because your parent page using master page the id of 'txtOpenner' is changed to 'ContentPlaceHolder3_txtOpenner' and you can't get the element by this code 因为您使用master page的父页'txtOpenner'更改为'ContentPlaceHolder3_txtOpenner' ，因此您无法通过此代码获取元素

window.opener.document.getElementById("txtOpenner").value = ID;

you should set ClientIDMode property of your TextBox to static , 您应该将TextBox的ClientIDMode属性设置为static ，

<asp:TextBox ID="txtOpenner" ClientIDMode="Static" runat="server"></asp:TextBox>

and then your code : 然后你的代码：

window.opener.document.getElementById("txtOpenner").value = ID;

will work 将工作
