WEB平台下的基于HTML5标准离线应用开发

Offline Application Development Based on the HTML5 Standard of WEB Platform

HTML5是由W3C发布的新一代HTML标准,不仅强化了Web网页的表现性能,还拥有很多API接口,开发者利用这些接口,可以便捷地创建更加丰富、引人入目的应用程序。在分析研究HT-ML5标准基础上,利用其技术实现了一个离线便签管理程序系统,既直观展示了HTML5的内容描述标签、直接支持表单验证、视频音频标签、网页元素的拖拽、工作线程等新特性,又介绍了利用DOM Storage和Web SQL Database两种存储机制进行离线应用开发的方法。文章对基于HTML5的应用开发具有一定的参考价值。

HTMLS, the new HTML standard issued by W3 C, not only strengthens the performance of the Web page but also has many API interfaces, which can easily create more application programs. Based on the analysis of the HTML5, tech- nology is used to realize the offline signature management system, directly supporting form verification, audio and video label, webpage element drag, work thread and other new features. The offline application development based on the two stor- age mechanisms of DOM Storage and Web SQL Database is introduced and explored, and the HTML5 application develop- ment discussed in this paper has a certain reference value.
