    <p>It appears you want a left and right trimmed string, and a way of updating a status field for your user. These may be of interest to you:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script&gt; //option 1: just determine if the string is valid string_valid = function (str) { validity_indicator = { true:"Valid", false:"InValid", }; return validity_indicator[str.match( /\s*([^\s](:?.*[^\s])?)\s*/ ) != null]; }; // option 2: the trim and validation sort of wrapped up in one. parse_for_validity = function (str) { if ( ( result = /\s*([^\s](:?.*[^\s])?)\s*/.exec( str ) ) == null ) { return 'Incorrect'; } return result[ 1 ]; }; // then either // errmsg.innerHTML = string_valid( your_string_here ) &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;!-- and then test them out --&gt; &lt;script&gt; alert( string_valid(" ") ); // =&gt; 'Incorrect' alert( string_valid(" abc ") ); // =&gt; 'Correct' alert( parse_for_validity(" ") ); // =&gt; 'Incorrect' alert( '...' + parse_for_validity(" abc ") + '...' ); // =&gt; '...abc...' &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>With respect to the <code>/</code>, I believe you only have to concern yourself with it when you are using it within your regular expression. Having <code>/</code> in the string you are testing against is fine. If you want to test for a <code>/</code> in your regular expression, you should be able to escape it like this <code>\/</code>, as in the following expression: <code>/\//</code></p> <p>I hope this helps. I love regex! :)</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.
