Question

Experimenting with dynamic javascript: can I recursively dynamically include ?

Answer 1

+2 A:

<script type="text/javascript">
            document.write("     <script type=\"text\/javascript\">");
            document.write("document.write('<input type=\"button\" onclick=\"helloworld()\" />');");
            document.write("     <\/script>");
</script>

Will output

EDIT

After checking fire bug, the code below is what is produced.

<script type="text/javascript">
    document.write('<input type="button" onclick="helloworld()" />');     
</script>
<input onclick="helloworld()" type="button">

That is already my first code so I want to know if I can iterate the same process anyhow (it may seem stupid but I like to push the enveloppe to see how the language behaves at extreme).

"second conversion doesn't work:... Is it possible to correct the second code so that it can work ?" - If you run my code you will see that it works. Your code had problems with nesting and and double escapes(\\").

+2 A:

How about:

      ..
      <form action='#'>
      </form>

      <script type="text/javascript">
        window.addEventListener('load', function() {
          var inp = document.createElement('input');
          inp.setAttribute('type', 'button');
          input.addEventListener('click', function() {
            ..
          }, false);

          document.forms[0].appendChild(inp);
        }, false);
      </script>

Sure, it's longer, but it's efficient and it's the "proper" way to do it (outside of using jQuery).

    </body>
  </html>

Thank you very much for this very usefull source code I will study later on. I'm not saying that document.write is the way to go, I just want to experiment by myself all the ways I could do and do something stupid somehow but as I said below I like to test extreme cases to see how languages will cope with.
