<script>

  window.onload = function(){};

  //$(document).ready(function() {}); == $(function(){});

  $(document).ready(function() {

    alert("welcome to jquery");

  });

  //区别...

  //1.执行时间不同--$(document).ready()在页面框架下载完毕后执行；window.onload必须在页面全部加载完毕后执行

  //2.执行数量不同

  //3.$(document).ready()简写
