我如何防止滚动被阻止滚动的子格

Question

可能是一个基本的问题，但有一个大的身体，我可以围绕滚动和身体里面我有一对夫妇的孩子的div这是滚动自己。

当我滚动身体周围，光标打击的孩子之一的div就会卡住，并开始滚动孩子DIV来代替。当我到达子div的可滚动结尾时，我将只能继续滚动body/parent。

我想在孩子的div滚动，如果我是滚动体被忽略。如果这是不可能的，那么我希望至少只能在子div内按下鼠标按钮的时候才能滚动子div，否则就会滚动主体。

这里是行为的一个例子：JSFiddle

位置是固定的position: absolute

.area{ 
    overflow:auto; 
    max-height:250px; 
    width:300px; 
    background:#000; 
    color:#FFF; 
    position: absolute; 
    bottom:0px; 
} 

Answer 1

尝试这样的事情。如果用户没有点击进入div，那么就不会被滚动的div而是document滚动。

var scrollArea = false; 
 
$('.area').on('mousewheel DOMMouseScroll', function (e) { 
 
    var event = e.originalEvent; 
 
    var d = -event.wheelDelta || event.detail; 
 
    if(scrollArea) 
 
    { 
 
     this.scrollTop += d; 
 
    } 
 
    else 
 
    { 
 
    \t $(document).scrollTop($(document).scrollTop()+d); 
 
    } 
 
    e.preventDefault(); 
 
}); 
 

 
$('.area').on('click', function (e) { 
 
\t scrollArea = !scrollArea; 
 
});

.area{ 
 
    overflow:auto; 
 
    max-height:250px; 
 
    width:300px; 
 
    background:#000; 
 
    color:#FFF; 
 
    position: absolute; 
 
    bottom:0px; 
 
}
