running a function before sorting, paging...

[sali1982]

I have a question for you.

I am having a serverside table. I want to give a warning to user, before the action of sorting happens, that he has some unsaved changes. If he says proceed, I will do the sort, if not, I won't do it.

Is there any function I can bind to the table to triggers before each action, like sorting, paging so if it is confirmed by user continues the action?

On the Table Server Side, you usually assign a callback to call anytime something change like sorting, pagination or filters.

This function as we now from the documentation should look like this one.

$scope.getResource = function (params, paramsObj) {
  var urlApi = 'table.json?' + params;
  return $http.get(urlApi).then(function (response) {
    return {
      'rows': response.data.rows,
      'header': response.data.header,
      'pagination': response.data.pagination,
      'sortBy': response.data['sort-by'],
      'sortOrder': response.data['sort-order']
    }
  });
}

You want control the exact moment $http.get it's trigged.

$scope.getResource = function (params, paramsObj) {

  return $scope.showModalToCheckIfProceed().then(function() {
    var urlApi = 'table.json?' + params;
    return $http.get(urlApi).then(function (response) {
      return {
        'rows': response.data.rows,
        'header': response.data.header,
        'pagination': response.data.pagination,
        'sortBy': response.data['sort-by'],
        'sortOrder': response.data['sort-order']
      }
    });
  }, function () {
    console.log('Nope this time!')
 });
}

Not sure will work, but the idea is to return a Promise with your custom implementation. I'm going to make documentation about it, so see how do it.

Thanks for the question.
