    <p>I really need help calculating the difference between two dates and it has to be the number of days in a whole number. Here is my HTML and jQuery..</p> <p>This is not working at all... The site should say the date today. Then the user would picka date and click the button "Check our safety record" and at the bottom of the page it says how many days it has been. The jQuery:</p> <pre><code>$(document).ready(function() { $('#safetyRecord').hide(); var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; var dayNames= ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"] var newDate = new Date(); newDate.setDate(newDate.getDate()); $('#today').html(dayNames[newDate.getDay()] + "," +' ' + monthNames[newDate.getMonth()] + ' ' + newDate.getDate() + ","+ ' ' + newDate.getFullYear()); /* $(':button').click(function(){ var start = $('#dateOfLastAccident').val(); var end = $('#today'); var startDate = new Date(start); var endDate = new Date(end); var diff = endDate - StartDate; var numDays = Math.floor( diff / 1000 /60 /60 /24 ); $('#daysSinceLastAccident'+ numDays)(); */ }); </code></pre> <p>The HTML:</p> <pre><code>&lt;!doctype html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;meta charset="utf-8"&gt; &lt;title&gt;generic safety&lt;/title&gt; &lt;link rel="stylesheet" href="L3hw.css"&gt; &lt;!-- jQuery library hosted by Google Content Distribution Network --&gt; &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"&gt;&lt;/script&gt; &lt;script src="L3hw.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;header&gt; &lt;img src="images/genericBanner.png" alt="Generic, Inc."&gt; &lt;p&gt; The New Ventures Mission is to scout profitable growth opportunities in relationships, both internally and externally, in emerging, mission-inclusive markets, and explore new paradigms and then filter and communicate and evangelize the findings. &lt;/p&gt; &lt;/header&gt; &lt;section id="main"&gt; &lt;h1&gt;Safety at generic company&lt;/h1&gt; &lt;h2&gt;Today is &lt;span id="today"&gt;TBD&lt;/span&gt;.&lt;br&gt; Our last lost-work accident was on &lt;input type="date" id="dateOfLastAccident"&gt; &lt;button type="button" id="checkRecord"&gt;Check our safety record&lt;/button&gt; &lt;/h2&gt; &lt;h2 id="safetyRecord"&gt; It has been &lt;span id="daysSinceLastAccident"&gt;TBD&lt;/span&gt; days since our last lost-work accident. &lt;/h2&gt; &lt;/section&gt; &lt;!-- end main --&gt; &lt;footer&gt; &lt;p id="message"&gt; &lt;!-- (an appropriate safety message will appear here) --&gt; &lt;/p&gt; &lt;p&gt;&lt;img src="images/genericBullet.png" alt="*"&gt; Generic Company - we do stuff&lt;/p&gt; &lt;/footer&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

Querying!

 
Guidance
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).
