Browser to server

Let we have widget select, which sends request to server to get similar words at entering a word into it, and displays them on screen so, as if each of them is in document between tags <option></option>. We specify attribute portion of tag select for such behaviours of it, this attribute indicates to server how much words should be sent.

<select src= name=a portion=50></select>

Entering of each new letter, deleting of letter or changing letter (if pause, equal time of double-click by mouse, occurred after that) forces to send following request

<a cmd=rough text=word>

<a cmd=up>

<a cmd=down>

Server to browser

Server sends the following as answer to that (attributes "parent" and "after" for first tag option, got from server, is unnecessary - browser ignores them).

<option id=1>word1<option>
<option id=2>word2<option>
<option id=3>word3<option>
