Internet Explorer 10 Platform Preview 1

Microsoft n'aura finalement pas mis longtemps à dévoiler la 1ère Platform Preview d'Internet Explorer 10. En effet, c'est lors du MIX'11 que l'éditeur de Redmond a dévoilé les nouveautés du futur navigateur de Windows. Malheureusement, il n'y a que des changements internes au moteur Trident à se mettre sous la dent, notamment un changement de l’interprétation de la balise <object> qui se cale sur celle des navigateurs Mozilla.

Voici la liste des changements :

Event object's 'trusted' property
In recent changes to the W3C DOM Level 3 Events specification's Last Call feedback, the working group elected to change the 'trusted' property to 'isTrusted' to match the property of the same name and semantics in Mozilla browsers. IE's implementation of this property has been adjusted to match.

DOM Programmability
Invoking cached DOM functions without using the dot (.) notation and without using call/apply/bind now throws script errors. The previously supported legacy function invocation pattern has been removed for better interoperability and standards support:
var g = document.getElementById; g(‘test’); // Now throws an exception
Enumeration of DOM objects previously only included properties and event handlers. With IE9 and IE10 standards mode, enumeration now includes functions as well. Support for invoking collection objects as functions (rather than array-indexing): document.images(0) has been removed from the following collection objects: HTMLFormElement, window.frames, document.frames, NodeList.

HTCs / VBScript
HTML Components (HTC) and VBScript code when used inside of an IE9 or IE10 standards mode page are no longer executed in compatibility view. Consequently, DOM APIs used by the HTC or VBScript code now behave according to the IE standards mode version of the same APIs.

DOM Properties in Attributes Collection
Properties set on DOM objects no longer appear in the attributes collection (NamedNodeMap) and vice versa in IE9 or IE10 standards mode. This change also aligns IE’s programmability model with current standards and interoperability.

Comme pour les Platform Previews d'IE9, le navigateur s'installe dans un dossier séparé afin de ne pas gêner l'autre version.
