    <p>I am working on making all of our JS code pass through jslint, sometimes with a lot of tweaking with the options to get legacy code pass for now on with the intention to fix it properly later.</p> <p>There is one thing that jslint complains about that I do not have a workround for. That is when using constructs like this, we get the error 'Don't make functions within a loop.'</p> <pre><code>for (prop in newObject) { // Check if we're overwriting an existing function if (typeof newObject[prop] === "function" &amp;&amp; typeof _super[prop] === "function" &amp;&amp; fnTest.test(newObject[prop])) { prototype[prop] = (function(name, func) { return function() { var result, old_super; old_super = this._super; this._super = _super[name]; result = func.apply(this, arguments); this._super = old_super; return result; }; })(prop, newObject[prop]); } } </code></pre> <p>This loop is part of a JS implementation of classical inheritance where classes that extend existing classes retain the super property of the extended class when invoking a member of the extended class. Just to clarify, the implementation above is inspired by this <a href="http://ejohn.org/blog/simple-javascript-inheritance/" rel="noreferrer">blog post</a> by John Resig.</p> <p>But we also have other instances of functions created within a loop.</p> <p>The only workaround so far is to exclude these JS files from jslint, but we would like to use jslint for code validation and syntax checking as part of our continuous integration and build workflow.</p> <p>Is there a better way to implement functionality like this or is there a way to tweak code like this through jslint?</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.
