    spUtil - recordWatch(Object $scope, String table, String filter, Function callback)

    Watches for updates to a table or filter and returns the value from the callback function.

    Allows a widget developer to respond to table updates in real-time. For instance, by using recordWatch(), the Simple List widget can listen for changes to its data table. If records are added, removed, or updated, the widget updates automatically.

    주:
    When passing the $scope argument into the recordWatch() function, inject $scope into the parameters of your client script function.
    표 25. Parameters
    Name Type Description
    $scope Object Scope of the data object updated by the callback function.
    table String Watched table.
    filter String Filter for fields to watch.
    callback Function Optional. Parameter to define the callback function.
    표 26. Returns
    Type Description
    Promise Return value of the callback function. 
    //A simple recordWatch function.
spUtil.recordWatch($scope, "live_profile", "sys_id=" + liveProfileId);

//In a widget client script
function(spUtil, $scope) {
  /* widget controller */
  var c =this;

  // Registers a listener on the incident table with the filter active=true, 
  // meaning that whenever something changes on that table with that filter, 
  // the callback function is executed.    
  // The callback function takes a single parameter 'response', which contains 
  // the property 'data'. The 'data' property contains information about the changed record. 
  spUtil.recordWatch($scope, "incident", "active=true", function(response) {
        
    // Returns the data inserted or updated on the table 
    console.log(response.data);   
    
    });
}

    spUtil - refresh(Object $scope)

    Calls the server and replaces the current options and data with the server response.

    Calling spUtil.refresh() is similar to calling server.refresh(). However, when you call spUtil.refresh(), you can define the $scope object.

    표 27. Parameters
    Name Type Description
    $scope Object Scope defined for the update.
    표 28. Returns
    Type Description
    Object Updated options and data objects.

    표 36. Returns
    Type Description
    void

    spUtil - update(Object $scope)

    Updates the data object on the server within a given scope.

    This method is similar to server.update(), but includes a $scope parameter that defines the scope to pass over.

    표 37. Parameters
    Name Type Description
    $scope Object Scope defined for the update.
    표 38. Returns
    Type Description

    The following example includes a P1 widget that watches for changes to the state field and uses a filter to watch all active P1s and let the callback function determine whether to refresh the data. The data.changes property contains an array of any updated fields. If the state of any fields have changed, the data is updated in the widget.

    var q = "priority=1^active=true^EQ";
spUtil.recordWatch($scope, "incident", q, function(event, data) {
   if (data.changes.includes("state")) { // only update if state was updated.
      spUtil.update($scope);
   }
});
