Never you can get POST data from client side (using javascript or any other client side language)
You must use a server side language to get post data (like PHP, nodeJs).
But you can simply get GET data from client side (javascript).

Following is the exact solution that you want.

Page 'A' (a.html)

   <html>
        <head>
        </head>
        <body>
            <form action="b.html" method="get" name="form1" id="form1">
                <input type="text" name="field1">
                <input type="submit" name="submit">
            </form>
        </body>
    </html>

Page 'B' (b.html)

<script>

alert(findGetParameter("field1"))

function findGetParameter(parameterName) {
    var result = null,
        tmp = [];
    location.search
        .substr(1)
        .split("&")
        .forEach(function (item) {
          tmp = item.split("=");
          if (tmp[0] === parameterName) result = decodeURIComponent(tmp[1]);
        });
    return result;
}

</script>

Can't be PHP? With PHP you can also send the info to page B and display to user all the info. In fact, is more user friendly because it's a server side process.
