Why the following code doesn't work?
<html>
<head>
<script type="text/javascript">
function addTable() {
var table = document.createElement('table');
table.innerHTML = "<tr><td>123</td><td>456</td></tr>";
document.getElementById("addtable").appendChild(table);
}
</script>
</head>
<body>
<input type="submit" value="New Table" onClick="addTable()"/>
<div id="addtable"></div>
</body>
</html>
createElement() method creates the HTML element specified by tagName, or an HTMLUnknownElement if tagName isn't recognized.
function generateTableHead(table, data) { let thead = table. createTHead(); let row = thead. insertRow(); for (let key of data) { let th = document. createElement("th"); let text = document.
Try: var table: HTMLTableElement = <HTMLTableElement> document. getElementById("myTable"); var row = table. insertRow(0);
To the best of my knowledge, setting the innerHTML property of a table
element or table section element (like tbody
or thead
) does not work on Internet Explorer (EDIT: I just checked - with ietester and plain IE8. Result is "unknown runtime error" for IE6 and IE8, and it crashes IE7 but that might be an IEtester specific problem).
The DOM standard way of adding rows to a table is using the insertRow()
method on a table or table section element (look for HTMLTableElement and HTMLTableSectionElement in that DOM spec) :
<script type="text/javascript">
function addTable() {
var c, r, t;
t = document.createElement('table');
r = t.insertRow(0);
c = r.insertCell(0);
c.innerHTML = 123;
c = r.insertCell(1);
c.innerHTML = 456;
document.getElementById("addtable").appendChild(t);
}
</script>
In the script, there is no explicit table section being created. AFAIK, a TBODY is automatically created, and rows are inserted in there.
EDIT: regarding IE, I should point out that you can add a table with content and all by setting the innerHTML
property, but the html you inject in there must be a complete table. So this does work, even on IE:
<script type="text/javascript">
function addTable() {
var html = "<table><tr><td>123</td><td>456</td></tr></table>";
document.getElementById("addtable").innerHTML = html;
}
</script>
