# Guided Tours- Client

The Guided Tours API provides methods for launching and stopping guided tours.

This API includes methods used in [Guided Tour Designer](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/api-reference/rest-api-explorer/r_RESTAPIHTTPResponseCodes.md).

**Parent Topic:**[Client API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/api-reference/api-client.md)

## Guided Tours - applyListFilter\(Function filter\_func\)

Sets a function to retrieve filtered tour results when the `getAllTours()` method is called.

Complete signature includes `top.NOW.guided_tours.api` preceding the method name.

|Name|Type|Description|
|----|----|-----------|
|filter\_func|Function|Filter function that takes a single `tour` object from the `tours[]` array returned from `getAllTours()` method.|

|Type|Description|
|----|-----------|
|None| |

The following example shows basic API usage.

```
//create a filter function
var filtFunction = function(tour) {
   //only return those tours whose name starts with 'my'
   return tour.name.indexOf('my') === 0);
}

//apply the filter 
top.NOW.guided_tours.api.applyListFilter (filtFunction);

//call the getAllTours method to observe the filtered tours
top.NOW.guided_tours.api.getAllTours (function(er, tours) {
  if(!er) {
    console.log('The filtered tours are: ');
    console.log(tours);
  }
});

```

The following example shows how to use the `options` field on the tour object to add JSON with custom tour identifiers for reading and filtering tours inside the `filter_func()` function.

```
top.NOW.guided_tours.api.applyListFilter(function(tour) {
       var options = (tour.options)? JSON.parse(tour.options): null;
       return (options && options.my_param) ? (options.my_param == my_value) : false;
});
```

## Guided Tours - endTour\(\)

Stops a currently playing tour. This method silently exits if no tours are playing.

Complete signature includes `top.NOW.guided_tours.api` preceding the method name.

|Name|Type|Description|
|----|----|-----------|
|None| | |

|Type|Description|
|----|-----------|
|Null| |

```
//create a callback function to end the tour if it starts correctly
var cbFunction = function(err) {
	if (err) {
   console.log('Error Occurred');
}
	else {
	   // tour has started so we can call endTour
	   top.NOW.guided_tours.api.endTour();
}
}

//calling the startTour method so that we can end the tour as soon as it starts
top.NOW.guided_tours.api.startTour('a297e04b732313007077edcc5ef6a780', 2, cbFunction);

```

## Guided Tours - events.off\(String event\_name, Function listener\_function\)

Removes an existing event listener.

Complete signature includes `top.NOW.guided_tours.api` preceding the method name.

   console.log('The tour has ended'); 
}

//attaching event listeners for tourStarted and tourEnded Events
top.NOW.guided_tours.events.on('tourStarted',eventListenerTourStarted);
top.NOW.guided_tours.events.on('tourEnded', eventListenerTourEnded);

…
//start a tour
top.NOW.guided_tours.api.startTour ('a297e04b732313007077edcc5ef6a780', 2, cbFunction);
//As soon as the tour starts the eventListenerTourStarted gets fired

top.NOW.guided_tours.api.endTour();
// eventListenerTourEnded gets fired

….

//removing the event listeners top.NOW.guided_tours.events.off('tourStarted',eventListenerTourStarted);
top.NOW.guided_tours.events.off('tourEnded', eventListenerTourEnded);

```

## Guided Tours - events.on\(String event\_name, Function listener\_function\)

Attaches an event listener to a guided tour event.

Complete signature includes `top.NOW.guided_tours.api` preceding the method name.

    ```
{tour: '<tour_sys_id>'}
    ```


 JSON parameters:

-   tour\_sys\_id: String. Guided tour ID from the Guided Tours \[sys\_embedded\_tour\_guide\] table
-   step\_num: Number. Value between 0 \(first step\) and `n` \(final step\)

</table>The following example shows basic API usage.

```
//create a callback function to handle the result of the api call
var eventListenerTourStarted = function() {
   console.log('The tour has started'); 
}
var eventListenerTourEnded = function() {
   console.log('The tour has ended'); 
}

//attaching event listeners for tourStarted and tourEnded Events
top.NOW.guided_tours.events.on('tourStarted',eventListenerTourStarted);
top.NOW.guided_tours.events.on('tourEnded', eventListenerTourEnded);

…
//start a tour
top.NOW.guided_tours.api.startTour ('a297e04b732313007077edcc5ef6a780', 2, cbFunction);
//As soon as the tour starts the eventListenerTourStarted gets fired

top.NOW.guided_tours.api.endTour();
// eventListenerTourEnded gets fired

….

//removing the event listeners top.NOW.guided_tours.events.off('tourStarted',eventListenerTourStarted);
top.NOW.guided_tours.events.off('tourEnded', eventListenerTourEnded);

```

The following example shows how to use the `listener_function` parameter with `obj` as an argument.

```
top.NOW.guided_tours.events.on("tourStarted", function (obj){console.log(obj);});
```

## Guided Tours - getAllTours\(Function cb\_function\)

Gets a list of tours on the current page from which this method is called. Because this method is asynchronous, a callback function must be passed to determine operation success and get a list of tours.
