How to build a table with JavaScript to display decimal, binary, octal, and hexadecimal numbers.
For (var i=0; i <=<?php echo $num ?> ; i++){
......................
}
document.write ....
The variable $num is obtained via a form's post
Expected result
_________________________________________
Decimal | Hex | Octal | Binário
0 | 0 | 0 | 0
1 | 1 | 1 | 1
2 | 2 | 2 | 10
and so on.
The toString () method is available on all versions of all browsers and accepts a base parameter.
If we set this base parameter between 2 and 16, we can convert numbers to the equivalents in string in the different numeric bases.
var content = ""
for (var i = 0; i <= 5 ; i++) {
content += "<TR>"
content += "<TD>" + i.toString(10) + "</TD>"
content += "<TD>" + i.toString(16) + "</TD>"
content += "<TD>" + i.toString(8) + "</TD>"
content += "<TD>" + i.toString(2) + "</TD></TR>"
}
document.write("<table><th>Decimal</th><th>Hexadecimal</th><th>Octal</th><th>Binário</th></tr>"+content+"</table>")You should replace in the above code
for (var i = 0; i <= 5 ; i++) {by
For (var i=0; i <=<?php echo $num ?> ; i++){
