在iOS上的webapp上,我有一堆按钮只响应touchend(作为移动游戏中点击延迟的快捷方式).当我在处理程序中粘贴警报时,即使他们有自己的处理程序,随后点击页面上任何其他按钮也会触发此原始处理程序.这是一些说明问题的示例代码:

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="default" />
<script type="text/javascript">
function clickAlert(evt) {
alert('btn clicked');
}
function clickData(evt) {
var div;
div = document.getElementById('data');
div.innerHTML += 'btn2 click: ' + (new Date().getTime()) + '<br/>';
}
function loadHandler() {
var btn;
btn = document.getElementById('btn-click-alert');
btn.addEventListener('touchend', clickAlert, false);
btn = document.getElementById('btn-noclick');
btn.addEventListener('touchend', clickData, false);
}
window.addEventListener('load', loadHandler, false);
</script>
</head>
<body>
<button id="btn-click-alert">Click to alert</button>
<button id="btn-noclick">No alert here</button>
<div …
