JSCharts.js是一款专为JavaScript开发者设计的轻量级图表绘制工具,它采用完全客户端脚本实现,无需依赖额外的插件,只需将JSCharts.js文件引入到HTML页面中,即可轻松创建各种类型的图表,如条形图、饼图和简单线图。其设计初衷是简化图表制作过程,提高开发效率。 在实际使用中,JSCharts.js提供了直观易用的实施步骤: 1. 脚本引入: 首先,要在页面的`<head>`部分引入JSCharts.js的核心脚本,确保浏览器兼容性。由于脚本包含主要的图表库和针对Internet Explorer所需的图形和canvas功能(在Firefox、Opera和Safari等现代浏览器中这些功能已原生支持),因此只需引用这一文件即可: ```html <script type="text/javascript" src="jscharts.js"></script> ``` 如图1.1所示,这是将脚本引入页面的基本示例。 2. 容器设置: 创建图表时,需要一个独一无二的`<div>`元素作为容器,用于承载绘制完成的图表。这个容器应当明确指定一个ID,以便后续的脚本操作: ```html <div id="chartcontainer">This is just a placeholder</div> ``` 这个ID允许开发者通过JavaScript精准地定位到要渲染图表的区域。 JSCharts.js的强大之处在于其高度可定制性。用户可以根据需求自定义图表样式、数据格式以及交互行为。通过提供XML、JSON或JavaScript数组的数据格式选项,开发者可以轻松处理不同类型的数据源。此外,它还支持对文本的添加和编辑,使得图表信息传递更加直观。 JSCharts.js是一个简洁而强大的JavaScript图表库,它简化了前端开发者的图表绘制任务,为创建美观且功能丰富的图表提供了一种灵活且高效的解决方案。通过简单的代码集成和配置,用户能够快速构建出满足业务需求的各种图表。

JavaScript is no longer to be feared or loathed – the world’s most popular and ubiquitous language has evolved into a respectable language. Whether you’re writing frontend applications or server side code, the phenomenal features from ES6 and beyond – like the rest operator, generators, destructuring, object literals, arrow functions, modern classes, promises, async, and metaprogramming capabilities – will get you excited and eager to program with JavaScript. You’ve found the right book to get started quickly and dive deep into the essence of modern JavaScript. Learn practical tips to apply the elegant parts of the language and the gotchas to avoid. JavaScript is a black swan that no one, including the author of the language, thought would become a popular and ubiquitous language. Not long ago, it was the most hated and feared language you could use to program the web. JavaScript ES6 and beyond has gone through a significant makeover. Troublesome features have been replaced with better, elegant, more reliable alternatives. This book includes many practical examples and exercises to help you learn in depth. It will not bore you with idiosyncrasies and arcane details intended for bad interview questions. Instead, it takes you into key features that you can readily use in your day-to-day projects. Whether you program the frontend or the server side, you can now write concise, elegant, and expressive JavaScript with newer features like default parameters, template literals, rest and spread operators, destructuring, arrow functions, and generators. Take it up a notch with features like infinite series, promises, async, and metaprogramming to create flexible, powerful, and extensible libraries. While the evolved features of the language will draw you in, the hundreds of examples in this book will pin the concepts down, for you to use on your projects. Take command of modern JavaScript and unlock your potential to create powerful applications. What You Need: To try out the examples in the book you will need a computer with Node.js, a text editor, and a browser like Chrome installed in it.
