Can HTMLInput name take the values like arrays

This is an old doubt of mine which surfaced again today.

Coming from an ASP.NET background I was surprised to see this snippet

<input name='text[en]' value='aaaaaa' 开发者_开发问答/>

It was the first time I am seeing an array like value given for name

I know that this code runs.

My doubts are,

1. Is this markup valid?
2. What all values are supported for name?
3. Where can I see a W3C specification on this?

this html is not valid

please refer to w3c html spec below:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

src: section 6.2 of http://www.w3.org/TR/html401/types.html

"[" and "]" are not allowed in value of "NAME" attribute.

and, asp.net doesn't support this, though some php code can do this.

1 - Yes, it's possible.

2 - Name is type CDATA:

CDATA

Attribute values of type CDATA are made up of a sequence of characters that may include entities. Line feeds are ignored while each carriage return and tab is replaced with a space. Browsers may ignore leading and trailing whitespace within the attribute value.

CDATA attribute values are typically case-sensitive, though this is not the case with all attributes that take CDATA values.

3 - Maybe this help: http://www.w3.org/TR/html4/interact/forms.html#h-17.4

Yes is the answer but it's only the string.

You can use <input name="test[]" />

and you will receive an array of all inputs with name "test[]" in an array with name "test"
