Nodejs + jquery Mobile build a simple Mobile web (client)

The previous section demonstrates how to use nodejs and jqm to build a simple server that supports CRUD operations on applications (see node. js + jquery Mobile to build a simple Mobile web (server )), the server uses nodejs technology and the mongodb database and the lightweight web development framework expressJS. The routes use the restful style, so you can also use restify for development. Client implementation is mainly implemented through ajax calls. use the jade template engine. the client mainly contains two files: layout. jade and index. jade 1. layout. the jade layout file contains the js and css file copy Code required by the application !!! 5 html head title = 'nodejsjqm 'meta (name = 'viewport', content = 'width = device-width, initial-scale = 1 ') meta (name = 'Apple-mobile-web-app-capable', content = 'yes ') meta (name = 'Apple-mobile-web-app-status-bar-style', content = 'black') link (rel = 'stylesheet ', href = 'HTTP: // code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css') script (src = 'HTTP: // code.jquery.com/jquery-1.9.1.min.js') script (src = 'HTTP: // code. j Query.com/mobile/1.4.2/jquery.mobile-1.4.2.min.js') body! = Body copy Code 2. index. jade main interface file, the application uses multi-page design. copy the code div # index (data-role = 'page') div (data-role = 'header', data-theme = 'B') h1 NodeJs and Jqm. ui-btn-right (href = '# add', data-icon = 'gal') add div (data-role = 'content ') ul (data-role = 'listview ', data-inset = 'true', id = 'fruitslist')-for (var index = 0; index <fruits. length; index ++) {li a (href = '# fruitview', id = fruits [index]. _ id) img(src+'1.png ') h3 = fruits [index]. title p = fruits [index]. content-} div (data-role = 'footer ', data-position = 'fixed') div (data-role = 'navbar', data-theme =' B ') ul li a (href = '# Index', data-theme =' B ') Home li a (href =' # ', data-theme =' B ') blog li a (href = '#', data-theme = 'B') Email copy code B. view page, used to view the specified object copy code div # fruitview (data-role = 'page') div (data-role = 'head', data-theme = 'B ') a (data-rel = 'back', data-icon = 'back', data-derection = 'reverse') back h1 fruit view div (data-role = 'content ') div (data-role = 'filedin in') label (for = 'ftitle') Title: h1 # ftitle div (data-role = 'filedin in ') label (for = 'fdesc') Desc: p # fdesc div. ui-bar (data-role = 'footer ', data-theme =' B ', data-position = 'fixed') div (data-role = 'controlgroup ', data-type = 'horizontal ') a (href =' # editfruit ', data-icon = 'gear', data-transition = 'flip ') edit a (href = '# confirmDialog', data-icon = 'delete', data-rel = 'Dialog ') delete copy code c. add new object page copy code div # add (data-role = 'page') div (data-role = 'header', data-theme = 'B ') a (data-rel = 'back', data-icon = 'back', data-derection = 'reverse') back h1 Add fruit a (href = '# add ', data-icon = 'pload') Add div (data-role = 'content') div (data-role = 'filedcontainer') label (for = 'fruit-title ') title input (type = 'text', value = '', id = 'fruit-title', name = 'fruit-title') div (data-role = 'filedin in ') label (for = 'fruit-content') content input (type = 'text', value = '', id = 'fruit-content', name = 'fruit-content ') div (data-role = 'footer ', data-position = 'fixed', data-theme =' B ') a # save-btn (href = '#', data-icon = 'check') Save copy code d. request data through ajax, listen to the beforepageshow event on the page, and process data initialization when the specified page is loaded.
