    <blockquote> <p>In one of my Web Development classes we where asked to create a script that detects NE4,NE6+,IE4,IE6+</p> </blockquote> <p>Your web development class is hopelessly, laughably out of date.</p> <p>Back in the days when Netscape4 and IE4 were common browsers, it was often necessary to sniff the browser type and serve them different stylesheets and scripts, because their support for styles and DHTML features was so very different.</p> <p>These days the baseline browser, the lowest-quality one that you have to worry about, is firmly IE6. Almost no-one is using anything lower than that, because IE6 came with XP and the use of un-upgraded Win2K and Win9X boxes is vanishingly small. Certainly no-one in the universe is using IE4 or the awful Netscape 4; very few current web sites will even work on them.</p> <p>Thanks to web standards, all the other browsers you might want to target (IE7+, Firefox2+, Opera, Safari, Chrome, Konqueror) are generally close enough to intercompatibility that you will rarely need to do much browser detection. IE6 does demand some care, but generally if you use Standards Mode you can get by with a few CSS hacks (specifically, “* html”) and some capability-sniffing in scripts, rather than have to serve up completely different content for it.</p> <blockquote> <p>Now my questions is this which way is the best way to detect the users browser object detection or using the Navigator Object?</p> </blockquote> <p>Object/method detection.</p> <p>Avoid the navigator object whenever possible; it often lies for compatibility purposes, and scanning strings to try to work out browser names can easily trip up on unexpected tokens in the user-agent string.</p> <p>In the event when you need to detect IE6 specifically (which is by far the most common browser to have to detect and add workarounds for), and there's no suitable way of capability sniffing, it's better to use <a href="http://msdn.microsoft.com/en-us/library/121hztk3(VS.85).aspx" rel="noreferrer">conditional compilation</a> than navigator.userAgent processing.</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.

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).
