如果您注意到您的 Javascript 代码存在语法错误，那么您的代码将运行良好。您缺少一个结束 } 来定义您的函数。如果没有它，您将收到意外的输入结束错误。 此外，在实际提交表单之前，您不会打开新选项卡。

这段代码可以工作:

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
    <script>
        function SetTarget() {
            document.forms[0].target = "_blank";
            console.log("Foo");
            document.forms[0].submit();

        }
    </script>
    <asp:UpdatePanel runat="server">
        <ContentTemplate>
            <asp:Button ID="btnAssign" runat="server" Text="Assign" OnClientClick="SetTarget();" />
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>
