It's not clear to me what you want, since your code is wrong.

Here the correct analogous:

$ref->{foo}{$bar}

(NB: autoquoting of key "foo" !)

is

demo in the JS console

>> ref={foo: {x:42}} Object { foo: {} } >> bar="x" "x" >> ref.foo[bar] 42 >> ref['foo'][bar] 42

as a side note, $ is a legal identifier in JS so you can also write

>> $ref={foo: {x:42}} Object { foo: {} } >> $ref['foo'][$bar] 42

update

demo in the Perl debugger

DB<3> $ref = {foo=> { x => 42 } } DB<4> $bar = "x" DB<5> p $ref->{foo}{$bar} 42 DB<6> p $$ref{foo}{$bar} 42

update

DB<11> use experimental 'refaliasing'; \%ref = $ref DB<12> p $ref{foo}{$bar} 42

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
