I have a situation where I need to get the element in JavaScript from document.form.elementname
but the problem is that, my element name contains '.' periods in it.
So in actual its like document.form.my.stack.element
where "my.stack.element
" is the name of element. Changing the name is not in my hands and cannot be done so getElementById
is the only solution left?
Please let me know if I can still get the element using its name from the form?

One thing that you can use is the square bracket notation to access the properties of an object.
So you could use
document.form["my.stack.element"];

you can access form names by using it as an associative array. The .name is just an alternative to the associative array key example.
document.form.my.stack.element
is same as
document.form['my.stack.element']
Please note that the first snippet is an example. Of course it doesn't work because the js would treat is as an array, threatening it as document.form['my']['stack']['element']
due of punctuations.

Use: document.form['my.stack.element']
.
HTML
<form name="form">
<input name="my.stack.element">
</form>
