How to push diffs of data (possibly JSON) to a server?

I am going to be periodically pushing a set of text-based data from a web-page to a server , probably as JSON. For every push, none, some or all of the data may have changed. To reduce the amount of data I have to send over the wire I would want to only send a diff of the changes in each push.

Syntax highlighting code with Javascript

What Javascript libraries can you recommend for syntax highlighting <code> blocks in HTML? (One suggestion per answer please). StackOverflow使用Prettify库。 I recently developed one called rainbow. The main design goal was to make the core library really small and make it really easy for developers to extend. See http://rainbowco.de. SyntaxHighlighter可用作GitHub项目。

使用Javascript语法高亮显示代码

您可以推荐哪些Javascript库用于语法突出显示HTML中的<code>块? (请每个答案一个建议)。 StackOverflow使用Prettify库。 我最近开发了一种叫做彩虹的产品。 主要的设计目标是使核心库非常小,使开发人员可以很容易地扩展。 见http://rainbowco.de。 SyntaxHighlighter可用作GitHub项目。

Javascript MIME Type

Based on this question: jQuery code not working in IE So text/javascript is used in HTML documents so Internet Explorer can understand it. But I'm wondering, when would you use application/javascript , and more importantly, why would you use it instead of text/javascript ? In theory, according to RFC 4329, application/javascript . The reason it is supposed to be application is not anyt

Javascript MIME类型

基于这个问题:jQuery代码不能在IE中工作 所以在HTML文档中使用了text/javascript ,因此Internet Explorer可以理解它。 但我想知道,你什么时候会使用application/javascript ,更重要的是,你为什么要用它来代替text/javascript ? 理论上,根据RFC 4329, application/javascript 。 它应该是application的原因与该类型是否可读或可执行无关。 这是因为有语言/类型本身定义的自定义字符集确定机制,而不仅仅是泛型cha

What is the Prototype equivalent of JQuery's $(element).text()?

Given the following snippet: <div id="myDiv"> This is my text <span>with a span</span> </div> JQuery can get the interior string with: $('#myDiv').text(); Is there a more intuitive way in Prototype than: $('myDiv').pluck('innerHTML').first().stripTags(); Hum, doesn't $('myDiv').innerHTML.stripTags(); work ? Edit: if you really want a text() method in Pr

JQuery的$(element).text()的Prototype等价物是什么?

鉴于以下片段: <div id="myDiv"> This is my text <span>with a span</span> </div> JQuery可以得到内部字符串: $('#myDiv').text(); Prototype中有一种更直观的方法: $('myDiv').pluck('innerHTML').first().stripTags(); 哼,不 $('myDiv').innerHTML.stripTags(); 工作? 编辑:如果你真的想在Prototype中使用text()方法,你可以这样做: Class.extend(Element, { text: functi

$(document).ready() and script locations

I'd like to know how $(document).ready() works, along with scripts in general. Say I have scripts that are at the bottom of the page (for performance reasons I'm told?). As an example: say you have a link and you need to prevent it's default action ( preventDefault() ). If the script is at the bottom of the page, isn't it possible that the user can see the page and click the li

$(document).ready()和脚本位置

我想知道$(document).ready()是如何工作的,以及一般的脚本。 假设我有脚本在页面底部(出于性能方面的原因,我被告知?)。 举个例子:假设你有一个链接,你需要阻止它的默认动作( preventDefault() )。 如果脚本位于页面底部,用户是否有可能看到该页面并在浏览器知道不遵循该链接之前单击该链接? “头部”部分中的脚本在脚本标签加载到浏览器的位置进行评估(即在主体之前)。 文档末尾的脚本标签在浏览器遇到浏览器分
