具体描述

Book Description

The Google Maps API remains one of the showcase examples of the Web 2.0 development paradigm. Beginning Google Maps Applications with Rails and Ajax: From Novice to Professional is the first book to comprehensively introduce the service from a developer perspective, showing you how you can integrate mapping features into your Rails-driven web applications.

Proceeding far beyond simplistic map display, you'll learn how to draw from a variety of data sources such as the U.S. Census Bureau's TIGER/Line data and Google's own geocoding feature to build comprehensive geocoding services for mapping many locations around the world.

The book also steers you through various examples that show how to encourage user interaction such as through pinpointing map locations, adding comments, and building community-driven maps. You'll want to pick up a copy of this book because

* This is the first book to comprehensively introduce the Google Maps application development using the Rails development framework.

* You'll be introduced to the very latest changes to the Google Maps API, embodied in the version 2 release.

* It is written by four developers actively involved in the creation of location-based mapping services.

评分

我特别欣赏这本书的章节安排,它循序渐进地引导读者从零基础开始构建基于Google Maps和Rails的应用。一开始,作者并没有直接跳到复杂的代码实现,而是花了大篇幅来介绍Rails的基础知识,包括MVC架构、RESTful原则以及常用的Ruby语法,这对于我这种初学者来说简直是福音。我之前尝试过一些Rails的教程,但往往因为基础不扎实而难以深入。这本书的讲解清晰易懂,每一个概念都配有生动的例子,让我能够快速理解和掌握。

评分

书中对于API的使用也做了非常细致的讲解。Google Maps API的各种功能,比如创建地图、添加标记、绘制线路、设置信息窗口等等,都被作者一一剖析,并且提供了大量的代码片段。更重要的是,作者还讲解了如何处理API的各种事件和回调函数,这对于实现复杂的地图交互至关重要。我曾经遇到过一些API调用的难题,通过查阅这本书,很快就找到了解决方案。

评分

总而言之,这是一本真正能够解决实际问题的技术书籍。它不仅在内容上详实,在讲解方式上也独树一帜。我非常庆幸能够读到这样一本高质量的书籍,它为我的Rails和Google Maps开发之路奠定了坚实的基础,并且给了我继续探索的信心和动力。

评分

我非常欣赏作者在讲解过程中所展现出的耐心和细致。每一步操作都经过反复推敲,力求让读者能够清晰地理解。书中还包含了许多“最佳实践”和“技巧分享”,这些都是在实际开发中非常宝贵的经验。例如,关于如何优化地图性能、如何处理大量的标记点、如何实现用户自定义的地图样式等等,这些内容在其他书中很少见到。

评分

在Ajax的应用方面,这本书也展现出了其独到之处。作者详细讲解了Ajax的核心原理,包括XMLHttpRequest对象的使用、数据异步加载的方式等等。更重要的是,书中将Ajax与Rails和Google Maps紧密结合,展示了如何通过Ajax实现地图的动态更新、标记点的实时添加和删除,以及用户交互的流畅体验。我曾经尝试过用纯JavaScript实现这些功能,但过程异常繁琐,而通过这本书学习到的Ajax技巧,让整个过程变得简单高效,极大地提升了开发效率。

评分

我强烈推荐这本书给任何想要深入了解Google Maps和Rails开发的开发者。无论你是初学者还是有一定经验的开发者,都能从中获益良多。这本书不仅能够帮助你掌握技术,更能培养你解决问题的能力和独立思考的习惯。

评分

这本书的装帧设计给我留下了深刻的印象,封面使用了简洁明了的蓝色和白色作为主色调,配合着Google Maps标志性的地图图标,一眼就能看出其主题。书脊处的字体清晰易读,即使放在高低错落的书架上也能轻易找到。翻开书页,纸张的质感相当不错,厚实而有韧性,不会轻易出现褶皱,而且字迹印刷清晰,墨色均匀,即使长时间阅读也不会让眼睛感到疲劳。

评分

从开发者的角度来看,这本书无疑是非常优秀的。它能够帮助开发者快速掌握Rails和Google Maps的开发技巧,并且能够独立完成一些复杂的地图应用。书中的项目示例也足够丰富,涵盖了从简单的地图展示到复杂的地理信息查询等多种场景,为我提供了大量的灵感和参考。

评分

我最喜欢的部分是关于Geocoding和Reverse Geocoding的章节。作者用非常直观的方式解释了如何将地理位置信息(如地址)转换为经纬度坐标,以及如何将经纬度坐标转换回可读的地址。书中提供的代码示例非常实用,我直接应用到了我的项目中,效果出乎意料的好。这让我对地理信息系统有了更深的理解,也认识到在Web开发中处理地理数据的重要性。

评分

这本书不仅仅是一本技术手册,更像是一位经验丰富的导师在指导我学习。作者的语言风格幽默风趣,阅读起来一点也不枯燥。他会用一些生动的比喻来解释抽象的概念,让我能够更容易地理解。而且,书中还穿插了一些“小故事”和“思考题”,引导我主动去探索和学习,这让我受益匪浅。
