问题描述
你好，
我做了一个弹出窗口，默认情况下隐藏并在窗口上触发点击时打开.必须在触发事件的任何地方显示弹出窗口.但是有一些限制:
弹出窗口必须显示在当前可见窗口.意思是，如果我点击了窗口的最右侧，那么弹出窗口必须显示在点击位置的右侧以避免滚动.
李>如果窗口有滚动，无论是否滚动，它都应该显示在窗口的可见部分.
在我目前的代码中一切正常，除非窗口有滚动.如果向下滚动并单击窗口中间，则弹出窗口显示在窗口外当前显示区域......................................

I have done a popup which is by default hidden and opened whenever a click is triggered on window. Popup must be shown at wherever the event is triggered.But there are some constraints:
Popup must be shown at current visible window.Meaning,If I clicked at right most part of the window then,popup must be shown to right side of the clicked position to avoid scrolling.
If window has scrolling, irrespective of scrolling it should be shown at visible part of the window.
Everything is working fine in my present code except in the case,if window has scrolling.
If scroll down and click on the middle of the window, popup is displayed at out of the window current display area.........................
