn.com/ui/m2m/' + i + '.png' }); 
        i++;
        if(i === 38)
            clearInterval(interval); //38 images has been shown, stop the interval
    }, 50); //50ms between each swap
});    

这是演示

要进行连续循环，只需在interval if

To have a continuous loop just add i=1; within the interval if

$(function()
{
    var i = 1;
    var interval = setInterval(function()
    {
        $('img').attr({ src: 'http://www.gc-cdn.com/ui/m2m/' + i + '.png' });
        i++;
        if(i === 38)
            i=1; // SOLUTION
    }, 250); 
});
