    <p>You can do it by using a function call to create a next context for each handler (but see below), like this:</p> <pre><code>var ratings = new Array("happy", "clean"); for(y = 0; y &lt; 2; y++) { for(x = 0; x &lt; 5; x++) { fullname = ratings[y] + '_' + x; (function(thisx, thisy) { document.getElementById(fullname).onmouseover = function() { star_rate(ratings[thisy], thisx, 1); }; document.getElementById(fullname).onmouseout = function() { star_rate(ratings[thisy], thisx, 2); }; })(x, y); } } </code></pre> <p>That works by passing <code>x</code> and <code>y</code> as parameters into a function, which then sets up the event handlers using the arguments rather than the outer loop's version of <code>x</code> and <code>y</code>. (I've also removed the function names in the event handler assignments above. Using a name in a function expression [as opposed to a function declaration] is problematic in some browsers, <a href="http://yura.thinkweb2.com/named-function-expressions/" rel="nofollow noreferrer">more here</a>. Also, you'd called them both <code>onmouseover</code>, which probably isn't what you meant to do. :-) )</p> <p>But that's not how I'd recommend doing it. It creates a new function for each element. Instead, I'd probably store the necessary information on the element itself as an attribute, and use a common function for all of this. That's what HTML5's <code>data-</code> prefix is for (and it works now, today, even though technically not valid). Something vaguely like this:</p> <pre><code>var ratings = new Array("happy", "clean"); var element; for(y = 0; y &lt; 2; y++) { for(x = 0; x &lt; 5; x++) { fullname = ratings[y] + '_' + x; element = document.getElementById(fullname); element.setAttribute('data-star-x', x); element.setAttribute('data-star-y', y); element.onmouseover = handleMouseOver; element.onmouseout = handleMouseOut; } } function handleMouseOver() { star_rate(this.getAttribute('data-star-y'), this.getAttribute('data-star-x'), 1); } function handleMouseOut() { star_rate(this.getAttribute('data-star-y'), this.getAttribute('data-star-x'), 2); } </code></pre> <p>You could even use event bubbling (since mouseover and mouseout bubble) to hook the events on the overall container rather than each element, since you're getting the data from the element. (That's sometimes called "event delegation".)</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
