    <p>I've got a conditional if statement that should detect if the client has a screen dimension (as opposed to a bot) but always seems to return true:</p> <pre><code>var screenWidth = screen.width, screenHeight = screen.height; // Used elsewhere if (screenWidth &gt;= 1) { // Collate screen size } else { // Do other stuff } </code></pre> <p>As I say, the snippet above <strong>always returns true</strong> and the 'Collate screen size' code is run.</p> <p>I've tried</p> <pre><code>if (screenWidth) { ... if (screenWidth != null) { ... if (screenWidth != '') { ... if (screenWidth === '') { ... if (typeof screen === 'object') { ... if (typeof screenWidth === 'number') { ... </code></pre> <p>All with no success.</p> <p>Yet in my text file (old school I know) I'm getting the following:</p> <pre><code>1385466873 | | x | | ^ </code></pre> <p>Which makes me think the value assigned to the variable is empty!?</p> <p>For reference, I get the following for 'real' browsers:</p> <pre><code>1385465703 | Mac OS X 10.8.4 | 1440 x 900 | undefined | MacIntel ^^^^ </code></pre> <p>See more here: <a href="http://browsertrend.info/client.txt" rel="nofollow">http://browsertrend.info/client.txt</a></p> <hr> <p><strong>More info:</strong></p> <p>Having added the screen.width typeof to the output I now get:</p> <pre><code>1385485905 | Windows 7 | number | 1200 x 1600 | undefined | Win32 ^^^^^^ </code></pre> <p>And nothing, as below:</p> <pre><code>1385485903 | | | x | | ^ </code></pre> <p>So surely testing for:</p> <pre><code>if (typeof screenWidth === 'number') { ... </code></pre> <p>should have worked?</p> <hr> <p>Thanks in advance.</p>

    2. COThat's all done in the first part of the condition (The 'collate screen size' part') - the JS script fires off the data to a PHP script on my server.

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).
