Angular js $ state.go，参数不起作用

Question

I have tried to implement angular js $state.go() with parameter. But the $state.go() works fine without parameter. But with parameter it didn't works. I already tried many examples but no way. I need to display the parameter in html view. my state provider is,

  $stateProvider
    .state('home', {
        url: '/',
        views: {
          'content@': {
            templateUrl: 'content.html',
            controller: 'dashCtrl'
          }
        },
    params: {
        obj: {
          value:''
        }
    }
      });   

and controller is,

     dashboard.controller('dashCtrl', function ($scope, $http, $state, $stateParams){
               $state.go('dash_home', {obj: {value:'admin'}});
});

and my div is

<div>
    <h1>welcome : {{value}} || {{obj.value}}</div>

what is the problem.?

Answer 1

You cannot use parameters directly in the HTML. You first have to add it to the scope (or virtual model if you use that), eg

$scope.obj = $state.current.params.obj

And you have to do it in the controller of the state that you are going to of course, not in those where you call $state.go

I found my mistakes. The correct code is,

  $stateProvider
    .state('home', {
        url: '/',
        views: {
          'content@': {
            templateUrl: 'content.html',
            controller: 'dashCtrl'
          }
        },
    params: {
          value:''
    }
      });

controller is,

dashboard.controller('mycontroller',function($scope, $http, $state, $stateParams){

    $scope.user=$state.params.registerData;

    $scope.redirect=function()
    {
      $state.params.registerData='mycontent';

      $state.go('dash_home', {registerData:$state.params.registerData});
    }

});

thanks all.

I guess you can't use objects in params. Just replace

params: {
    obj: {
      value:''
    }
}

to this:

params: {
      value:''
}

and also: $state.go('dash_home', {obj: {value:'admin'}}); to $state.go('home', {value:'admin'});
