Reset to default 8I suppose it would be more formally correct to use insertCell for each added cell, but just dropping in the whole string will work if you set newRow's innerHTML:
function doTheInsert() {
var newRow=document.getElementById('myTable').insertRow();
// newRow = "<td>New row text</td><td>New row 2nd cell</td>"; <-- won't work
newRow.innerHTML = "<td>New row text</td><td>New row 2nd cell</td>";
}
function doTheInsert() {
var newRow=document.getElementById('myTable').insertRow();
newRow.innerHTML="<td>New row text</td><td>New row 2nd cell</td>";
}<table id="myTable" border="1">
<tr>
<td>First row</td>
<td>First row 2nd cell</td>
</tr>
<tr>
<td>Second row</td>
<td>more stuff</td>
</tr>
</table>
<input type="button" onclick="doTheInsert()" value="Insert new row"> As per MDN, you need to add cells to the row after creating it.
function doTheInsert() {
var newRow=document.getElementById('myTable').insertRow();
// Insert a cell in the row at cell index 0
var cell1 = newRow.insertCell(0);
// Append a text node to the cell
var cell1Text = document.createTextNode('New row text')
cell1.appendChild(cell1Text);
// Insert a cell in the row at cell index 1
var cell2 = newRow.insertCell(1);
// Append a text node to the cell
var cell2Text = document.createTextNode('New row 2nd cell')
cell2.appendChild(cell2Text);
}<table id="myTable" border="1">
<tr>
<td>First row</td>
<td>First row 2nd cell</td>
</tr>
<tr>
<td>Second row</td>
<td>more stuff</td>
</tr>
</table>
<br>
<input type="button" onclick="doTheInsert()" value="Insert new row"> function doTheInsert() {
newRow="<td>New row text</td><td>New row 2nd cell</td>";
document.getElementById('myTable').innerHTML += newRow;
}
Been a while since i did normal javascript. But this should work. Probably not the nicest way to do it.
Take a look at using this instead:
<html><head>
<script>
function doTheInsert() {
var table = document.getElementById('myTable');
var newRow = table.insertRow(-1);
var newCell1 = newRow.insertCell(0);
var newCell2 = newRow.insertCell(1);
newCell1.innerHTML = "New row text";
newCell2.innerHTML = "New row 2nd Cell";
//newRow="<td>New row text</td><td>New row 2nd cell</td>";
}
</script></head>
<body>
<table id="myTable" border="1">
<tr>
<td>First row</td>
<td>First row 2nd cell</td>
</tr>
<tr>
<td>Second row</td>
<td>more stuff</td>
</tr>
</table>
<br>
<input type="button" onclick="doTheInsert()" value="Insert new row">
</body></html>
The .insertRow(-1) will append the new row to the end of the table, or use .insertRow(0) to prepend the new row to the table.
