Yes, there are maps, and chats, and Twitter, and portals, and the like. We're just seeing the beginnings of Ajax use. What an all-encompassing question! :-) It goes entirely outside of Proto/Scripty scope, it's just Ajax-related. How will the paradigm shift from ajax will happen? How far can we push the walls of ajax applications beyond maps and chats? How far can we implement ajax on mobile? And how will prototype and scriptaculous help? I am waiting to know the future scope of this technology. Many number of sites are using the technology to implement number of facilities in a web page -starting from email validations to chatting. Writing to read-only properties is supposed to throw an exception when you are using strict mode.AJAX has been used in common in web applications. Writing to read-only properties in strict mode will throw an error You will have to provide your own serialization method, for example you could do the following: function stringifyDOMObject(object)
For example, this can affect your site if you are trying to serialize an object such as Push Notification's PushSubscription.Ĭhrome 42 and earlier the following would have worked: > JSON.stringify(subscription) Ĭhrome 43 onwards will not serialize the properties that are on defined on the prototype and you will be returned an empty object. JSON.stringify doesn't serialize DOM properties that are on the prototype. JSON.stringify will no longer serialize DOM Attributes As the library developer, you would naturally want to use the prototype as follows to create an efficient polyfill: fineProperty(HTMLDivElement.prototype, "isSuperContentEditable", For example, it will enable you to implement polyfills that allow you to efficiently emulate functionality missing in some browsers and JavaScript libraries that override default DOM attribute behaviors.įor example, a hypothetical W3C specification includes some new functionality called isSuperContentEditable and the Chrome Browser doesn't implement it, but it is possible to "polyfill" or emulate the feature with a library. Increases the hackability of DOM programming.Allows you to consistently and efficiently create getters/setters on every DOM Object.Improves compatibility across the web (IE and Firefox do this already) via compliance with the spec.The new behavior is positive in many ways. An Attribute in this article is not an HTML Attribute such as class on an image element. Note: The use of the word Attribute and Property are used interchangeably in this post, the ECMA Script spec defines 'Properties' that have 'Attributes'. Edit: clarified Older WebKit based browsers, are currently not compatible with the spec, however Safari now is. This change, implemented in Chrome 43 - (Beta as of mid April 2015) - brings Chrome more in line with the Web IDL Spec and other browsers’ implementations, such as IE and Firefox. The Chrome team recently announced that we are moving DOM properties to the prototype chain.
