Edit content of textboxes in an array

[k]

Hi, I have a problem.

To edit the content of a text box in a form I can use the following
code:

document.getElementById('bugSteps').value = "data"

But I can't figure how to do this in a textbox that belongs to an
array. Puting [] with a number inside doesn't works.
Does anyone know how?
Thanks

What do you mean by "a textbox that belongs to an array"?
Post an example of whatever it is that you're talking about.

The textboxes that I want to add text are the next:

1. <input type="text" size="100" maxlength="125" name=bugSteps[]
value=""><br>
2. <input type="text" size="100" maxlength="125" name=bugSteps[]
value=""><br>

I think that they belong to an array which is defined by the [] that
have in the name.

Thanks

You better remove '[]' and use number to identify each element's name.
getElementById() is just for id. To get elements in a form, use:
document['name_of_your_form'].elements['name_of_your_elements'].
If you have more than one elements named 'name_of_your_elements', then
you get HTML collection which can be treated like an array.

Nope, not in Javascript. Adding square brackets to a control name
is actually a bad idea. If you want to treat the text boxes as an
array, you just need to give them identical name attributes.

<form name="myForm">
1. <input type="text" size="100" maxlength="125"
name="bugSteps" value=""><br>
2. <input type="text" size="100" maxlength="125"
name="bugSteps" value=""><br>
</form>

Then you can refer to them as in:

var sum=0;
for (i=0;i<document.myForm.bugSteps.length;i++) {
sum += +document.myForm.bugSteps[i];
}

Did you try reading the group FAQ? There is an entry that deals
specifically with [] in the name of an input.
