Use of Window.opener and window.open

Window.opener refers to the window that invokes the Window.Open method. Window.opener returns a reference to the window that created the current window, such as clicking on a link on a.htm and opening the b.htm, and then we're going to enter a value on the b.htm and give it a TextBox with an ID of "name" on the a.htm, It can be written as: Window.opener.document.getElementById ("name"). Value = "input data"; In the work is mainly used to solve the partial submission. If you open a page in the main window and want to refresh the main window with this, the Window.opener of the open page is equivalent to the window of the main windows. The main window of the refresh you can use Window.opener.location.reload (); If you use a virtual directory: such as struts *.do will prompt you to retry you can change to this window.opener.yourformname.submit () just fine. In the application there is a case in the A window open b window, in the b window after the completion of the b window, and automatically refresh a window.

The most basic pop-up Code: window.open (' page.html '), after setting the popup window window.open (' page.html ', ' newwindow ', ' height=100, width=400, Top=0, Left=0, Toolbar=no, Menubar=no, Scrollbars=no, Resizable=no, Location=no, Status=no ')//This sentence is written in a line of code

windows.location.href= "/url"
The current page opens the URL page;
Window.location.href=window.location.href, and Window.location.Reload () both refresh the current page. The difference is whether there is data to submit. When there is data submitted, Window.location.Reload () will prompt whether to commit, window.location.href=window.location.href, or submit data to the specified URL.
