问Drupal更好地公开过滤器-中止Ajax请求

EN

var filterXHR = null;
$(document).ajaxSend(function (event, jqXHR, settings) {
  filterXHR = jqXHR; // cache XHR object for current ajax request
});

// event handler for when a filter is selected/changed/etc.
$('#filters-block .form-item a').click(function () {

  // check if there is a previous request that has not yet completed
  if (filterXHR && filterXHR.readyState != 4) {
    // abort ajax request
    filterXHR.abort();

    // subsequent requests will add their own progress indicator,
    // so you probably want to remove the old one here 
    $('.ajax-progress').remove(); 
  }

  // submit exposed form, do other stuff, etc.. 
});
