A router/controller for jquery mobile. Also adds support for client-side parameters in the hash part of the url. The routes handles regexp based routes. This plugin can be used alone or (better) with Backbone.js or Spine.js, because it's originally meant to replace their router with something integrated with jQM.

================================================================================ jquerymobile-router ================================================================================ jQuery Mobile router is a plugin for jQuery Mobile to enhance the framework with a client side router/controller that works with jQuery Mobile events (pagebeforecreate, pagecreate, pagebeforeshow, pageshow, pagebeforehide, pagehide). In addition, it extends jQM with a client-side parameters in the hash part of the url (yay!!!) The jQuery Mobile router javascript file must be loaded before jQuery Mobile. This plugin can be used alone or (better) with Backbone.js or Spine.js, because it's originally meant to replace their router with something integrated with jQM. ===================== What's new in the latest versions ===================== * Added a nice getParams() function to actually 'parse' parameters in the hash and get a simple object to play with them. * Support for the pageinit event. * Bugfixes to support events for the first displayed page. ===================== Upgrade notes ===================== 0.3 to 0.4 The main javascript file has been renamed to jquery.mobile.router.js 0.2 to 0.3 There's no need to use the data-params="true" anymore in your anchors since hash params are enabled by default. The reuseQueriedAjaxPages extension was removed since it wasn't so useful and a similar behaviour can be achieved with the new jquery mobile caching mechanism (but if you need it please mail me). ===================== The router/controller ===================== Whenever jQuery Mobile changes the url (usually the fragment part) the router checks if that particular url matches one of your routes and calls the handler you've provided with a bunch of useful arguments. When you define a route, you'll provide: * a regular expression to test the url/hash against * an handler (a function) * when your handler must be called (for example, you may decide to setup a route only when the pagecreate and pagebeforeshow jQM events are dispatched) The plugin exports a class in $.mobile.Router and you can instantiate your routers with the following arguments: var approuter=new $.mobile.Router(myRoutes, myHandlers, options); * myRoutes is an object defining your routes * myHandlers is an object with your function handlers * options is an object with a certain configuration (see below) --------------- myRoutes object --------------- myRoutes supports the following formats: * this one binds a certain route to the pagebeforeshow event and calls the handler, which can be an inline function or a function name (a string) that must be defined in the myHandlers object { "regularExpression": "handlerName", /* or */ "regularExpression": function(){ // your inline function here ... } /* or */ "regularExpression": someobject.functionReference } * this is the full syntax to specify various jQM events you want your route to be bound to. The object defines an "handler" property with a string value: this is the name of a function defined in the myHandlers object. Again, you may also put an inline function in the "handler" property instead of a string. The object also defines an "events" property with a string value: this is a list of (shortened) jQM events, separated by a ",". Your route will be called only when these events are fired. { "regularExpression": { handler: "handlerName", events: "bc,c,bs,s,bh,h" }, /* or */ "regularExpression": { handler: function(){ ... }, events: "bc,c,bs,s,bh,h" }, } Please refer to the following schema to understand event codes (it's really straightforward) bc => pagebeforecreate c => pagecreate i => pageinit bs => pagebeforeshow s => pageshow bh => pagebeforehide h => pagehide This is an example of a common myRoutes object: { "#localpage(?:[?/](.*))?": { handler: "localpage", events: "bs,bh" }, "ajaxPage.html(?:[?](.*))?": { handler: "ajaxPage", events: "c,bs" } } ----------------- myHandlers object ----------------- There isn't much to say about this object. Simply provide the function handlers you've specified in the myRoutes object. For example: { handlerName: function(eventType,matchObj,ui,page){ // your code here } } Your handlers will be called with the following arguments: * eventType: the name of the jQM event that's triggering the handler (pagebeforeshow, pagecreate, pagehide, etc) * matchObj: the handler is called when your regular expression matches the current url or fragment. This is the match object of the regular expression. If the regular expression uses groups, they will be available in this object. Cool eh? * ui: this is the second argument provided by the jQuery Mobile event. Usually holds the reference to either the next page (nextPage) or previous page (prevPage). More information here: http://jquerymobile.com/demos/1.0b1/docs/api/events.html * page: the dom element that originated the jquery mobile page event -------------- Public methods -------------- Router objects have the following public methods: add(myRoutes,myHandlers): You can dynamically add routes on an already instantiated router. The myRoutes and myHandlers objects were already described above. destroy(): Unbind events and deactivate this router instance getParams(hashPartOfTheUrl): Returns an object with the parameters encoded in the url or null if nothing's found. For instance, if you have something like: #detail?id=3&foo=bar and call routerInstance.getParams("?id=3&foo=bar") you'll get: { id: "3", foor: "bar" } There's an example under examples/backbone-example ! ============== jQM Configuration ============== jQuery Mobile Router supports the following parameters: ajaxApp: tells the plugin to use the full page path for its matches instead of the hash part of the url You can pass an object with the above properties to the single router instance or set it globally with this code (must be used BEFORE loading jquery.mobile.router.js): $(document).bind("mobileinit",function(){ $.mobile.jqmRouter={ ajaxApp: true }; }); ============== Notes on jQM router ============== Have you ever wanted client-side parameters in the hash part of the url in jQuery Mobile? Well, jquery mobile router automatically enables this feature for you, using an official "hack"* provided in the jQM documentation. * This hack isn't quite different from the one previously used by this plugin. But since there's something 'official', we'll be guaranteed that our code will be supported in future releases and I'm extremely happy about this. For bugs, comments, patches and requests mail me!
