Accessing Perl Array in JavaScript

Question

I have an array of unknown size in perl generated by some other perl module. Now, precisely I want to find if a value passed to a jquery function exists in the perl array or not

To check for existence, you'd want a hash. A simple way of transmitting the data would be to encode it using JSON.

% use JSON qw( );

<script type="text/javascript">

var testArray = <% JSON->new()->encode({ map { $_ => 1 } get_values() }) %>;

function checkIfValExistsInTestArray(val) {
   return testArray[val];
}

</script>

For example, if get_values() returned apple and orange, you'd get

<script type="text/javascript">

var testArray = {"apple":1,"orange":1};

function checkIfValExistsInTestArray(val) {
   return testArray[val];
}

</script>

I don't know Mason, so there could be errors, but you get the idea.
