Window. Close () Close the specified browser window. If the close () function is called without a window reference, JavaScript closes the current window. In event processing Program You must specify window. Close () instead of close (). Because of the total scope of static JavaScript objects, the call to close () without the object name is equivalent to document. Close (). If you execute the close () method to close a window that is not opened by a script program, a confirmation dialog box appears asking the user to choose whether to close the window. If there is only one record in the history list, no dialog box will appear in navigator. However, if you use close () to exit the final running browser instance, the confirmation dialog box appears. That is to say, I use window. open a window, and then execute window in the Opened Window. close, then the user is not prompted "Yes, no close"; if you open a window directly, and execute window in it. close, then the user will be prompted to select "whether to close ". In addition, you can specify window. returnvalue in the window opened by window. Open. If this window is closed, VAR Param = Window. Open ("thiswindow.html ");
The value of Param is the value of window. returnvalue you set. <! -- The default close method in IE. in IE, a dialog box is displayed for confirmation. -->
<A href = "javascript: window. Close ()"> default close </a>
<! -- In IE6, window. opener can be used to bypass this restriction -->
<A href = "javascript: window. operner =" X "; window. Close ()"> close IE6 </a>
<! -- This method can be used in IE7 -->
<A href = "javascript: window. Open ('', '_ top'); window. Top. Close (); "> close IE7 </a>
