我正在尝试为此代码添加过渡效果。它的作用是当你点击色板颜色时,产品会从原来的黑色变为另一种颜色。然而,转型并不容易,所以这是一个非常艰难的过渡。我在哪里添加过渡?
/* create fsm */
FsmTurnstile fsm = FSM_TURNSTILE_CREATE();
/* create fopts */
FsmTurnstileFopts fopts = {
.msg = ""
};
/* initialize input */
eFsmTurnstileInput input = EFSM_TURNSTILE_NOINPUT;
/* main loop */
for (;;) {
/* wait for timer signal, inputs, interrupts, whatever */
/* optionally set the input (my_input = EFSM_TURNSTILE_IN_PUSH for example) */
/* run state machine */
my_fsm.run(&my_fsm, &my_fopts, my_input);
}

实现所需效果的最简单方法是将两个图像div
放在一起。将较低的div
设置为目标图片,然后淡出顶部的div
。顶部div
淡出后,将其切换到目标图像并立即恢复其不透明度。由于您的帖子被标记为jquery
,我将在我的示例中使用其过渡函数(对于样本代码,请使用TinyGiant)。
function changeImage(url) {
$img = $('#imgDisp');
$imgfi = $('#imgDispFadeIn');
$imgfi.attr('src', url);
$img.fadeOut(1000, function() {
$img.attr('src', url)
$img.fadeIn(0);
});
}
span {
display: inline-block;
}
#imgContainer {
position: relative;
width: 100px;
height: 100px;
}
#imgDisp,
#imgDispFadeIn {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
#imgDisp {
z-index: 10;
}
.swatch {
width: 25px;
height: 25px;
}
.swatch.pink {
background: pink;
}
.swatch.black {
background: black;
}
.swatch.brown {
background: brown;
}
