Track changes in the Bitrix filter form?

Question

JavaScript

Good afternoon. Please help if anyone knows about this issue. The task is to display the selected filter parameters in a separate block. Filtered by ajax. That is, a person spent the slider, reduced the price, I need to insert up to so many rubles into the block. How to track the form? Thanks in advance

Answer 1

There is a js'nick in the catalog component, in which the changes of the inputs in the filter and the ajax call are tracked, so you need to subscribe to this event and draw a block with the content you need based on it.
