With JavaScript enabled, we can loop over all links with a class of popup and attach an onclick event handler that calls window.open() with the link s href property. If JavaScript is disabled, the link functions normally and the user can still see the info.html page. We get the benefit of graceful degradation in the absence of JavaScript as well as separation of behavior from presentation. In some cases, the examples in this chapter show what s most easily displayed in book format; in practice, it s worthwhile following the unobtrusive JavaScript principles. For more information on unobtrusive JavaScript, see Jeremy Keith s excellent book, DOM Scripting: Web Design with JavaScript and the Document Object Model.

If set to TRUE, menus generated by the GtkUIManager will have tear-off menu items unless they are pop-up menus. The XML string that is used to generate the menu or toolbar user interface. This was either explicitly set or loaded from a file.

If you re thinking that the previous example contains a lot of code for a simple Ajax request, you re not alone. The simple act of creating the XMLHttpRequest object isn t consistent across browsers. We ll see how to clean that up later. First, let s see how this example would be applied in ASP.NET Web Forms.

In general, browsers are expected to honor the MIME type of the document as specified in the Content-Type HTTP header. In particular, one would expect that a browser would always render a document with Content-Type: text/plain as plain text, without interpreting HTML tags in the document.

The horizontal adjustment of the viewport used for native scrolling support. The type of shadow that is drawn around the viewport s child widget. The vertical adjustment of the viewport used for native scrolling support.

If we take the example in listings 12.1 and 12.2 and apply it to Web Forms, we may hit some bumps. First is the issue of the actual web request. Earlier we specified the URL to be get_message.html, but in reality this is probably going to be a dynamic page. Let s assume that we used get_message.aspx and that the message came from a database. ASP.NET pages go through the page lifecycle events and render the template (.ASPX)

If set to TRUE, GTK+ will draw directly on the GtkWidget. If set to TRUE, the GtkWidget will be able to become the window s default widget. If set to TRUE, the GtkWidget will be able to accept the window s focus. If set to TRUE, the widget is not derived directly from GtkWidget. A bitmask of all of the events from GdkEventMask that the widget will receive. A bitmask of all extension events from GdkExtensionMode that the widget will receive. If set to TRUE, the GtkWidget is currently the default widget of its parent window. If set to TRUE, the GtkWidget is currently the widget with focus.

This is not the case for Internet Explorer, which has a feature, referred to as content-type sniffing or MIME-type detection, where it scans the beginning of a document for HTML tags. If it finds substrings that appear to be HTML tags, it assumes that the publisher of the document meant to serve an HTML document, and ignores the document s specified content type and interprets the document as HTML. (For more information, see the Microsoft MSDN article, MIME Type Detection in Internet Explorer, at http://msdn.microsoft.com/workshop/ networking/moniker/overview/appendix_a.asp). This can result in considerable headaches for the developer of an application that renders non-HTML documents from untrusted sources. For example, a web-based e-mail application may have a feature that allows users to view an e-mail s attachments in a separate browser window. A malicious attachment of content type text/plain that contains script tags near the beginning would cause the malicious script to be executed if viewed by a user in Internet Explorer, even if the server served the document with the correct Content-Type: text/plain header. More problematically, some versions of Internet Explorer even do this for documents with image content types. If an image is not really a valid image file, but rather contains HTML tags near the beginning, Internet Explorer will reinterpret the image document as HTML, and execute any script incorporated in the document. Note that it does so only if the image is

that we ve defined. These templates represent a full HTML document, but we only want to render the message. We could instead use a custom IHttpHandler to intercept a different file extension and not use the page template. This would look something like listing 12.3.
