Options reference

Note: Direct configuration of the booking engine through the options has been deprecated and will be disabled in future. Instead use Booking Engine Configuration in Mews Operations. The only supported options now are configurationIds and openElements.

Option	Type	Contract	Description
configurationIds	array ofstring	required	Set of booking engine unique identifiers. You can get the unique identifier of a configuration from its details page in Mews Operations - see Where can I get Configuration ID?.
openElements	string	optional	A list of comma-separated CSS selectors of elements, which will automatically get attached to click event listeners for opening the Booking Engine Widget. The string is given as an argument to the document.querySelectorAll function, you can get more information about it here. The click event is being delegated, meaning that each element is being looked up on a website dynamically after the click happens. This way you can pass a selector to the elements that don’t exist yet during the initialization.

Javascript API reference

Javascript API calls are defined on the booking engine instance, which is created with the initialization call. This instance is returned to you as an argument of a callback function that you can pass as the second parameter to the initialization call. The following simple example shows how to use the calls to set up start and end dates, and then open the booking engine:

<!-- Example of use of an instance to call the API -->
<script>
Mews.Distributor({
    configurationIds: ['aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'],
}, function(distributor) {
   $('.booking-button').click(function() {
     var start = new Date();
     var end = new Date();
     end.setDate(start.getDate() + 2);

     distributor.setStartDate(start);
     distributor.setEndDate(end);
     distributor.open();
   });
});
</script>
