    <p>There's already a solution for writing file JSON online but I want to save json file locally. I've tried to use this example <a href="http://jsfiddle.net/RZBbY/10/">http://jsfiddle.net/RZBbY/10/</a> It creates a link to download the file, using this call <code>a.attr('href', 'data:application/x-json;base64,' + btoa(t.val())).show();</code> Is there a way to save the file locally instead of providing a downloadable link? There are other types of conversion beyond <code>data:application/x-json;base64</code>?</p> <p>Here's my code:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;head&gt; &lt;meta charset="utf-8"&gt; &lt;title&gt;jQuery UI Sortable - Default functionality&lt;/title&gt; &lt;link rel="stylesheet" href="http://jqueryui.com/themes/base/jquery.ui.all.css"&gt; &lt;script src="http://jqueryui.com//jquery-1.7.2.js"&gt;&lt;/script&gt; &lt;script src="http://jqueryui.com/ui/jquery.ui.core.js"&gt;&lt;/script&gt; &lt;script src="http://jqueryui.com/ui/jquery.ui.widget.js"&gt;&lt;/script&gt; &lt;script src="http://jqueryui.com/ui/jquery.ui.mouse.js"&gt;&lt;/script&gt; &lt;script src="http://jqueryui.com/ui/jquery.ui.sortable.js"&gt;&lt;/script&gt; &lt;script src="http://jqueryui.com/ui/jquery.ui.accordion.js"&gt;&lt;/script&gt; &lt;link rel="stylesheet" href="http://jqueryui.com/demos/demos.css"&gt; &lt;meta charset="utf-8"&gt; &lt;style&gt;a { font: 12px Arial; color: #ac9095; }&lt;/style&gt; &lt;script type='text/javascript'&gt; $(document).ready(function() { var f = $('form'), a = $('a'), i = $('input'), t = $('textarea'); $('#salva').click(function() { var o = {}, v = t.val(); a.hide();//nasconde il contenuto i.each(function() { o[this.name] = $(this).val(); }); if (v === '') { t.val("[\n " + JSON.stringify(o) + " \n]") } else { t.val(v.substr(0, v.length - 3)); t.val(t.val() + ",\n " + JSON.stringify(o) + " \n]") } }); }); $('#esporta').bind('click', function() { a.attr('href', 'data:application/x-json;base64,' + btoa(t.val())).show(); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form&gt; &lt;label&gt;Nome&lt;/label&gt; &lt;input type="text" name="nome"&gt;&lt;br /&gt; &lt;label&gt;Cognome&lt;/label&gt; &lt;input type="text" name="cognome"&gt; &lt;button type="button" id="salva"&gt;Salva&lt;/button&gt; &lt;/form&gt; &lt;textarea rows="10" cols="60"&gt;&lt;/textarea&gt;&lt;br /&gt; &lt;button type="button" id="esporta"&gt;Esporta dati&lt;/button&gt; &lt;a href="" style="display: none"&gt;Scarica Dati&lt;/a&gt; &lt;/body&gt; &lt;/html&gt; </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.

SQuiL has stopped working due to an internal error.

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