Scroll to Top of Document After Param Change in Angular 4?

Scroll to Top of Document After Param Change in Angular 4?

I wish did fix the issue. Found the answer from an excellent response to the post How to reload the current route with the angular 2 router by @Arg0n.
My entire purpose is to scroll to the top of a product page after each param change. As it stands now, a param change does not refresh the state of the URL because the route has not changed itself. I have added the code from Arg0's response to the code above (for the routes.param listen):
code :
// reset item object based on params id change
    .subscribe(params => {
        this.id = params['id'];
        this.router.routeReuseStrategy.shouldReuseRoute = function() {
            return false;

        // get item object
            .subscribe(item => {
                this.item = item;

may help you . I need to change ng-Disabled value for one separate input which i show by ng-repeat directive. , You could allow a property 'isDisabled' to be added to your model:
code :
<li ng-repeat="lang in langs">
    <label> <input 
     <span> {{lang.name}} </span> 
  $scope.langs[0].isDisabled = true;
var app = angular.module("app", []);
app.controller('Ctrl', function ($scope) {
   $scope.isDisabled = {};
   $scope.langs = [
      { name: 'French' },
      { name: 'English' },
      { name: 'German' },
      { name: 'Chinese' },
      { name: 'Dutch' }

  <body ng-app="app" ng-controller='Ctrl as ctrl'> 
           <li ng-repeat="lang in langs">
                <span> {{lang.name}} </span> 
     <br />
     {{ ctrl.selectedLanguage }} <br />
     {{ isDisabled }}
   $scope.isDisabled[$scope.langs[0].name] = true;

should help you out As per the first final release, this is resolved.
Just pay much attention to correctly reset the state of the component when the parameter changes
code :
this.route.params.subscribe(params => {
    this.param = params['yourParam'];
    this.initialiseState(); // reset and set based on new parameter this time

it fixes the issue According to the docs, you should specify {id: '@id'} as a second parameter to $resource function. For non-GET requests this will take id parameter and place it into url string, not request body.
Here is the fiddle for that.
