When extreme changes in context are explicitly identified before they occur, then the users can determine if they wish to proceed or so they can be prepared for the change: not only they will not be confused or feel disoriented, but more experienced users can better decide how to open such links (in a new window or not, in the same window, in a new tab or not, in "background" or not). The purpose is to warn users of context changes to minimize confusion on the user's part: changing the current window or popping up new windows can be very disorienting to users (in the case of a popup, no toolbar provides a "Previous" button to get back to the previous window). Let windowObjectReference = null // global variable function openRequestedTab ( url, windowName ) Same-origin policy See rel="noreferrer" for more information. If this feature is set, the browser will omit the Referer header, as well as set noopener to true. When noopener is used, non-empty target names, other than _top, _self, and _parent, are treated like _blank in terms of deciding whether to open a new browsing context. If this feature is set, the new window will not have access to the originating window via Window.opener and returns null. Specifies the distance in pixels from the top side of the work area as defined by the user's operating system where the new window will be generated. Specifies the distance in pixels from the left side of the work area as defined by the user's operating system where the new window will be generated. Specifies the height of the content area, including scrollbars. Specifies the width of the content area, including scrollbars. To enable the feature, specify popup either with no value at all, or else set it to yes, 1, or true.Įxample: popup=yes, popup=1, popup=true, and popup all have identical results. Note: Specifying any features in the windowFeatures parameter, other than noopener or noreferrer, also has the effect of requesting a popup. If popup is not enabled, and there are no window features declared, the new browsing context will be a tab. The UI features included in the popup window will be automatically decided by the browser, generally including an address bar only. If this feature is enabled, it requests that a minimal popup window be used. The following options are supported: popup These features include options such as the window's default size and position, whether or not to open a minimal popup window, and so forth. windowFeatures OptionalĪ string containing a comma-separated list of window features in the form name=value - or for boolean features, just name. This name can be used as the target attribute of or elements. The special target keywords, _self, _blank, _parent, and _top, can also be used. If the name doesn't identify an existing context, a new context is created and given the specified name. target OptionalĪ string, without whitespace, specifying the name of the browsing context the resource is being loaded into. If an empty string ( "") is specified or this parameter is omitted, a blank page is opened into the targeted browsing context.
