我知道有很多文字,但我的所有问题都是粗体,并且有一个JSFiddle示例,您可以立即处理.

因为我还没有找到任何内置功能,所以
我必须创建一个hasScroll函数,检查元素是否有滚动条,

    if(typeof axis == "undefined" || axis == "y") overflowAxis = this.css("overflow-y");
    else overflowAxis = this.css("overflow-x");

    var bShouldScroll = this.get(0).scrollHeight > this.innerHeight();

    var bAllowedScroll = (overflow == "auto" || overflow == "visible") ||
                         (overflowAxis == "auto" || overflowAxis == "visible");

    var bOverrideScroll = overflow == "scroll" || overflowAxis == "scroll";

    return (bShouldScroll && bAllowedScroll) || bOverrideScroll;
};

和一个inScrollRange函数,检查执行的点击是否在滚动范围内.
