  function bindResize(el)

  {

  //初始化参数

  var els = document.getElementById('menu').style;

  //鼠标的 X 和 Y 轴坐标

  x = 0;

  //邪恶的食指

  $(el).mousedown(function (e)

  {

  //按下元素后,计算当前鼠标与对象计算后的坐标

  x = e.clientX - el.offsetWidth - $("#menu").width();

  //在支持 setCapture 做些东东

  el.setCapture ? (

  //捕捉焦点

  el.setCapture(),

  el.onmousemove = function (ev)

  {

  mouseMove(ev || event);

  },

  ) : (

  //绑定事件

  $(document).bind("mousemove", mouseMove).bind("mouseup", mouseUp)

  );

  //防止默认事件发生

  e.preventDefault();

  });

  //移动事件

  function mouseMove(e)

  {

  //宇宙超级无敌运算中...

  els.width = e.clientX - x + 'px';

  }

  //停止事件

  function mouseUp()
