Is it possible to name the text boxes that are created automatically and how to do it?

ex:

for(i=0;i<;i++)
{
document.write('<input type="text" name=?>');
}

Is it possible to have something in place of the question mark that will help in automatically give names like matix[1], matrix[2], matrix[3] etc.

Another question is whether it is possible to declare two dimensional arrays using javascript?

Sure it is. I would advise against using document.write() though - it's on its way out. Use the innerHTML property of the element instead.

(Toggle Plain Text)

<script type="text/javascript">
function ShowTextBoxes (count)
{
    var textBoxes = document.getElementById("textboxes");
    
    var HTML = "";
    for (i = 0; i < count; i++)
    {
        HTML += '<input type="text" name="' + i + '" />\n';
    }
    
    textBoxes.innerHTML = HTML;
}
</script>

<div id="textboxes">
</div>

Even innerHTML is taking a hit from other forms of child-element specification and content. For more than minor messing around, good page design these days will require some significant study of (X)HTML, CSS, and the DOM in general.

Yeah... sucks, doesn't it? :p

Yeah. Even though cross-browser support and page design is a lot easier than it was in 1999-2000, it's still (for me) a headache. Fortunately, the big scare against script seems to be undergoing a reversal; things like the Google Maps API and such require it for functionality. It at least allows one to hack recalcitrant browsers like IE. All in all, I'd rather write a C++ program to poke me in the eye with a sharp object.

Now that'd be something to see.

Thank you for the code, now I have to start working on it.
