Column order reversed when adding rows to a dynamic table

[dschectman]

This appears to be a feature of IE JavaScript. I am running IE 6.0
with the latest patches from Microsoft. Are there any workarounds
other than re-coding the source HTML to place all the non-visible
columns at the front?

I have a page with a dynamic table. The table has some visible columns
and some non-visible columns. The style "hide" is .hide {
display:none; }

<table id="SelectedLis t">
<tr class="columnhe ader">
<td>Value</td>
<td class="hide">Co de</td>
<td class="hide">Ty pe</td>
</tr>
</table>

When I add rows to this table, the order of the columns depends on
whether the hidden columns are at the beginning or end of the row.
Here is the resulting HTML for the table. Note how in the second case,
the order of the last two columns is reversed even though the function
adds them in order: column1, column2, column3.

<TBODY>
<TR class=columnhea der>
<TD class=hide>Code </TD>
<TD class=hide>Type </TD>
<TD class="">Value</TD></TR>
<TR>
<TD class=hide>colu mn1</TD>
<TD class=hide>colu mn2</TD>
<TD>column3</TD></TR>
<TR>
<TD>column1</TD>
<TD class=hide>colu mn3</TD>
<TD class=hide>colu mn2</TD></TR></TBODY>

addItem('Select edList');
function addItem(gridID)
{
var grid = document.getEle mentById(gridID );

// Test #1: first two columns hidden, las column visible
var row1 = grid.insertRow( grid.rows.lengt h);
for (i=0;i<3;i++)
{
cell = row1.insertCell (i);

if (i==0) cell.innerHTML = "column1"; //document.test.c ode.value;
else if (i==1) cell.innerHTML = "column2";
//document.test.c ateg.value;
else cell.innerHTML = "column3"; //document.test.v al.value;

if (i!=2) cell.className = "hide";
}

// Test #2: first column visible, last two hidden
var row2 = grid.insertRow( grid.rows.lengt h);
for (i=0;i<3;i++)
{
cell = row2.insertCell (i);

if (i==0) cell.innerHTML = "column1"; //document.test.c ode.value;
else if (i==1) cell.innerHTML = "column2";
//document.test.c ateg.value;
else cell.innerHTML = "column3"; //document.test.v al.value;

if (i!=0) cell.className = "hide";
}

//document.test.t blhtml.value = grid.innerHTML;
alert(grid.inne rHTML);
}

Yup, same result here. You can fix two ways: add the cells in one loop,
then hide them using a separate loop, or use createElement and add them
that way (see below):

<TBODY>
<TR class=columnhea der>
<TD class=hide>Code </TD>
<TD class=hide>Type </TD>
<TD class="">Value</TD></TR>
<TR>
<TD class=hide>colu mn1</TD>
<TD class=hide>colu mn2</TD>
<TD>column3</TD></TR>
<TR>
<TD>column1</TD>
<TD class=hide>colu mn3</TD>
<TD class=hide>colu mn2</TD></TR></TBODY>

addItem('Select edList');
function addItem(gridID)
{
var grid = document.getEle mentById(gridID );

// Test #1: first two columns hidden, las column visible
var row1 = grid.insertRow( grid.rows.lengt h);
for (i=0;i<3;i++)
{
cell = row1.insertCell (i);

if (i==0) cell.innerHTML = "column1"; //document.test.c ode.value;
else if (i==1) cell.innerHTML = "column2";
//document.test.c ateg.value;
else cell.innerHTML = "column3"; //document.test.v al.value;
The whole if..else bit can be replaced with:

cell.appendChil d(document.crea teTextNode("col umn" + (i+1)));


if (i!=2) cell.className = "hide";
}

// Test #2: first column visible, last two hidden
var row2 = grid.insertRow( grid.rows.lengt h);

Replace from here:
for (i=0;i<3;i++)
{
cell = row2.insertCell (i);
if (i==0) cell.innerHTML = "column1"; //document.test.c ode.value;
else if (i==1) cell.innerHTML = "column2";
//document.test.c ateg.value;
else cell.innerHTML = "column3"; //document.test.v al.value;

if (i!=0) cell.className = "hide";
}
to here with either the following createElement solution:

for (var i=0; i<3; i++)
{
cell = document.create Element('td');
cell.appendChil d(document.crea teTextNode("col umn" + (i+1)));
row2.appendChil d(cell);
if (i!=0) cell.className = "hide";
}
Or this 2 loop solution:

for (var i=0; i<3; i++)
{
cell = row2.insertCell (i);
cell.appendChil d(document.crea teTextNode("col umn" + (i+1)));
}

for (var j=1, len=row2.length ; j<len ; ++j){
row2.cells[j].className = "hide";
}


//document.test.t blhtml.value = grid.innerHTML;
alert(grid.inne rHTML);
}

Thanks for the tip.
