巧妙的参数传递。

javascript代码：

 function SendDiv(id)
    {    
            
          var getid = document.getElementById(id);
          getid.style.left= window.event.x - 150;
          getid.style.top= window.event.y;
          getid.style.display='block';
//          document.getElementById("case_id").value = document.getElementById("caseid").value;
    }

页面操作代码：

 <a id="btnAccusation" href="javascript:void(null)" onclick="SendDiv('divDrag')"></a>
                                        <% if (this.UserInfo.UserType != "02")
                                           { %>
                                        <asp:LinkButton ID="lkbAccusation" runat="server" CommandName="Accusation" CommandArgument='<%#Eval("case_id")%>'
                                            Text="分派"></asp:LinkButton>
                                        <%} %>

服务器段代码：

 protected void gvMan_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "Accusation")
            {
                this.case_id.Value = e.CommandArgument.ToString();
                ScriptManager.RegisterStartupScript(this, this.GetType(), "loginipasbc", "document.getElementById('btnAccusation').click();", true);
            }
        }

页面代码（弹出DIV）：

 <div id="divDrag" cellpadding="0" cellspacing="0" oncontextmenu="return false" style="position: absolute;
           background: #9097A9; display: none; z-index: 2;  300; height: 200; border: solid #9097A9 1px; padding-top:10px; 
            cursor: move;">
               <table style="cursor: hand; background-color: #CCCCCC;">
                    <tr>
                    <td>
            <asp:TreeView ID="tvwSelect" runat="server" ExpandDepth="0" OnSelectedNodeChanged="tvw_SelectedNodeChanged"
                SelectedNodeStyle-Font-Bold="true" SelectedNodeStyle-Font-Size="13px" ShowLines="true">
            </asp:TreeView>
            </td>
            </tr>
            <tr>
            <td>
            <input onclick="GoReset('divDrag')" style="float: left; clear: left; display: block;"
                type="button" class="btn2chars" value='取消' /></td></tr>
        </div>
