    <p>I'm using an extension for jQuery "<a href="https://gist.github.com/461488" rel="noreferrer">contains</a>", shown below:</p> <pre><code>$.extend($.expr[':'],{ containsExact: function(a,i,m){ return $.trim(a.innerHTML.toLowerCase()) === m[3].toLowerCase(); }, containsExactCase: function(a,i,m){ return $.trim(a.innerHTML) === m[3]; }, containsRegex: function(a,i,m){ var regreg = /^\/((?:\\\/|[^\/])+)\/([mig]{0,3})$/, reg = regreg.exec(m[3]); return RegExp(reg[1], reg[2]).test($.trim(a.innerHTML)); } }); </code></pre> <p>I have a table with certain cells that I'm trying to format conditionally, so I'm using the extension in a <code>td</code> selector, with the <code>containsRegex</code> function. The problem that I'm running into is that many of the regular expressions that I'm trying to use (which I've tested out on javascript regex testers like <a href="http://regexpal.com/" rel="noreferrer">this</a> and they've worked) do not work with this function. These are the various strings that I'd like to match: </p> <blockquote> <p>Note that a "x" could be a x,t,f or v and an "X" could be an X,T,F or V. Lastly an "(mb)" could be any two lower case letters a-z in parenthesis.</p> <blockquote> <p>-, (mb), x*, x*(mb), x, x(mb), X*, X*(mb), X</p> </blockquote> </blockquote> <p>And here is the code with several of the regex statements that I'm using:</p> <pre><code> $("td:containsExact('-')").addClass("0 queue"); // - $("td:containsRegex('/[^xtfv*]\([a-z]{2}\)/g')").addClass("1 active"); // (mb) $("td:containsRegex('/\b[xtfv]\*(?!\()/g')").addClass("2 queue review"); // x* $("td:containsRegex('/\b[xtfv]\*(?:\([a-z]{2}\))/g')").addClass("3 active review"); // x*(mb) $("td:containsRegEx('/\b[xtfv](?![*\(])/g')").addClass("4 queue"); // x $("td:containsRegEx('/\b[xtfv](?:\([a-z]{2}\))/g')").addClass("5 active"); // x(mb) $("td:containsRegEx('/\b[XTFV]\*(?!\()/g')").addClass("6 queue review"); // X* $("td:containsRegEx('/\b[XTFV]\*(?:\([a-z]{2}\))/g')").addClass("7 active review"); // X*(mb) $("td:containsRegEx('/\b[XTFV](?![*\(])/g')").addClass("8 done"); // X </code></pre> <p>Most of these pass errors in Chrome. Does anyone have any pointers? Is the contains extension limited somehow? </p> <p>Thanks in advance for your help!</p>

    1. COFor reference: the error it passes is "Uncaught Syntax error, unrecognized expression: )/g')" on "x*" and "X*". It appropriately applies the class to "(mb)" but also applies those same classes for "x*(mb)"... The rest of the searches don't pass errors, but they also don't find matches.

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.

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