in reply to Free Nodelet freed

Great idea, thanks. The square brackets thing without code tags makes javascript pretty unusable - no way to use square brackets in javascript, so no javascript arrays.

    eval is your friend (using the word friend in its loosest form :)
    <script language="javascript"> var arr = new Array('one','two'); var lb = "\x5B"; var rb = "\x5D" var code = "alert(\"Second element is \"+arr"+lb+"1"+rb+")"; eval(code); </script>

    :)

      This might be simpler:
      // Hack around mangling of left square bracket by PerlMonks. function get_item(a, i) { return eval("a\x5Bi]"); } function set_item(a, i, v) { return eval("a\x5Bi] = v"); }
      Usage:
      var a = new Array(5); set_item(a, 2, "Hello World\n"); alert(get_item(a, 2));

      Update: Never mind. New useful escapes documented here.

    Code tags wouldn't help. CODE tags just turn [ into &#91; (among other things, of course).
