To permanently remove the row although when i click refresh, it should not be appear

I been told to add a feature where when I click those task in it will disappeared.It indicates that the task completed and do not want to see it again anymore. Besides, when refresh, everything cannot reset back.

strWhere = "Where acti='"& replace(strActi,"'","''") & "'"
    strSQL = " select acti from task "
    objRS.Open strSQL, objConn

I have made a feature to disappear the row, but after refresh everthing is back to usual.

function taskOnclick(row) {
     row.closest('tr').remove(); 
     <%=objRS("acti")%> = '0'

};

So i added a new column called acti and then when click acti will become 0 ,then show that time filter acti=1 but in coding, i cannot handle it. May i know which part i miss it? I sure here might be someone can help in this.Thanks in advance.

<tr id="taskid">
        <%
            Response.Write "<td onclick=""taskOnclick(this)""><a href=""#"">" & objRS("TASK") & "<span>"&objRS("REMK")&"</span></a></td>"
            Response.write "<td>" & objRS("DDAT") & "</td>"
            Response.write "<td class=""days"" style=""text-align:center"">" & objRS("DAYS") & "</td>"
            Response.write "<td >" & objRS("CDAT") & "</td>"


        %>
        </tr>
