With　the　rapid　development　of　wireless　communication　technology　and　the　proliferation　of　mobile　devices,　mobile　applications　are　more　and　more　widely　used.　Depending　on　the　characteristics　that　the　existing　mobile　applications　need　long　development　cycles　depending　on　a　variety　of　mobile　devices,　this　paper　puts　forward　an　HTML5-based　mobile　middleware　on　the　basis　of　the　traditional　middleware　and　mobile　middleware.　The　mobile　middleware　uses　the　B/C/S　hybrid　architecture　and　shields　the　differences　between　the　hardware　and　software　of　mobile　devices,　which　enables　developers　to　develop　applications　that　are　suitable　for　mobile　terminal　platforms　according　to　MVC　pattern.　Compared　with　other　middlewares,　HTML5-based　mobile　middleware　has　the　advantages　of　short　develop　cycle,　low　cost　and　low　difficulty　as　well　as　good　expansibility.　©　2013　ACADEMY　PUBLISHER.
