jquery 1.9.1 和 MacBook Air 上的 Safari，.on() 事件处理程序不起作用

Question

我正在使用以下代码：

$jq191('html, body').on('DOMMouseScroll mousewheel touchmove', '.fancybox-overlay', function( e ){ e.preventDefault(); e.stopPropagation(); });

我也试过：

$jq191('html, body').on('DOMMouseScroll mousewheel touchmove', function( e ){ e.preventDefault(); e.stopPropagation(); });

但事件处理程序从未在带有safari的macbookair上触发。我不知道我做错了什么。如果我将html，body设置为溢出：隐藏，body不会滚动，但我不希望在删除/添加垂直滚动条时，花哨的框会移动body的内容。谢谢

编辑在关于文档的jquery中，它说：如果省略了选择器或选择器为null，则将事件处理程序称为直接绑定或直接绑定。每当事件发生在所选元素上时，无论是直接发生在元素上还是子代（内部）元素中的气泡，都会调用处理程序

那么，为什么这不能阻止冒泡事件将一个粉丝框一直滚动到身体？（使用：$jq191（'html，body'）.on（'DOMouseSoll鼠标滚轮touchmove'，函数（e）｛e.preventDefault（）；e.stopPropagation（）；｝）；）

另一件奇怪的事情是，当滚动覆盖时（这是有效的），当调试器打开时，它会在事件上中断，但在中断事件后，正文会立即滚动。可能是个虫子。

编辑做了一个小提琴http://jsfiddle.net/Sa7AP/如果你在粉色框内滚动chrome和safari，一旦你到达粉色框的末尾，并继续滚动，背景也会滚动。当我在fancybox中滚动时，我试图阻止背景的滚动。

Answer 1

试试这个

$jq191('body').on('DOMMouseScroll mousewheel touchmove', '.fancybox-overlay', function( e ){ e.preventDefault(); e.stopPropagation(); });

或

$jq191('html body').on('DOMMouseScroll mousewheel touchmove', '.fancybox-overlay', function( e ){ e.preventDefault(); e.stopPropagation(); });

好的，我找到了另一个SO问题，并使用了他们的一个稍微修改过的版本：jsfiddle：http://jsfiddle.net/Sa7AP/20/

    var scrollTopHeight= el[0].scrollHeight - el[0].clientHeight;
    var delta= event.originalEvent.wheelDelta || -event.originalEvent.detail;
    if ( ( el.scrollTop() <= 0 &&  delta > 0 ) || ( el.scrollTop() >= scrollTopHeight && delta < 0 ) ) {

    return false;
}
jQuery('.fancybox-wrap').on('DOMMouseScroll mousewheel touchmove', function(e) { if( isBeyond( this, e) )
