jaymc Posted October 8, 2007 Share Posted October 8, 2007 Im trying to use javascript to delete table rows This works len = tab.rows.length; tab.deleteRow(len-1); However, it will only delete the last row of the table You can tell it to delete a row by its occurance in the table, for instance len = tab.rows.length; tab.deleteRow(3); That will delete row 3. However, once you have deleted a row, row 5 becomes row 4, rows 4 becomes row 3 etc etc, therefor telling it which specific row to delete wont work I need a way to delete a <TR> row by its ID this must work in firefox Thanks Link to comment https://forums.phpfreaks.com/topic/72286-delete-table-row/ Share on other sites More sharing options...
fenway Posted October 9, 2007 Share Posted October 9, 2007 You should be able to look up the id in the DOM and delete it. Link to comment https://forums.phpfreaks.com/topic/72286-delete-table-row/#findComment-365103 Share on other sites More sharing options...

fenway Posted October 9, 2007 Share Posted October 9, 2007 document.getElementById() to find it... then settting the display attribute to "none" should work well enough.

jaymc Posted October 10, 2007 Author Share Posted October 10, 2007 Yeh I was using that originally but the problem is there is a white space where that row has been hidden For example row 1 row 2 row 3 row 4 javascript = hide 2 row 1 row 3 row 4 What I need is this row 1 row 3 row 4 Link to comment https://forums.phpfreaks.com/topic/72286-delete-table-row/#findComment-365995 Share on other sites More sharing options...
fenway Posted October 10, 2007 Share Posted October 10, 2007 I've done this many times before, I don't get whitespace that doesn't collapse... Link to comment https://forums.phpfreaks.com/topic/72286-delete-table-row/#findComment-366226 Share on other sites More sharing options...
