    <p>I would suggest an alternative regex, using sub-groups to capture name and value of the parameters individually:</p> <pre><code>function getUrlParams(url) { var re = /(?:\?|&amp;(?:amp;)?)([^=&amp;#]+)(?:=?([^&amp;#]*))/g, match, params = {}, decode = function (s) {return decodeURIComponent(s.replace(/\+/g, " "));}; if (typeof url == "undefined") url = document.location.href; while (match = re.exec(url)) { params[decode(match[1])] = decode(match[2]); } return params; } var result = getUrlParams("http://maps.google.de/maps?f=q&amp;source=s_q&amp;hl=de&amp;geocode=&amp;q=Frankfurt+am+Main&amp;sll=50.106047,8.679886&amp;sspn=0.370369,0.833588&amp;ie=UTF8&amp;ll=50.116616,8.680573&amp;spn=0.35972,0.833588&amp;z=11&amp;iwloc=addr"); </code></pre> <p><code>result</code> is an object:</p> <pre> { f: "q" geocode: "" hl: "de" ie: "UTF8" iwloc: "addr" ll: "50.116616,8.680573" q: "Frankfurt am Main" sll: "50.106047,8.679886" source: "s_q" spn: "0.35972,0.833588" sspn: "0.370369,0.833588" z: "11" } </pre> <p>The regex breaks down as follows:</p> <pre> (?: # non-capturing group \?|& # "?" or "&" (?:amp;)? # (allow "&amp;amp;", for wrongly HTML-encoded URLs) ) # end non-capturing group ( # group 1 [^=&#]+ # any character except "=", "&" or "#"; at least once ) # end group 1 - this will be the parameter's name (?: # non-capturing group =? # an "=", optional ( # group 2 [^&#]* # any character except "&" or "#"; any number of times ) # end group 2 - this will be the parameter's value ) # end non-capturing group </pre>

    1. COThis is what I was hoping for. What I've never seen in JavaScript documentation is mention that the exec() method will continue to return the next result set if called more than once. Thanks again for the great tip!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
