    <p>I have a 'class' that does this and here it is:</p> <pre><code>function QS(){ this.qs = {}; var s = location.search.replace( /^\?|#.*$/g, '' ); if( s ) { var qsParts = s.split('&amp;'); var i, nv; for (i = 0; i &lt; qsParts.length; i++) { nv = qsParts[i].split('='); this.qs[nv[0]] = nv[1]; } } } QS.prototype.add = function( name, value ) { if( arguments.length == 1 &amp;&amp; arguments[0].constructor == Object ) { this.addMany( arguments[0] ); return; } this.qs[name] = value; } QS.prototype.addMany = function( newValues ) { for( nv in newValues ) { this.qs[nv] = newValues[nv]; } } QS.prototype.remove = function( name ) { if( arguments.length == 1 &amp;&amp; arguments[0].constructor == Array ) { this.removeMany( arguments[0] ); return; } delete this.qs[name]; } QS.prototype.removeMany = function( deleteNames ) { var i; for( i = 0; i &lt; deleteNames.length; i++ ) { delete this.qs[deleteNames[i]]; } } QS.prototype.getQueryString = function() { var nv, q = []; for( nv in this.qs ) { q[q.length] = nv+'='+this.qs[nv]; } return q.join( '&amp;' ); } QS.prototype.toString = QS.prototype.getQueryString; //examples //instantiation var qs = new QS; alert( qs ); //add a sinle name/value qs.add( 'new', 'true' ); alert( qs ); //add multiple key/values qs.add( { x: 'X', y: 'Y' } ); alert( qs ); //remove single key qs.remove( 'new' ) alert( qs ); //remove multiple keys qs.remove( ['x', 'bogus'] ) alert( qs ); </code></pre> <p>I have overridden the toString method so there is no need to call QS::getQueryString, you can use QS::toString or, as I have done in the examples just rely on the object being coerced into a string. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
