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>.
解決方法:
1.body標籤上新增ontouchstart空方法(頁面首個元素起作用)
<body ontouchstart=""> </body>
2.document或body新增touchstart空事件(頁面首個元素起作用)
document.addEventListener("touchstart", function() {},false); //或 document.body.addEventListener("touchstart", function() {})
/*新增如下css配合*/ html { -webkit-tap-highlight-color: rgba(0,0,0,0); }
3.單個a元素新增ontouchstart空事件
<a ontouchstart="">Click me</a>
4.所有a元素新增touchstart空事件
var a=document.getElementsByTagName(‘a’); for(var i=0;i<a.length;i++){ a[i].addEventListener(‘touchstart’,function(){},false); }
