需求:点击按钮希望像在PC端那样有个类似于hover的效果,触摸按钮变色,手指离开变回原来的颜色;


方法一:CSS3+JS
用keyframes动画,js点击按钮时添加keyframes动画,定时器移除keyframes动画

<style>
.btn{
font-size: 1.5em;
line-height: 2em;
text-align: center;
background: #ce4f54;
color: #fff;
width: 200px;
}
.bounce {
-webkit-animation-name: bounce;
animation-name: bounce;
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both
-webkit-transform-origin: center bottom;
-ms-transform-origin: center bottom;
transform-origin: center bottom
}
#jq22{
animate-duration: 2s;/*//动画持续时间*/
animate-delay: 1s;/*//动画延迟时间*/
animate-iteration-count: 1;/*//动画执行次数*/
}
@-webkit-keyframes bounce {
0%{background: #ce4f54;}
50%{background: #ff0;}
100%{background: #ce4f54;}
}@keyframes bounce {
0%{background: #ce4f54;}
50%{background: #ff0;}
100%{background: #ce4f54;}
}
</style>
</head>
<body><div>按钮按钮</div><script src="http://dn.yunzhenshi.com/js/jquery-1.8.3.min.js"></script>
<script>
$(function () {
$('#jq22').click(function () {
$('#jq22').addClass('bounce');
setTimeout(function(){
$('#jq22').removeClass('bounce');
}, 1000);
});
});
</script>
</body>
</html>
方法二:JS
用touchstart,touchend来进行样式的添加和移除。

<link rel="stylesheet" type="text/css" href="http://dn.yunzhenshi.com/css/reset-min.css">
<style>
.btn1{
font-size: 1.5em;
line-height: 2em;
text-align: center;
background: #ce39bd;
color: #fff;
width: 200px;
}
.btn2{
font-size: 1.5em;
line-height: 2em;
text-align: center;
background: #f00;
color: #fff;
width: 200px;
}
</style>
</head>
<body><div>按钮按钮</div><script src="http://dn.yunzhenshi.com/js/jquery-1.8.3.min.js"></script>
<script>
$(function () {
function changeColor(id,class1,class2) {
$("#"+id).on("touchstart",function () {
$(this).attr("class",class1)
})
$("#"+id).on("touchend",function () {
$(this).attr("class",class2)
})
}
changeColor("jq22","btn2","btn1")
});
</script>
</body>
</html>
方法三:JS
网友的力量是强大,后来从网上找到了一个列表页的demo,升级版。

.items li {

<script>
$(function () {
//自定义tap
$(document).on("touchstart", function (e) {
if (!$(e.target).hasClass("disable")) $(e.target).data("isMoved", 0);
});
$(document).on("touchmove", function (e) {
if (!$(e.target).hasClass("disable")) $(e.target).data("isMoved", 1);
});
$(document).on("touchend", function (e) {
if (!$(e.target).hasClass("disable") && $(e.target).data("isMoved") == 0) $(e.target).trigger("tap");
});//按钮点击效果
$(document).on("touchstart", ".action-btn:not(.disable)", function (e) {
var $this = $(this);
var flag = true;
//遍历子类
$this.find("*").each(function () {
//查看有没有子类触发过active动作
if ($(this).hasClass("active")) flag = false;
});
//如果子类已经触发了active动作,父类则取消active触发操作
if (flag) $this.addClass("active");});
$(document).on("touchmove", ".action-btn:not(.disable)", function (e) {
if ($(this).hasClass("active")) $(this).removeClass("active");
});
$(document).on("touchend", ".action-btn:not(.disable)", function (e) {
if ($(this).hasClass("active")) $(this).removeClass("active");
});});
</script>
</body>
