Xiaoqiang's HTML5 mobile development road (33) - jqMobi basics

1. What is jqMobi

jqMobi is a JavaScript framework developed by appMobi for HTML5 browsers and mobile devices. It is an extremely fast query selection library that supports W3C queries.

Version

jqMobi source code was originally launched in January 2012. It is based on the MIT/X11 license and is hosted on GitHub. Developers can participate and continuously improve the framework through plug-ins.

Plug-in extensible

Smaller size

Intel Acquisition

Intel February 22, 2013 Acquired HTML 5 mobile application company appMobi Html5 development tools and related employees, but did not acquire the startup. After the acquisition, jqMobi was renamed appframework. The later jqMobi is actually appframework. This move is one of Intel's actions to build its own mobile application developer tool suite. In order to provide more support for html5 and CSS3, the processor giant may consider building corresponding hardware.

2. The difference between jqMobi and jQuery

jqMobi is developed by appMobi, while jQuery is a product of jQuery Foundation. The jqMobi source code is rewritten based on the jQuery source code, but the two are different products. jqMobi is smaller, faster, and has different compatibility.

After compression, jqMobi’s files are smaller than jQuery

Fast speed

According to the data of JSPerf test , which is 3 times faster than jQuery on Android and 2.2 times faster on iOS. The tested speed is 3 to 5 times that of JqueryMobile, and the speed is similar to SenchaTouch

Compatibility

jqMobi is mainly aimed at operating systems with WebKit browsers (such as Android, iOS and the latest version Designed for BlackBerry OS), jqMobi 2.0 is compatible with IE10 (windows8 and windows phone8 platforms); while jQuery is compatible with more browsers (such as ie6).
