<p>I am working on rewriting my application from YUI 2 to YUI 3.</p> <p>Sometimes I need some data from database in my JavaScript environment. Firs option is to assign some global variables in JavaScript, but global vars is not good, so I did following in YUI 2:</p> <p><strong>app.js</strong></p> <pre><code>YAHOO.namespace('MyApp'); YAHOO.MyApp = function() { var currencyRates; var userInfo; /* here a lot of code with event listeners and dom manipulations which uses currencyRates and userInfo variables */ return { initCurrencyRates: function(newRates) { currencyRates = newRates; }, initUserInfo: function(newUserInfo) { userInfo = newUserInfo; }, } }(); </code></pre> <p><strong>PHP</strong></p> <pre><code><?php $currencyRates = array('EUR' : 1.3245, 'GBP': 1.4322, 'RUB': 0.02334); //actually it comes from database print '<script>YAHOO.MyApp.initCurrencyRates(' . json_encode($currencyRates) . ')</script>'; $userInfo = array('Name' => 'Jhon', 'ID' => 10); //actually it comes from database print '<script>YAHOO.MyApp.initUserInfo(' . json_encode($userInfo) . ')</script>'; ?> </code></pre> <p>As you can see I use "public methods" YAHOO.MyApp.initUserInfo and YAHOO.MyApp.initCurrencyRates to pass data into JavaScript code.</p> <p><strong>Now I what to rewrite it using YUI 3:</strong></p> <p><strong>app.js</strong></p> <pre><code>YUI().use('node', 'event', function(Y) { var currencyRates; var userInfo; /* here a lot of code with event listeners and dom manipulations which uses currencyRates and userInfo variables */ }) </code></pre> <p><strong>PHP</strong></p> <pre><code><?php $currencyRates = array('EUR' : 1.3245, 'GBP': 1.4322, 'RUB': 0.02334); //actually it comes from database print '<script>???</script>'; ?> </code></pre> <p>How do I provide "public methods" in my YUI 3 JavaScript code? Or what is another solution to pass data inside JavaScript application code aviding global variables?</p>

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.
