问题 I edited my question What is a vendor specific extension? A vendor specific extensions can start with a “-” (dash) or a “_” (underscore), usually followed by an abbreviation of the company or the browser project the extension is specific for, f.i. “-moz-” for Mozilla browsers, or “-webkit-” for WebKit based browsers.

traverse through each file in SD card using phonegap file api

由 落爺英雄遲暮 提交于 2019-12-07 13:13:09
问题 I want to traverse through each file in the SD card inside all the directories and sub directories using the FILE API of phonegap (which is the w3c file api actually). I have to perform a certain set of operations on these files by looking at their nature. I donot want to search for specific types of files, but traverse through each file in a sequential manner. Can someone please help me with this? Just a basic loop framework with the necessary requirements for the traversal would be a great

Is XRX the only full stack web application “framework” that's totally W3C?

由 强颜欢笑 提交于 2019-12-07 11:41:02
问题 XRX means an application where the front end is written entirely in XML dialects and the back end is written entirely in XML dialects and data is passed between them as XML over REST. Is it correct that this is the only web application stack that is composed solely of technologies maintained by the W3C? 回答1: I think the best way to answer this is that XRX the only web architecture that I am aware of that incorporates two important web standards: XQuery and XForms, to create portable web

由 ♀尐吖头ヾ 提交于 2019-12-07 07:02:08
问题 In HTML 4.01 certain end tags are forbidden , that means it in not valid markup to have them, e.g.: Invalid Valid =================== ================= <BR/> <BR> <BR></BR> <IMG src="..."/> <IMG src="..."> <IMG ...></IMG> <INPUT ... /> <INPUT ...> <INPUT ...></INPUT> In the HTML 4.01 specification the indication of an end tag being optional or forbidden is nicely summarized in the index of elements: Name Start Tag End Tag AREA F BASE F BASEFONT F BODY O O BR F COL F COLGROUP O DD O DT O FRAME

HTML5 LocalStorage size

由 那年仲夏 提交于 2019-12-07 03:40:00
问题 Can anyone explain me the size of window.localStorage (for example, 5MB in Firefox) is 5MB for each scope or only for all? 回答1: Regarding Firefox, quoting fron a John Resig article (posted January 2007):: Storage Space It is implied that, with DOM Storage, you have considerably more storage space than the typical user agent limitations imposed upon Cookies. However, the amount that is provided is not defined in the specification, nor is it meaningfully broadcast by the user agent. If you look

Is anyone using XForms in their web applications?

由 萝らか妹 提交于 2019-12-07 03:05:43
问题 A few years ago we started playing around with XForms from the W3C for a web app which required hundreds of custom forms. As they aren't currently supported natively by the major browsers, what parsers/tools are you using on your projects today? I'm not really interested in plugins - this needs to be something server side that emulates XForms. 回答1: We use XForms for creating user interfaces for SOAP-based web services. Currently we settled with Chiba XForms engine (http://chiba.sourceforge

由 前提是你 提交于 2019-12-06 17:02:28
问题 I'm not sure about the convention regarding headings in HTML 5 but I wanted to know if I could add a <small> in a <h3> , like this (this could apply to any tag inside any heading tags): <h3>Payment details <small>(this is your default card)</small></h3> Many Thanks 回答1: Yes, that markup validates. You can check it yourself on http://validator.w3.org/ Something to be aware of with HTML5 though is a change to the notion of block-level elements: https://developer.mozilla.org/en/HTML/Block-level
