Interpolated values does not reflect the latest values in an Angular app

hope this fix your issue This is happening because your move() is called only when a block is moved from outside the Grey area but the draw() is called for all mouse movement.
You need to update the currentBox position when it is selected and moved around.
  draw() {
    const movingBlockIndex = (this.dropzone1.indexOf(this.currentBox));
    if (movingBlockIndex > -1) {
      this.will_draw = false;
      const { width, height } = this.parentparent.nativeElement.getBoundingClientRect();
      const perc_x = this.mouse.x / width * 100;
      const perc_y = this.mouse.y / height * 100;
      // -5 to center (elem has its width set to 10%)
      // console.log('left', (perc_x - 5) + '%');
      this.left = perc_x - 5;
      this.topLeft = []
      this.topLeft.push(this.left);
      // -5 to center (elem has its height set to 10%)
      // console.log('top', (perc_y - 5) + '%');
      this.top = perc_y - 5;
      this.topLeft.push(this.top)
      this.dropzone1[movingBlockIndex].pos[0] = (perc_x - 5);
      this.dropzone1[movingBlockIndex].pos[1] = (perc_y - 5);
    }
  }

Assigning interpolated values to interpolated variables in Ruby


Tag : ruby , By : Salikh

this one helps. I had this in a method: , Look for instance_variable_get:
def create_data_arrays
  @local_result_hash.each do |job|
    @api_parameters.each do |parameter|
      instance_variable_get("@#{parameter}s") << job[parameter]
    end
  end
end

Angular extending anchor element with directive on interpolated values

wish helps you Angular doesn't compile html that is inserted using ng-bind-html.
There are third party modules you can use to do it, however you could also do the conversion in a service, controller, custom filter or httpInterceptor before data gets inserted.
function parseLinks(html) {
  // create container and append html
  var $div = $('<div>').append(html),
    $links = $div.find('a');
  // modify html  
  $links.not('[href]').attr('href', function(i, oldHref) {
    return $(this).text();
  });

  $links.not('[target]').attr('target', '_blank');
  // return innerHtml string
  return $div.html();
}

$http.get('/api/items').then(function(resp){
    var data = resp.data;
    data.forEach(function(item){
       item.abstract = parseLinks(item.abstract);
    });
    return data;
});

wish help you to fix your issue Instead of multiplying the interpolated strings, multiply the expressions and then interpolate:
{{ (Items | cartTotal | number: '.2') * estimate.discount}}

Getting multiple interpolated values during select statement change - Angular & ngFor


Tag : angular , By : beebob

To fix the issue you can do What I usually do in these situations is fetch those properties in the valueChanges observable whenever a selection is made, since you don't want to mess with the project form control value. That would be:
this.requestForm.get('project').valueChanges
  .subscribe((projectId: number) => {
    const project = this.projects.find((project) => project.id === projectId);
    * do whatever else with the values *
  });
