标签：function over event 原因 def not 文档 active detail
By default, Safari Mobile does not use the :active state unless there is a
touchstart event handler on the relevant element or on the
ontouchstart 空方法（页面首个元素起作用）<body ontouchstart=""></body>
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);
}
<a ontouchstart="">Click me</a>
var a=document.getElementsByTagName(‘a’);
for(var i=0;i<a.length;i++){
a[i].addEventListener(‘touchstart’,function(){},false);
}
