jquery自带的resize事件只能监听文档窗口改变大小，这个插件可以对任意标签进行监听。

$("#content2").resize(function(){
      changeIfranme();
});

$(window.parent.document).find("#content-iframe").load(function(){
    var main = $(window.parent.document).find("#content-iframe");
    var thisheight = $(document).height()+30;
    main.height(thisheight < 500 ? 500 : thisheight);
});

/*控制父窗口框架*/
function changeIfranme(){
    var main = $(window.parent.document).find("#content-iframe");
    var thisheight = $('.content').height()+100;
    main.height(thisheight < 500 ? 500 : thisheight);
}

根据子窗口的大小动态改变iframe大小。

<iframe src="/myjjf/home.aspx" id="content-iframe" name="content-iframe" width="980" frameborder="0" scrolling="no" marginwidth="0" marginheight="0"></iframe>
