htm file doesn't loaded with query string

I'm trying to get a query string from htm file. But when I'm writing a "?param=1" in the end of the .htm url - the file not loaded and I don't see anything in this page - The error I get is: "Incorrect document syntax". When I'm opened this url without the query string in the end, its opened normally.

This is my htm file:

<html>
<head>
    <title>Test Url sender</title>
    <meta charset="utf-8">
</head>
<body>
    <script src="file.js" type="text/javascript"></script>
    <style type="text/css">
        body {
            font-size: 12px;
            margin: 0px 10px;
        }
    </style>
    <script type="text/javascript">
        window.onload = getQueryString();

        function getQueryString() {
var queryString = window.location.search.replace(new RegExp("^(?:.*[&\\?]" + escape("param").replace(/[\.\+\*]/g, "\\$&") + "(?:\\=([^&]*))?)?.*$", "i"), "$1");
            SendUrlsToServer(queryString);
        }

    </script>
        <p>
            test paragraph
        </p>
    </body>
    </html>

(The function SendUrlsToServer its from another js file). I need to get a query string in this url.. This htm file is web resource in crm. Any help how can I solve this? Thanks.

Solution

In CRM, a webpage (HTML) or Silverlight web resource page can only accept a single custom parameter called data. anything else will cause problem.
