Accordion加载了内容以后 无法加载jquery的accordion效果

$(document).ready(function() {
  $('#accordion').accordion({
    collapsible: true,
    active: false,
    heightStyle: 'content',
    event: 'click hoverintent'
  });
  $('body').on('click', '#category a', function() {
    var page = $(this).attr('href');
    var php = $('#accordion').load('../php/' + page + '.php', function() {
      $('#accordion').accordion('destroy').accordion({
        collapsible: true,
        active: false,
        heightStyle: 'content',
        event: 'click hoverintent'
      });
    });
    return false;
  });
});
