Hi, I have php code below that is creating the html entry for the 2nd column of a table.
CODE echo("<td><a href='frmKaraokeUpdateSongGroup.php?RecKey=$fldKF_Song_LU&fldKF_Key=$fldKF_Key'>$fldKF_Group</td>\n"); I am trying to get at the $fldKF_Group using javascript. I know how to find the cell and row using the command below but I can't figure out the part at the end where I mark it in bold. var GroupCurr = document.getElementById("Table_KaraokeSchedule").rows[RowCnt].cells[1].can't figure out what to put here[color=#FF0000]; I know how to do it if there is no href in the table cell (using .innerhtml). I know how to do it if there is an input textbox in the table cell. I have some example code to find the value of the href. In the past I have used .innerhtml and used the left string or right string commands to get at the data but I prefer not to do that. Google searches with parts of the command are not finding anything. Any help would be appreciated. Thanks, John This post has been edited by bowlesj: Mar 9 2019, 09:55 AM |

I tried about 6 more things from examples I could find but had no luck. For now this is what I am forced to do. It works but I am sure there is a better way. It is strictly for my use so maybe this is all I need considering time restraints.
CODE function funcCallShellToBIAB(fldKF_Key,fldMM_Key,RowCnt) { var GroupCurr = document.getElementById("Table_KaraokeSchedule").rows[RowCnt].cells[1].innerHTML; GroupCurr = Right(GroupCurr, 5); GroupCurr = Left(GroupCurr, 1); var GroupNext = document.getElementById("Table_KaraokeSchedule").rows[RowCnt + 1].cells[1].innerHTML; GroupNext = Right(GroupNext, 5); GroupNext = Left(GroupNext, 1); window.location='frmKaraoke_ShellToBIAB.php?RecKey=' + fldKF_Key + "&fldMM_Key=" + fldMM_Key + "&GroupCurr=" + GroupCurr + "&GroupNext=" + GroupNext; } This post has been edited by bowlesj: Mar 9 2019, 11:25 AM |

CODE echo("<td><a href='frmKaraokeUpdateSongGroup.php?RecKey=$fldKF_Song_LU&fldKF_Key=$fldKF_Key'>$fldKF_Group</td>\n"); Note that the link above is lacking its </a> end tag. QUOTE I know how to find the cell and row using the command below but I can't figure out the part at the end where I mark it in bold. var GroupCurr = document.getElementById("Table_KaraokeSchedule").rows[RowCnt].cells[1].can't figure out what to put here[color=#FF0000]; The following should return the contents of the first link in the cell: CODE var GroupCurr = document.getElementById("Table_KaraokeSchedule").rows[RowCnt].cells[1].getElementsByTagName('a')[0].innerHTML; If you only want the plain link text you might also use innerText instead of innerHTML. |

Thank you Christian, now I understand this one too.
document.getElementById("Table_KaraokeSchedule").rows[MyRow].cells[6].getElementsByTagName('input')[0].checked=false; John |
