看看这个示例，将两个文件保存后打开parent.aspx：parent.aspx

我的父页是这样的。function kk(){
var MyArgs = new Array();MyArgs = window.showModalDialog("webform6.aspx?parm1='fsd'&parm2='fdsa'", "", "dialogWidth:300px; dialogHeight:300px; dialogLeft:20px; dialogTop:20px; status:no; directories:yes;scrollbars:no;Resizable=no; " );
document.Form1.t.value =MyArgs[1].toString();
}
</script>
然后在按钮加上onclick="kk();"，这样来打一个子窗体，但在子窗体中按按钮就会又弹出一个新面。
子窗体是这样写的。 <SCRIPT>
function clickSave()
{var MyArgs = new Array("fsda","fa","fsaf" ); window.returnValue = MyArgs;
window.close();
}
</SCRIPT>onclick="clickSave();"
请各位帮忙
