<p>I found a way to bind single elements in an array with a for loop to event handlers in jQuery.</p> <p>This guide was useful to push me in that direction:<br> <a href="http://www.foliotek.com/devblog/keep-variable-state-between-event-binding-and-execution/" rel="nofollow">http://www.foliotek.com/devblog/keep-variable-state-between-event-binding-and-execution/</a></p> <p>Now I am one level deeper and I am trying to bind muiltiple elements with the same prefix in an array to event handlers in jQuery.</p> <h2>Here's what works:</h2> <pre><code>var menu=new Array("#power","#services","#cashback","#schedule"); $(document).ready(function(){ $(function() { for(var i in menu) { (function() { var x = menu[i]; var y = menu[i]+'_menu'; $(x).hover( function () { $(x).css({ backgroundColor: "#000", color: "#3ABCEF"}); $(y).show(); }, function () { $(x).css({ backgroundColor: "#333", color: "#FFF"}); $(y).hide(); } ); $(y).hover( function () { $(x).css({ backgroundColor: "#000", color: "#3ABCEF"}); $(y).show(); }, function () { $(x).css({ backgroundColor: "#333", color: "#FFF"}); $(y).hide(); } ); })(); } }); }); </code></pre> <h2>Here's what I really want:</h2> <pre><code>var menu=new Array("#power","#services","#cashback","#schedule"); $(document).ready(function(){ $(function() { for(var i in menu) { (function() { var x = menu[i]; var y = menu[i]+'_menu'; $(x,y).hover( function () { $(x).css({ backgroundColor: "#000", color: "#3ABCEF"}); $(y).show(); }, function () { $(x).css({ backgroundColor: "#333", color: "#FFF"}); $(y).hide(); } ); })(); } }); }); </code></pre> <h2>UPDATE ::: Here is the final working implimentation:</h2> <pre><code>var menu=new Array("#power","#services","#cashback","#schedule"); $(document).ready(function(){ for(var i in menu) { (function(x, y) { $(x+','+y).hover( function () { $(x).css({ backgroundColor: "#000", color: "#3ABCEF"}); $(y).show(); }, function () { $(x).css({ backgroundColor: "#333", color: "#FFF"}); $(y).hide(); } ); })(menu[i], (menu[i] + '_menu')); } }); </code></pre>

Guidance

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.
