1、当通过showModalDialog('CustomerSelected.aspx','subpage','dialogWidth:500px;dialogHeight:380px;center:yes;help:no;resizable:no;status:no'); //打开模态子窗体,并获取返回值。
传值时，需要将字符串里面的单引号替换掉 ss.replace("'","´");页面显示时将其替换回来即可
document.getElementById("txtSendPerson").value=result.split("'")[1].replace("´","'");
2、DropDownList 清空方法
答1：

3、aspx网页中插入flash文件代码
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="255" height="53">
