javascript实现简单的页面右下角提示信息框_javascript技巧

由于之前找到一个开源的很好用，可以固定在浏览器的右下角；兼容性也很好；加上之后影响到应用的一个小功能点，决定重写一个；这个只能固定在当前页面的右下加，系统是上下结构满足需求，没在继续扩展；
两个函数：
1.lay -- 设置提示框高宽（可选）
2.show -- 设置标题，内容，和停留时间

notice.js

var time;
var delayTime;
$(function(){
  // 增加浮动DIV
  $('body').append("<div id='notice' onselectstart='return false'><span class='notice_title'> </span><span class='cbtn'>[关闭]</span><div class='notice_content'></div></div>");
   
  // 更改样式
  $('#notice').css({right:"0",bottom:"0",cursor:"default",position:"fixed","background-color":"#CFDEF4",color:"#1F336B","z-index":"999",border:"1px #1F336B solid",margin:"2px",padding:"10px","font-weight":"bold","line-height":"25px",display:"none"});
  $('#notice .cbtn').css({color:"#FF0000",cursor:"pointer","padding-right":"5px",float:"right",position:"relative"});
  $('#notice .notice_content').css({margin:"3px","font-weight":"normal",border:"1px #B9C9EF solid","line-height":"20px","margin-bottom":"10px",padding:"10px"});
   
  /* 绑定事件*/
  $('#notice').hover(
    function(){
      $(this).stop(true,true).slideDown();
      clearTimeout(time);
    },
    function(){
      time = setTimeout('_notice()',delayTime);
    }
  );
   
  //绑定关闭事件
  $('.cbtn').bind('click',function(){
    $('#notice').slideUp('fast');
    clearTimeout(time);
  });
});
$.extend({
  lay:function(_width,_height){
    $('#notice').css({width:_width,height:_height});
  },
  show:function(_title,_msg,_time){
     delayTime = _time;
     $('.notice_title').html(_title);
     $('.notice_content').html(_msg);
     $('#notice').slideDown(2000);
     time = setTimeout('_notice()',delayTime);
  },
});
function _notice(){
  $('#notice').slideUp(2000);
}
