    <p>This is related to a question I asked previously here: <a href="https://stackoverflow.com/questions/7354760/how-to-implement-chained-method-calls-like-jquery">How to implement chained method calls like jQuery?</a></p> <p>I have been using the method from the check answer from some time there, and it works well. But I would like to alter the syntax for my toolkit even further.</p> <ol> <li><p><code>foo(firstarg).bar(secondarg); // should function as the question above.</code></p></li> <li><p><code>foo(onlyarg).bar // a function with one argument</code></p></li> <li><p><code>foo.bar(onlyarg); // should also work, when a first argument is not appropriate.</code></p></li> <li><p><code>foo.bar; // a function without an argument, or returns a static value.</code></p></li> </ol> <p>I would like all 4 syntaxs to work off the same foo object, but lack the OOP understanding to do so. I have tried a few things, and so far I can get 1 &amp; 2 to work, and 3 &amp; 4 to work, but not to all work together. It also would be nice if chaining remained an option by having each function return the root object.</p> <p>Edit: I clearly need to be more specific, here is what I have now:</p> <pre><code> var main = function(obj){ this.obj = obj; }; var tool = function(obj){ return new main(obj); }; main.prototype = { alertThisPlus : function(plus){ alert(this.obj + ' ' + plus); }, alertJustThis : function(){ return alert(this.obj); } }; </code></pre> <p>usage</p> <pre><code> tool('hello').alertThisPlus('world'); // returns alert('hello world') tool().alertJustThis('hello world'); // returns alert('hello world'); </code></pre> <p>what I would like is to do this:</p> <pre><code> tool('hello').alertThisPlus('world'); // returns alert('hello world') no change tool.alertJustThis('hello world'); // returns alert('hello world') does not work </code></pre>

    1. COThis really isn't OOP... but mute point. 3 and 4 are incompatable unless `bar` is a function. The best you can do to make them compatable is to call `bar` with no arguments. Likewise with 1 and 2.

    2. COright. I have 1&2 working already, and I have 3&4 working already. Its getting all working at once. I know its possible because of jquery: both $(arg).foo works, as well as $.browser for instance.

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).
