jQuery默认方法  ============

inArray:  返回参数在数组中的索引,没找到是返回0。
          eg:  $.inArray("young", arr);
each:     遍历一个数组或对象属性
          eg:  $.each(obj,function(key,value){})
               当obj为数组时，key为索引值;当为对象时,key为对象属性值
extend:   用一个或多个对象扩展第一个对象
          eg:  $.extend( target, object1, [objectN] ) 
grep:     用过滤函数对数值进行过滤
          eg:  $.grep([5,6,9], function(n, i){})
          n,i分别对应值和相应位置索引
map:      对数值用相应函数重新转换
          eg:  $.map([5,6,9], function(n, i){})
          n,i分别对应值和相应位置索引
makeArray:将类似数值的对象转化为者真实的数组
          eg:  var arr = jQuery.makeArray($(".div"));
trim:     移除字符串两端的空格

HG扩展方法  ============               
----------------------------------------------------------------------------------------
chk:      检查传入的对象或值是否存在。
          return true或false
---------------------------------------------------------------
defined:  检测传入的对象或值是否定义过
          return true或false
---------------------------------------------------------------
pick:     如果传入的参数被定义返回第一个对象,否则返回第二个.
          eg: $.pick(obj, {name:"Young.Jiang"});
---------------------------------------------------------------
random:   返回介于两个值之间的整数
---------------------------------------------------------------
toInt,toFloat:    将第一个参数转化为整数或浮点数,当无法转化，返回默认值,
          para: v-需转化的值; def，默认值，未定义是为0;
---------------------------------------------------------------
gmp:      get mouse positon的缩写,获取鼠标事件的位置
          return { x:x坐标值 , y:y坐标值 }
---------------------------------------------------------------
url:      url设置
          eg: var url="http://www.holygrace.cn/index.htm?fx=drag";
          var urlpara=$.url(url); alert(urlpara.fx)  //返回"drag"; urlpara为{pageName:"index.htm",fx:"drag"}
          urlpara=$url(url,"fx"); alert(urlpara)     //相当于"drag"
          var newurl=$.url(url,"fx","dialog"); //newurl为:"http://www.holygrace.cn/index.htm?fx=dialog";
          newurl=$.url(url,{pageName:"test.aspx",fx:"star",lg:"cn"}); //newurl为:"http://www.holygrace.cn/test.aspx?fx=dialog&lg=cn";
---------------------------------------------------------------
cookie:   cookie的设置和读取
          eg: $.cookie('name', 'value');
          $.cookie('name','value',{expires: 7, path:'/', domain:'www.holygrace.cn',secure: true});
          $.cookie('the_cookie', null); //删除
