Javascript Delete Row Problem

Asked by johnny_32 in Document Object Model, JavaScript

I have a dynamic table with tr ids set as below as an example.
<Table name = "tblGrid">
<tr id=1>
<Td></td>
</tr>
<tr id=2>
<Td></td>
</tr>
<tr id=3>
<Td></td>
</tr>
<tr id=4>
<Td></td>
</tr>
</table>

I then have a array which determines which row ids need deleting eg (1,2,3)

In order to do this i loop through the table rows. If the table row matches the array item to be deleted it is deleted. The problem is the table rows go out of synch once it is deleted.

For example :
Looping through array(1,2,3)
Array item 1

TR 1 ArrayItem(1) TR1 equals ArrayItem(1) so delete Row 1
TR 2
TR 3
TR 4

Array item 2 I want to delete TR(2) but the loop now counts to TR3 as this is the 2nd item in the loop

TR 2
TR 3
TR 4

             In example here table has 4 TRs as above 
 
 
var flr = document.getElementById('tblGrid');
                var  count = flr.rows.length;
                            for (var i = 0; i < count; i++) {
                  
                                for (iTem = 0; iTem < loopIds.length; iTem++) {
 
                                    if (i > 0 ) { // dont want table header row
                                             if (loopIds[iTem] == i) {
                                            var flr2 = document.getElementById('tblGrid');
                                            IDval = parseInt(flr.rows[i].id, 0);
                                                                              
                                            document.all.tblGrid.deleteRow(IDval);
                                         }
                                     }
                                 }
                                
                                
                         }
