The use of a lot of HTML5 new features, have not encountered before, do not understand, here to record the knowledge of adding point front. In hybrid app development, it's often necessary to use caching features, such as when you enter data on a page form control, and you want to see it again the next time you exit the app, such as having the ability to save drafts in your projec

SQL statements can be more cumbersome to write, and we all miss the ORM tools in the Java language at this time. Fortunately, the development community has never lacked creative developers, and many open source Web SQL ORM tools have emerged. Persistence.js is a JavaScript framework that was originally designed to perform OR Mapping HTML Web SQL to facilitate rapid WEB SQL access by client developers. Later, with the development of the framework, it began to gradually peel back the reliance

Label:HTML5 Web Storage Use HTML5 to store the user's browsing data locally. Earlier, local storage was using cookies. But Web storage needs to be more secure and fast.
