javascript - Angular ui-router - how to access parameters in nested, named view, passed from the parent template?

Question

Hi I am trying to access a parameter in the controller "ViewWorklogCrtl" while using ui-router and running into difficulty.

Basically, my parent template contains:

a(ui-sref="instance-ticket.worklog({id:{{ticket.testnum}}})") show

and then further down the page:

section(ui-view="top-section")

Then in my app.js, containing client-side routing info in short I have:

 $stateProvider
.state('instance-ticket', {
  url: '/ticket/:instanceID',
  templateUrl: 'partials/instance-ticket',
  controller: 'ViewTicketCrtl'
})
.state('instance-ticket.worklog', {
  views:{
    'top-section':{
      templateUrl:'/partials/ticket.worklog.jade',
      controller: 'ViewWorklogCrtl'
      }
  }
  })

The template loading is working correctly, the issue and question I can't find an answer to is - how to access "testnum" being passed through the ui-sref link, to and within the ViewWorkLogCtrl... Is there a better approach to this?

Much thanks!!!

Answer 1

The instanceID is declared as an parameter, so we can access it like this

.controller('ViewWorklogCrtl',
    [       '$scope','$stateParams'
    function($scope , $stateParams ) {    
        // 
        $scope.instanceID = $stateParams.instanceID;
        ...

All the other details could be found here https://github.com/angular-ui/ui-router/wiki/URL-Routing

And the call to ui-sref should be like this

<a ui-sref="instance-ticket.worklog({ instanceID:ticket.testnum })" >..

Extend:

In case that we would like to get two parameters, 1) instanceID from the parent 2) testnum from the current, we have to adjust the state defintion like this

.state('instance-ticket', {
  url: '/ticket/:instanceID',      // instanceID
  templateUrl: 'partials/instance-ticket',
  controller: 'ViewTicketCrtl'
})
.state('instance-ticket.worklog', {
  // new param defintion
  url: '/worklog/:testnum',         // testnum
  views:{
    'top-section':{
      templateUrl:'/partials/ticket.worklog.jade',
      controller: 'ViewWorklogCrtl'
      }
  }

And the ui-sref

<a ui-sref="instance-ticket.worklog({ instanceID:1, ticket.testnum:2 })" >..

And we can access it like this:

.controller('ViewWorklogCrtl',
    [       '$scope','$stateParams'
    function($scope , $stateParams ) {    
        // 
        console.log($stateParams.instanceID)
        console.log($stateParams.testnum)
        ...
