    Just make the following changes :

    var category = $('#category').val();
var url = $('#ajax_action_search').val();

$.ajax({
  type: "POST",
  url:url,
  data: {'category': category},
  dataType: "json",
  success: function(response) {}
});

    Please check the Controller action if category (parameter name) passed from the ajax is exactly same in the controller action too

    var category = $('#category').val();
var url = $('#ajax_action_search').val();
$.ajax({
    type: 'POST',
    contentType: "application/json; charset=utf-8",
    cache: false,
    async: false,
    url: url,
    data: JSON.stringify {
        category: category
    },
    dataType: 'json',
    success: function(response) {}
});

    You need to use the parameter namespace matching your extension/plugin:

    $.ajax({
  // ...
  data: {
    'tx_myext_foo[category]': category,
  },
  // ...
});

    But you’ll also need to configure the cHash evaluation since this will lead to a HTTP request like /?tx_myext_foo[category]=X which will fail without a matching cHash.

    This can be done with the excludedParameters configuration option.

    You need to make ajaxurl with action and controller. and then pass the data in full format. 

    var ajaxUrl = '<f:uri.action action="youraction" controller="Yourcontroller" />';
var category = $('#category').val();

$.ajax({
    type: 'POST',
    url: ajaxUrl,
    data: '&tx_yourext_yourplugin[category]='+category,
    success: function(response) {
    },
});
