window.open (URL, name, features, replace)

Arguments -parameters

URL Optional String parameter that points to the URL of the document to display in a new window. If this argument is omitted, or if the argument is an empty string, the new window does not display the document.

name is an optional string parameter that sets the name of the new window. A window of the same name can only create one, and the name cannot be the same if you want to create multiple windows.

features Optional string parameter, which is used to set the function of the new window. Because the parameter is optional, if the parameter is not specified, the new window has all the standard features.

Replace to choose a Boolean parameter that sets how the operation history is saved in the new window. true -Create a new history false-replace old history

Returns -return value a reference to a newly created or existing Window object based on the name parameter.

Description -Description

The open () method can look for an existing or new browser window. If the name parameter specifies an existing Liu browser window, a reference to that window is returned. The returned window will display the document specified in the URL, but the features parameter will be ignored. The open () method is the only way in JavaScript to get the window reference of a viewer by name.

The open () method creates a new browser window if the name parameter is not specified, or if there is no window that has the names specified by the name parameter.

The name parameter is used to specify the names of the new windows, which must consist of letters, numbers, and underscore characters.  It can be pointed to by the <a> tag or <form> tag in the HTML document.

When you use the window.open () method to load a new document into a named window that already exists, you can set how the history is saved by using the Replace parameter ... If this argument is true, the history of the new document supersedes the history of the old document. If the parameter is false or if this parameter is not specified, the new file will establish its own entry in the window's browsing history. This parameter provides a way to Location.replace () the same functionality.

Do not confuse "window.open ()" and "Document.open ()", which is two completely different methods. To make the code clearer, you can replace "open ()" with "window.open ()". When you define an event handler as an HTML attribute, "open ()" is generally interpreted as "document.open ()", so you must use "window.open ()" In this case.

Window Features -Windows features

　 The feature parameter is a comma-separated list of features. If the parameter is empty or if the parameter is not specified, the new window will have all the functionality. On the other hand, if the feature parameter specifies only one item or several features, other features that are not specified will not appear in the new window. The string cannot contain any spaces or other empty strings.

Format of each element in the list: function [= value]
