need help on a nested Javascript table?
I've got a table for a nested function, the multiplication table. Before the nested function goes into a table it works fine... however,when it goes into the table, it comes out as table * n and not the values. Can any help on where the program is going wrong?
<html>
<head>
<title>Multiplication chart</title>
</head>
<body>
<h1> Multiplication Table </h1>
<script language="JavaScript">
<-
var n
var table
n=1
table=1
document.write('<table border="10" cellspacing="1" cellpadding="5">')
for (table=1; table<=6; table++)
{
document.write('<tr>')
for (n=1; n<=10; n++)
{
document.write('<td> (table * n) </td>')
}
document.write('</tr>')
}
document.write('</table>')
</script>
</body>
</html>

I got it. Take out the <- you don't need that.
And yes you can use document.write('<td>'+ table * n+' </td>') too.
Good Luck!

'<td> (table * n) </td>'
Note how you set the quotes, this means that it's plain text / numbers. No action will be taken on this / code writting in here will be ignored.
To fix it, you need to change it to this:
'<td>' + table*n + '</td>'
EDIT: JT whatever, is wrong. innerHTML is used to change content on the page, for a more dynamic effect.
-What you want is for the JavaScript program to create the page for you automatically - you don't want to change the content from x to y. So just ignore that tip :3
EDIT2: I forgot to tell you, in case you didn't know. In JavaScript, if you start an alert / .write or whatever, with a string, then the numbers will be converted from float to a string thus unabling direct math stuff in an alert. How to fix this:
document.write('<td>' + eval(parseFloat(table) * parseFloat(n) + '</td>')
I hope this helped!

for ( var rows = a million; rows <= n; rows++ ) { //initiate the table and the tr for ( var columns = a million; columns <= n; columns++ ) { //write the td } //end the tr and table } why yours does not artwork: a million. use are producing n*n tables, not n*n products/table cells 2. your columns additionally might desire to apply n
