window.location.reload(true);

按class查询 :               $(".myclass")
按ID查询 :                 $("#myid")
定位某个元素，查找子元素 : $(".quickMenu i").bind('click', function () {
函数里获得this的子元素  :  $(this).find('i').toggleClass("ticked");

jQuery.each( [ "put", "delete" ], function( i, method ) {
  jQuery[ method ] = function( url, data, callback, type )
{
    if ( jQuery.isFunction( data ) ) {
      type = type || callback;
      callback = data;
      data = undefined;
    }

    return jQuery.ajax({
      url: url,
      type: method,
      dataType: type,
      data: data,
      success: callback
    });
  };
});

$.put('http://stackoverflow.com/posts/22786755/edit', {text:'new text'}, function(result){
   console.log(result);
})
