Answer 1

Try this on JS section:
var texts=["first text", "second text", "third text"];
var index=0;
$(function() {
$("#a").click(function() {
index > 1 ? index = 0 : index++;
$("#test").text(texts[index]);
});
});
Adjust `index > 1` to the highest array index minus one, in here we have 3 string, the highest array index was 2, that's why the `index > 1`.

Answer 2

whether the writing in the array can take from html

Answer 3

Example:
var x = document.getElementById("test');
but it doesn't appear

Answer 4

document.getElementById("test") should exist tag <div id="test"></div> in HTML. It does not appear because maybe there's no tag div, wrong id name, or maybe wrong link or no link if that code is in JS external file. That's all i know :)
