    <p>I saw this code (explicly it's in jQuery, with modification)</p> <pre><code>(function(window,undefined){ var jQuery=(function(){ var jQuery=something; jQuery.xxx=xxx; //... return jQuery; })(); //... window.jQuery=window.$=jQuery; })(window); </code></pre> <p>While I understand wrapping code in a inline function call can clearly define the variable scope, I don't understand the benefits of</p> <ol> <li>passing <code>window</code> with a parameter instead of using it directly,</li> <li>getting an instance of <code>undefined</code> by a undefined parameter, and also</li> <li>defining <code>jQuery</code> by the return value of another inline function call. Can somebody explain a bit?</li> </ol> <hr> <p><strong>EDIT</strong> write #3 more clearly:</p> <p>What I understand is that the code defines <code>jQuery</code> inside another function then return it.</p> <pre><code>//(function(window,undefined){ var jQuery=(function(){ // Inside this function defines jQuery and return it? var jQuery=function(selector,context){ return new jQuery(selector,context); //simplified }; jQuery.xxx=xxx; //... return jQuery; })(); // This executes the inline function and assign `jQuery` with the return value??? //... })(window); </code></pre> <p>This is more like the following:</p> <pre><code>function define_jQuery(){ // Inside this function defines jQuery and return it? var jQuery=function(selector,context){ return new jQuery(selector,context); //simplified }; jQuery.xxx=xxx; //... return jQuery; } //(function(window,undefined){ var jQuery=define_jQuery(); // This executes the inline function and assign `jQuery` with the return value??? //... })(window); </code></pre> <p>Wouldn't it be more simpler to do:</p> <pre><code>//(function(window,undefined){ var jQuery=function(selector,context){ return new jQuery(selector,context); //simplified }; jQuery.xxx=xxx; //... //... })(window); </code></pre>

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.
