copied!<p>This is a Mootools version of what I wanted. I was actually unaware that the Mootools Hash.toQueryString() almost does this by default. It formats arrays in a way that ASP.NET MVC won't recognize so I still needed to implement my own:</p> <pre><code>var POSTEncoder = { getHash: function(request, prefix, out) { if($type(out) != 'object') { out = {}; } function add(key, value){ out[ key ] = value; }; var validPrefix = $type(prefix) == 'string'; switch($type(request)) { case 'array': if(!validPrefix) { prefix = 'request'; } request.each(function(item, i){ POSTEncoder.getHash(item, prefix + '[' + i + ']', out); }); break; case 'object': if(!validPrefix) { prefix = ''; } new Hash(request).each(function(val, key) { POSTEncoder.getHash(val, (prefix != '' ? prefix + '.' : '') + key, out); }); break; case 'string': case 'number': case 'boolean': case 'date': if(!validPrefix) { prefix = 'request'; } add(prefix, request); break; case false: add(prefix || 'request', ''); } return new Hash(out); }}; </code></pre> <p>POSTEncoder.getHash(request) will flatten out the request into key/value pairs suitable for a form POST. POSTencoder.getHash(request).toQueryString() will turn that into a query string.</p> <p>Example:</p> <pre><code>var test = { bool: true, strng: 'a', numbr: 1, basicArr: ['d','e','f'], basicObj: {x:1, y: 'z'}, objectArr: [{n:1, o:2}, {n:3,o:4}], complex: { one: 1, two: 'two', three: [{x:1},{x:2},{x:3}] }}; var hash = POSTEncoder.getHash(test); console.log(hash); console.log(hash.toQueryString()); </code></pre>
