有利于加快加载速度（已经得到验证）。

修改图片src更新图片

<div style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; LINE-HEIGHT: 21px; PADDING-TOP: 0px">
<span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'">$(imageobj).attr('src', $(imageobj).attr('src') </span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'">+</span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'"> '</span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'">?</span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'">' </span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'">+</span><span style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; MARGIN: 0px; COLOR: #000000; PADDING-TOP: 0px; FONT-FAMILY: 'Courier New'"> Math.random() );</span>
</div>

这是很实用的技巧，曾经有人问明河，为什么他已经修改了图片的src，但图片没变化呢？原因在于缓存，给图片路径后加个随机数参数即可。

JavaScript在行动中：现实世界中的示例和项目Apr 19, 2025 am 12:13 AM

JavaScript在现实世界中的应用包括前端和后端开发。1)通过构建TODO列表应用展示前端应用，涉及DOM操作和事件处理。2)通过Node.js和Express构建RESTfulAPI展示后端应用。

JavaScript和Web：核心功能和用例Apr 18, 2025 am 12:19 AM

JavaScript在Web开发中的主要用途包括客户端交互、表单验证和异步通信。1)通过DOM操作实现动态内容更新和用户交互；2)在用户提交数据前进行客户端验证，提高用户体验；3)通过AJAX技术实现与服务器的无刷新通信。

了解JavaScript引擎：实施详细信息Apr 17, 2025 am 12:05 AM

理解JavaScript引擎内部工作原理对开发者重要，因为它能帮助编写更高效的代码并理解性能瓶颈和优化策略。1)引擎的工作流程包括解析、编译和执行三个阶段；2)执行过程中，引擎会进行动态优化，如内联缓存和隐藏类；3)最佳实践包括避免全局变量、优化循环、使用const和let，以及避免过度使用闭包。

Python vs. JavaScript：学习曲线和易用性Apr 16, 2025 am 12:12 AM

Python更适合初学者，学习曲线平缓，语法简洁；JavaScript适合前端开发，学习曲线较陡，语法灵活。1.Python语法直观，适用于数据科学和后端开发。2.JavaScript灵活，广泛用于前端和服务器端编程。

Python vs. JavaScript：社区，图书馆和资源Apr 15, 2025 am 12:16 AM

Python和JavaScript在社区、库和资源方面的对比各有优劣。1)Python社区友好，适合初学者，但前端开发资源不如JavaScript丰富。2)Python在数据科学和机器学习库方面强大，JavaScript则在前端开发库和框架上更胜一筹。3)两者的学习资源都丰富，但Python适合从官方文档开始，JavaScript则以MDNWebDocs为佳。选择应基于项目需求和个人兴趣。

从C/C到JavaScript：所有工作方式Apr 14, 2025 am 12:05 AM

从C/C 转向JavaScript需要适应动态类型、垃圾回收和异步编程等特点。1）C/C 是静态类型语言，需手动管理内存，而JavaScript是动态类型，垃圾回收自动处理。2）C/C 需编译成机器码，JavaScript则为解释型语言。3）JavaScript引入闭包、原型链和Promise等概念，增强了灵活性和异步编程能力。

JavaScript引擎：比较实施Apr 13, 2025 am 12:05 AM

不同JavaScript引擎在解析和执行JavaScript代码时，效果会有所不同，因为每个引擎的实现原理和优化策略各有差异。1.词法分析：将源码转换为词法单元。2.语法分析：生成抽象语法树。3.优化和编译：通过JIT编译器生成机器码。4.执行：运行机器码。V8引擎通过即时编译和隐藏类优化，SpiderMonkey使用类型推断系统，导致在相同代码上的性能表现不同。
