    <p>If the user selects a file via <code>&lt;input type="file"&gt;</code>, you can <a href="https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications" rel="noreferrer">read</a> and <a href="http://www.html5rocks.com/en/tutorials/file/dndfiles/" rel="noreferrer">process</a> that file using the <a href="https://www.w3.org/TR/FileAPI/" rel="noreferrer">File API</a>.</p> <p>Reading or writing arbitrary files is not allowed by design. It's a violation of the sandbox. From <a href="http://en.wikipedia.org/wiki/JavaScript#Security" rel="noreferrer">Wikipedia -> Javascript -> Security</a>:</p> <blockquote> <p>JavaScript and the DOM provide the potential for malicious authors to deliver scripts to run on a client computer via the web. Browser authors contain this risk using two restrictions. First, scripts run in a sandbox in which they can only perform web-related actions, not general-purpose programming tasks like <strong>creating files</strong>.</p> </blockquote> <p><strong>2016 UPDATE</strong>: Accessing the filesystem directly is possible via the <a href="https://developer.mozilla.org/en-US/docs/Web/API/File_System_API" rel="noreferrer">Filesystem API</a>, which is <a href="http://caniuse.com/#feat=filesystem" rel="noreferrer">only supported by Chrome and Opera</a> and <a href="http://www.html5rocks.com/en/tutorials/file/filesystem/" rel="noreferrer">may end up not being implemented by other browsers</a> (with the <a href="https://developer.microsoft.com/en-us/microsoft-edge/platform/status/filewriter/" rel="noreferrer">exception of Edge</a>).

    1. CODamn. This is stupid, of course. Javascript is supposedly an application-agnostic scripting language. Not every application is a web browser. I came here because I'm interested in scripting Photoshop, for instance. Even if some applications don't provide file access classes, it makes sense to standardize them for those applications where they are appropriate - a standard but optional feature, so experience from one app is transferable even if not universally applicable. What I learn in Photoshop won't be portable even to other Javascript hosts that allow file access.

    2. COJavascript the language and do whatever the hosting environment allows it to do. SpiderMonkey can do anything any other language can do. Javascript in the **Browser** is sandboxed.

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).
