WHY, oh WHY, won't my cute little js work? it consistently returns
"initial", that is, it fails to update the hidden field value. PLEASE
help a humbled, annoyed fellow programmer.
var html='<input type="hidden" name="length" value="initial"/>';
var value=1;
document.write(html);
increaseValue();
function increaseValue()
{
value++;
document.getElementsByName('length').value=value;
}
cheers

Off of my head, I would say that getElementsByName() (Are you sure there is
such a method? I have never heard about it; there are getElementById and
getElementsByTagName, but I don't know everything...) doesn't return a
single object but a collection of objects (since there can be more than one
element of the same name.
Use either ID and getElementById, or (if I am correct)
document.getElementsByName('length')[0].value

There is a method called getElementsByName (which I keep forgetting
about...). It is part of the HTMLDocument interface (implemented by the
document object) as described in the DOM HTML Specification.
doesn't return a single object but a collection of objects (since there can be more than one element of the same name.
....and it does return a collection
Use either ID and getElementById, or (if I am correct) document.getElementsByName('length')[0].value
Alternatively, if the element is the descendant of a form:
document.forms['formName'].elements['length'].value

Additionally, naming a form element 'length' is asking for trouble, since
document.forms['formName'].elements.length
is already where the number of elements is stored...

Personally, I wouldn't use "value" as the name of a javascript
variable. Just asking for trouble somewhere along the way. I'm
surprised it works. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
