< html >

< head >

< script type = "text/javascript" src = "jquery-1.7.1.min.js" ></ script >

< script type = "text/javascript" >

$(document).ready(function(){

     alert(100);

     var a1 = $('#a1', parent.document).val();

     var a2 = $('#a2', parent.document).val();

     alert(a1+"  "+a2);

});

</ script >

</ head >

< body >

</ body >

</ html >

 

< html >

< body >

< input type = "hidden" id = "a1" value = "123" />
