Javascript动态过滤器

Question

I'm looking for examples to make a filter (in the left sidebar) that when clicking on a filter updates the page content (Query), and if (the filter) has subcategories, it displays them down the selected filter (in the left sidebar).

I found that AJAX is used for this, but this works with XML files, and I use JSON. Can AJAX be used with JSON?

Thank you very much to anyone who can contribute something. Greetings.

JSON is definitely a valid data type for AJAX. All you have to do is specify the data-type in your call, otherwise it will default to text. For example:

$.ajax({
  type: 'GET',
  url : 'http://example.com',
  dataType : 'json',
  success : function( data ) {
    console.log(data);
  }
});
