十万火急,高手帮忙,有关Gridview控件HyperLink弹出指定宽度和高度页面的问题,

现在代码是
<asp:TemplateField HeaderText="Link">
                            <ItemTemplate>
                               <a href='javascript:window.open("<%# "Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=AOI-7300"%>","", "height=200, width=270" )'>AOI-7300</a> 
                               <a href='javascript:window.open("<%# "Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=AOI-7200"%>","", "height=200, width=270" )'>AOI-7200</a> 
                               <a href='javascript:window.open("<%# "Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=SPI"%>","", "height=200, width=270" )'>SPI</a> 
                                
                                <%--<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "~/Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=AOI-7300"%>' Text='AOI-7300'
                                    Target="_blank" ></asp:HyperLink>
                                <asp:HyperLink ID="HyperLink3" runat="server" NavigateUrl='<%# "~/Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=AOI-7200"%>' Text='AOI-7200'
                                    Target="_blank"></asp:HyperLink>
                                <asp:HyperLink ID="HyperLink4" runat="server" NavigateUrl='<%# "~/Defect Pareto Recent Detail.aspx?name=" + Eval("Name")+ "&type=SPI"%>' Text='SPI'
                                    Target="_blank"></asp:HyperLink>--%>
                                    
可问题是弹出窗体的同时，母页也变了，只显示一个[object]，母页的title变成'javascript:window.open("39","", "height=300, width=470" ).这是什么原因啊？
