On the page there are 2 sets of checkboxes and a div, into which filtered data should fall through the AJAX. There is a button with a handler in which value arrays are formed from each checkbox set and, in theory, ajax should be transferred to a php file to retrieve a dataset from a database. Now the problem is ...
While I did not include ajax lines in the handler, everything worked fine - the button worked, value arrays were formed normally and correctly. As soon as he inserted the lines with the Ajax, the button stopped working, and in the 1st checkbox set the tree of elements was completely lost.
What could it be and where was I wrong?
