  Changing settings on the browser from the server

  Jan 07, 2004 09:16 PM|LINK

  Common questions: How do I change the header and footer on IE when printing? How do I change the elements on the current browser window? To both of these, the answer is "You can't." I wrote this FAQ because there is a general misunderstanding about the relationship between the browser and the server. The browser is designed to protect the computer it's on against invasive actions from the server. Its a private environment. The server is not provided any DOM/DHTML methods or JavaScript statements that break this rule. To maintain this privacy, your JavaScript can only do these things to the browser: - modify the contents of the current window. Since this window will only contain HTML and code supplied by the server, you aren't editing anything on the computer beyond that HTML. - open a new window. (This action can define attributes of the window when using the DOM/DHTML method window.open().) - actions that print or move through page history (these don't affect anything outside the current window) - modify the size and position of the current window. For the last 3 of these, see the documentation on the window and history classes. If you look at the navigator object (which describes some qualities of the IE browser), you will see that its properties and methods are "readonly". For more on the DHTML classes, start here.
