JavaScript Popup Windows
JavaScript popups are handy to display help information or to zoom in an Image. There are different types of Popups. The first type is a new browser window opened using the window.open() function. Such types of Popup windows were overused and exploited by many websites during the earlier days of the web. This resulted in the later versions of browsers blocking popup windows. Eventually, popup windows became almost extinct now. Automatically opening popup windows is considered a very bad practice.
