    <p>I've got this jquery script </p> <pre><code> $(document).ready(function() { $(function(){ $("#result").submit(function(e) { e.preventDefault(); var ele = $("#element").val(), target = $("#target").val(), context = $("#context").val(), border = $("#border").val(), margin = $("#margin").val(), padding = $("#padding").val(); console.log(ele, target, context, border, margin, padding); var DoubleMargin = parseInt(margin, 10) * 2; var DoublePadding = parseInt(padding, 10) * 2; var DoubleBorder = parseInt(border, 10) * 2; var ActualTarget = parseInt(target, 10) - parseInt(DoubleBorder, 10) - parseInt(DoubleMargin, 10) - parseInt(DoublePadding, 10) * 1; var result3 = parseInt(target, 10) - parseInt(DoubleMargin, 10) * 1; var MarginResult = parseInt(margin, 10) / parseInt(target, 10) * 100; var PaddingResult = parseInt(padding, 10) / parseInt(target, 10) * 100; var OriginalResult = parseInt(ActualTarget, 10) / parseInt(context, 10) * 100; var BorderResult = parseInt(target, 10) - parseInt(border, 10) * 1; //$(".result").append(ele + " " + result + "%"); $("&lt;p&gt;&lt;/p&gt;", { html: ele + " {&lt;br&gt;&lt;span&gt;width: " + OriginalResult + "%;" + " /* " + ActualTarget + " (originally " + target + ") / " + context + " */ " + "&lt;br&gt;border: " + border + "px; " + "&lt;br&gt;margin: " + MarginResult + "%; " + "&lt;br&gt;padding: " + PaddingResult+ "%;" + "&lt;br&gt; &lt;/span&gt;}" }).hide().appendTo("#code-results").fadeIn(); }); }); }); </code></pre> <p>But when someone doesn't enter a number at all I get NaN in the results? How do I get rid of that with this code? Also I want 0 to still be displayed as 0 is that possible with this?</p> <p>edit: actually I'd love for when someone doesn't enter a number rather than NaN I get 0 as the result, is that possible?</p>

    1. COIf you always want results, you can also prefix your number variables with `>>> 0`, which turns invalid numbers in 0. Side effect: The range of the number will be `[0, 4294967295]`.

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.
