Can you change a path without reloading the controller in AngularJS

Question

It s been asked before  and from the answers it doesn t look good  I d like to ask with this sample code in consideration     My app loads the current item in the service that provides it  There are several controllers that manipulate the item data without the item being reloaded   My controllers will reload the item if it s not set yet  otherwise  it will use the currently loaded item from the service  between controllers   Problem  I would like to use different paths for each controller without reloading Item html   1  Is that possible   2  If that is not possible  is there a better approach to having a path per controller vs what I came up with here   app js  var app   angular module  myModule          config    routeProvider   function  routeProvider         routeProvider        when   items    templateUrl   partials items html     controller  ItemsCtrl          when   items  itemId foo    templateUrl   partials item html   controller  ItemFooCtrl          when   items  itemId bar    templateUrl   partials item html   controller  ItemBarCtrl          otherwise  redirectTo    items                Item html   lt  -- Menu -- gt   lt a id  fooTab  my-active-directive  view name  href    item   item id   foo  gt Foo lt  a gt   lt a id  barTab  my-active-directive  view name  href    item   item id   bar  gt Bar lt  a gt   lt  -- Content -- gt   lt div class  content  ng-include    src  view template  gt  lt  div gt    controller js     Helper function to load  scope item if refresh or directly linked function itemCtrlInit  scope   routeParams  MyService       scope item   MyService currentItem    if    scope item        MyService currentItem   MyService get  itemId   routeParams itemId         scope item   MyService currentItem        function itemFooCtrl  scope   routeParams  MyService       scope view    name   foo   template   partials itemFoo html      itemCtrlInit  scope   routeParams  MyService     function itemBarCtrl  scope   routeParams  MyService       scope view    name   bar   template   partials itemBar html      itemCtrlInit  scope   routeParams  MyService       Resolution   Status  Using search query as recommended in the accepted answer allowed me to provide different urls without reloading the main controller   app js  var app   angular module  myModule          config    routeProvider   function  routeProvider         routeProvider        when   items    templateUrl   partials items html     controller  ItemsCtrl          when   item  itemId     templateUrl   partials item html   controller  ItemCtrl  reloadOnSearch  false          otherwise  redirectTo    items                Item html   lt  -- Menu -- gt   lt dd id  fooTab  item-tab  view name  ng-click  view   views foo   gt  lt a href    item   item id    view foo  gt Foo lt  a gt  lt  dd gt   lt dd id  barTab  item-tab  view name  ng-click  view   views bar   gt  lt a href    item   item id    view foo  gt Bar lt  a gt  lt  dd gt    lt  -- Content -- gt   lt div class  content  ng-include    src  view template  gt  lt  div gt    controller js  function ItemCtrl  scope   routeParams  Appts       scope views         foo   name   foo   template   partials itemFoo html        bar   name   bar   template   partials itemBar html           scope view    scope views  routeParams view       directives js  app directive  itemTab   function      return function scope  elem  attrs        scope  watch attrs itemTab  function val          if  val  Tab     attrs id            elem addClass  active            else           elem removeClass  active                              The content inside my partials are wrapped with ng-controller

I couldn t make any of the answers here to work  As a horrible hack  I store in local storage a timestamp when I change the route  and check at page initialization whether this timestamp is set and recent  in that case I don t trigger some initialization actions  In controller  window localStorage  routeChangeWithoutReloadTimestamp     new Date   getTime     location path myURL    In config   when myURL                templateUrl   main html               controller  MainCtrl               controllerAs   vm               reloadOnSearch  false              resolve                                var routeChangeWithoutReloadTimestamp                       window localStorage  routeChangeWithoutReloadTimestamp                    var currentTimestamp   new Date   getTime                    if   routeChangeWithoutReloadTimestamp                            currentTimestamp - routeChangeWithoutReloadTimestamp  gt   5000                          initialization code here                                     reset the timestamp to trigger initialization when needed                 window localStorage  routeChangeWithoutReloadTimestamp     0                     I used a timestamp rather than a boolean  just in case the code is interrupted before having a chance to reinit the value stored before changing route  The risk of collision between tabs is very low

Though this post is old and has had an answer accepted  using reloadOnSeach false does not solve the problem for those of us who need to change actual path and not just the params   Here s a simple solution to consider   Use ng-include instead of ng-view and assign your controller in the template    lt  -- In your index html - instead of using ng-view -- gt   lt div ng-include  templateUrl  gt  lt  div gt    lt  -- In your template specified by app config -- gt   lt div ng-controller  MyController  gt   variableInMyController   lt  div gt     in config  routeProvider    when   my page route  id          templateUrl   myPage html            in top level controller with  route injected  scope templateUrl        scope  on   routeChangeSuccess  function       scope templateUrl    route current templateUrl        in controller that doesn t reload  scope  on   routeChangeSuccess  function        update your scope based on new  routeParams      Only down-side is that you cannot use resolve attribute  but that s pretty easy to get around   Also you have to manage the state of the controller  like logic based on  routeParams as the route changes within the controller as the corresponding url changes   Here s an example  http   plnkr co edit WtAOm59CFcjafMmxBVOP p preview

Here s my fuller solution which solves a few things  Vigrond and  rahilwazir missed    When search params were changed  it would prevent broadcasting a  routeUpdate  When the route is actually left unchanged   locationChangeSuccess is never triggered which causes the next route update to be prevented  If in the same digest cycle there was another update request  this time wishing to reload  the event handler would cancel that reload   app run    rootScope     route     location     timeout   function   rootScope   route   location   timeout          url    path   forEach function  method            var original    location method           var requestId   0           location method    function  param  reload                   getter             if   param  return original call  location                  only last call allowed to do things in one digest cycle             var currentRequestId     requestId              if  reload     false                    var lastRoute    route current                     intercept ONLY the next  locateChangeSuccess                 var un    rootScope  on   locationChangeSuccess   function                          un                        if  requestId     currentRequestId  return                       if   angular equals  route current params  lastRoute params                                this should always be broadcast when params change                          rootScope  broadcast   routeUpdate                                              var current    route current                       route current   lastRoute                         make a route change to the previous route work                      timeout function                             if  requestId     currentRequestId  return                           route current   current                                                                 if it didn t fire for some reason  don t intercept the next one                  timeout un                             return original call  location  param

If you need to change the path  add this after your  config in your app file    Then you can do  location path   sampleurl   false   to prevent reloading  app run    route     rootScope     location   function   route   rootScope   location        var original    location path       location path   function  path  reload            if  reload     false                var lastRoute    route current              var un    rootScope  on   locationChangeSuccess   function                       route current   lastRoute                  un                                      return original apply  location   path                 Credit goes to https   www consolelog io angularjs-change-path-without-reloading for the most elegant solution I ve found

If you don t have to use URLs like   item   item id   foo and   item   item id   bar but   item   item id    foo and   item   item id    bar instead  you can set up your route for  item   item id    to have reloadOnSearch set to false  https   docs angularjs org api ngRoute provider  routeProvider   That tells AngularJS to not reload the view if the search part of the url changes

I use this solution   angular module  reload-service module        factory  reloadService   function  route  timeout   location      return        preventReload  function  scope  navigateCallback            var lastRoute    route current            scope  on   locationChangeSuccess   function                if  lastRoute   route templateUrl      route current   route templateUrl                  var routeParams   angular copy  route current params                  route current   lastRoute                navigateCallback routeParams                                              usage  controller  noReloadController   function  scope   routeParams  reloadService          scope routeParams    routeParams        reloadService preventReload  scope  function newParams             scope routeParams   newParams                 This approach preserves back button functionality  and you always have the current routeParams in the template  unlike some other approaches I ve seen

why not just put the ng-controller one level higher     lt body ng-controller  ProjectController  gt       lt div ng-view gt  lt div gt    And don t set controller in the route    when        templateUrl   abc html       it works for me

Answers above  including the GitHub one  had some issues for my scenario and also back button or direct url change from browser was reloading the controller  which I did not like  I finally went with the following approach   1  Define a property in route definitions  called  noReload  for those routes where you don t want the controller to reload on route change    when    param1  param2   param3          templateUrl   home html       controller   HomeController       controllerAs   vm       noReload  true      2  In the run function of your module  put the logic that checks for those routes  It will prevent reload only if noReload is true and previous route controller is the same   fooRun  inject      rootScope     route     routeParams     function fooRun  rootScope   route   routeParams         rootScope  on   routeChangeStart   function  event  nextRoute  lastRoute            if  lastRoute  amp  amp  nextRoute noReload            amp  amp  lastRoute controller     nextRoute controller                var un    rootScope  on   locationChangeSuccess   function                      un                       Broadcast routeUpdate if params changed  Also update                     routeParams accordingly                 if   angular equals  route current params  lastRoute params                         lastRoute params   nextRoute params                      angular copy lastRoute params   routeParams                        rootScope  broadcast   routeUpdate   lastRoute                                        Prevent reload of controller by setting current                    route to the previous one                   route current   lastRoute                                        3  Finally  in the controller  listen to  routeUpdate event so you can do whatever you need to do when route parameters change   HomeController  inject      scope     routeParams     function HomeController  scope   routeParams                      scope  on   routeUpdate   function handler route               Do whatever you need to do with new  routeParams            You can also access the route from the parameter passed            to the event                          Keep in mind that with this approach  you don t change things in the controller and then update the path accordingly  It s the other way around  You first change the path  then listen to  routeUpdate event to change things in the controller when route parameters change   This keeps things simple and consistent as you can use the same logic both when you simply change path  but without expensive  http requests if you like  and when you completely reload the browser
