I have an html page with a single-line javascript comment as follows:

// {"key1":"value1"}, {"key2":"value2"}, {"key3":"value3"} 
<b> Sample Text </b>

I want to retrieve all the key value pairs in the comment and place them in javascript maps. How would I parse it using js/jquery? I am terrible at regexes so any help would be appreciated. If it helps, The comment will always be only the first line in the html.

EDIT:

If it makes the job easier, I could also work with –

/* {"key1":"value1"}, {"key2":"value2"}, {"key3":"value3"} */ 
<b> Sample Text </b>

    Instead of writing the javascript to the top of the HTML, write it inside a script element like so:

    <!-- HTML -->
<head>
<script type="text/javascript">
var x = { "key1": "value1", "key2": "value2", "key3": "value3" } ;
</script>
</head>
<!-- REST OF HTML -->

    You should have access to x with your data like any other javascript object.
