阻止html中onclick事件冒泡，处理方法上多加事件一个参数，不需要传值。
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> ???<title></title> ???<meta charset="utf-8" /> ??</head><body> ???<div style=‘background:red;width:200px;height:50px‘ onclick=‘a()‘> ???????<input type=‘button‘ value=‘ok‘ onclick=‘b()‘></input> ???</div> ??<script type="text/javascript"> ????function a(e){ ???????alert("this div") ????} ?????function b(e){ ???????alert("this button") ???????if(e&&e.stopPropagation){ ???????????e.stopPropagation(); ???????}else{ ???????window.event.cancelBubble =true; ???????} ????} ???</script></body></html>结果：阻止，button按钮上的click事件冒泡
