How to send the value of the clicked one from several inputs with the same name?

Question

MODX

Situation: I put a language switch on the site like this:

<input src="http://nla.selective.kz/image/en.png" alt="Select language" title="Select language" name="yams_new_lang" class="yams_lang_en" xml:lang="en" dir="ltr" value="en" lang="en" type="image">
<input src="http://nla.selective.kz/image/ru.png" alt="Выберите язык" title="Выберите язык" name="yams_new_lang" class="yams_lang_ru" xml:lang="ru" dir="ltr" value="ru" lang="ru" type="image">
<input src="http://nla.selective.kz/image/kz.png" alt="Выберите язык" title="Выберите язык" name="yams_new_lang" class="yams_lang_kz" xml:lang="kz" dir="ltr" value="kz" lang="kz" type="image">

This thing works on MODX EVO, under the YAMS extension, when a button is pressed in chrome, the one that was clicked is sent, and the language switches normally, but in FF it does not switch, since it sends everything, and the site receives yams_new_lang as an empty value.
Question: How can I send the value of the clicked input from multiple inputs with the same name?

Answer 1

type="image" works like submit, so what is clicked should be sent accordingly. But of course it's better to do something differently with a link or something like that

Answer 2

according to the w3c specification, only the name-value of the button (image - the same submit) that was clicked, but not others, is sent to the server.
by the way, unselected checkbox elements are also not sent (fact for better understanding).
and yes, DO NOT set lang, because it is used at a certain localization.
