js阻止事件冒泡

Posted 2020-10-06 13rj1115

兼容火狐、谷歌等浏览器

    function stopEvent(event){ //阻止冒泡事件
        //取消事件冒泡
        var e=arguments.callee.caller.arguments[0]||event; //若省略此句，下面的e改为event，IE运行可以，但是其他浏览器就不兼容
        if (e && e.stopPropagation) {
            // this code is for Mozilla and Opera
            e.stopPropagation();
        } else if (window.event) {
            // this code is for IE
            window.event.cancelBubble = true;
        }
    }
