You can call javascript function in GridView RowDataBound Event.

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)  
          {   
             if (e.Row.RowType == DataControlRowType.DataRow)    
                  {  
                e.Row.Attributes.Add("onClick", "ChangeColor('" + "GridView1','" + (e.Row.RowIndex+1).ToString() + "')");
            }
        }




    function ChangeColor(GridViewId, SelectedRowId) {
        var GridViewControl = document.getElementById(GridViewId);
        if (GridViewControl != null) {
            var GridViewRows = GridViewControl.rows;
            if (GridViewRows != null)
            {
                var SelectedRow = GridViewRows[SelectedRowId];
                //Remove Selected Row color if any
                for (var i = 1; i < GridViewRows.length; i++) {
                    var row = GridViewRows[i];
                    if (row == SelectedRow) {
                        //Apply Yellow color to selected Row
                        row.style.backgroundColor = "#ffffda";
                    }
                    else {
                        //Apply White color to rest of rows
                        row.style.backgroundColor = "#ffffff";
                    }
            }

            }
        }

    }
