<p>
  <a href="http://benalman.com/projects/jquery-bbq-plugin/">jQuery BBQ</a> includes a powerful jQuery.deparam method that is capable of fully deserializing not only any params string that jQuery.param can create, but that PHP and Rails (and hopefully everything else) can create. And even though only the query string is being parsed this example, methods for parsing a params string out of the fragment (hash) as well parsing any stand-alone params string are included. jQuery BBQ can also be used to merge params from multiple URLs or objects into a new URL, even within element attributes. See <a href="../../docs/">the documentation</a> for a full list of methods!
</p>

<h3>Sample query strings for you to click:</h3>

<ol>
  <li>Arrays encoded like this won't work as-expected in PHP / Rails, but work in BBQ and many older server-side frameworks (jQuery 1.3.2 or older $.param, jQuery 1.4 with $.param.traditional = true):<br>
    <a href="?a=1&a=2&a=3&b=4&c=true&d=0">?a=1&a=2&a=3&b=4&c=true&d=0</a></li>
  <li>Arrays encoded like this will work as-expected in PHP / Rails / BBQ (jQuery 1.4 or newer $.param):<br>
    <a href="?a[]=1&a[]=2&a[]=3&b=4&c=true&d=0">?a[]=1&a[]=2&a[]=3&b=4&c=true&d=0</a></li>
  <li>jQuery BBQ and PHP can handle non-shallow arrays, but Rails (rack) cannot (jQuery 1.4 or newer $.param):<br>
    <a href="?a[]=0&a[1][]=1&a[1][]=2&a[2][]=3&a[2][1][]=4&a[2][1][]=5&a[2][2][]=6&a[3][b][]=7&a[3][b][1][]=8&a[3][b][1][]=9&a[3][b][2][0][c]=10&a[3][b][2][0][d]=11&a[3][b][3][0][]=12&a[3][b][4][0][0][]=13&a[3][b][5][e][f][g][]=14&a[3][b][5][e][f][g][1][]=15&a[3][b][]=16&a[]=17">?a[]=0&a[1][]=1&a[1][]=2&a[2][]=3&a[2][1][]=4&a[2][1][]=5&a[2][2][]=6&a[3][b][]=7&a[3][b][1][]=8&a[3][b][1][]=9
  &a[3][b][2][0][c]=10&a[3][b][2][0][d]=11&a[3][b][3][0][]=12&a[3][b][4][0][0][]=13&a[3][b][5][e][f][g][]=14
  &a[3][b][5][e][f][g][1][]=15&a[3][b][]=16&a[]=17</a></li>
  <li>Some simple implicitly non-string values that BBQ can optionally coerce:<br>
    <a href="?a=true&b=false&c=undefined&d=&f=1&g=2&h=hello+world">?a=true&b=false&c=undefined&d=&f=1&g=2&h=hello+world</a></li>
  <li>More nested data structures. Since the arrays are shallow, this works in Rails (rack).<br>
    <a href="?a[]=4&a[]=5&a[]=6&b[x][]=7&b[y]=8&b[z][]=9&b[z][]=0&b[z][]=true&b[z][]=false&b[z][]=undefined&b[z][]=&c=1">?a[]=4&a[]=5&a[]=6&b[x][]=7&b[y]=8&b[z][]=9&b[z][]=0&b[z][]=true&b[z][]=false&b[z][]=undefined&b[z][]=&c=1</a></li>
</ol>
