原因:
By default, Safari Mobile does not use the :active state unless there is a touchstart event handler on the relevant element or on the <body>.
解决方法:
1.body标签上添加ontouchstart空方法(页面首个元素起作用)
<body ontouchstart="">
</body>
2.document或body添加touchstart空事件(页面首个元素起作用)
document.addEventListener("touchstart", function() {},false);
//或
document.body.addEventListener("touchstart", function() {})
/*添加如下css配合*/
html {
-webkit-tap-highlight-color: rgba(0,0,0,0);
}
3.单个a元素添加ontouchstart空事件
<a ontouchstart="">Click me</a>
4.所有a元素添加touchstart空事件
var a=document.getElementsByTagName(‘a’);
for(var i=0;i<a.length;i++){
a.addEventListener(‘touchstart’,function(){},false);
}
