    <p>The following confuses me greatly. As noted in the comments, the compares seem to work by themselves, but when put together they don't</p> <p>The while should run for all days in the same month, then increment i by one, then start over again. </p> <p>I have laced the whole sequence up with console.log to try to figure it out, but it doesn't make any sense. Everything seems to equal one another, but still fails the "==" test in the while statement. </p> <pre><code> var i=0; var currentdate = 0; var currentmonth = 0; var opensmonth = 0; var opens = [ { "date":"3/30/2006","zip":"30038","latitude":"33.676358","longitude":"-84.15381"}, { "date":"4/31/2006","zip":"30519","latitude":"34.089419","longitude":"-83.94701"} ]; intid = setInterval("stepthrough()", 250); function stepthrough() { //figure out first date. if (currentdate == 0) { // we've not been run before currentdate = opens[0]["date"]; currentmonth = currentdate.split("/", 1); console.log("Current Month: &gt;" + currentmonth +"&lt;"); } console.log("Current month: " + currentmonth + " And opensdate: " + opens[i]["date"].split("/", 1)); // // TWILIGHT ZONE ENTERED. // if (currentmonth == 3 ) { console.log("Current month equals 3."); // PASSES } if (opens[i]["date"].split("/", 1) == 3) { console.log("Opens date equals 3."); // PASSES } // BOTH THE ABOVE TESTS PASS IN CHROME AND SAFARI WHAT THE F*$K JAVASCRIPT while(opens[i]["date"].split("/", 1) == currentmonth) { // WHY DOESNT THIS WORK I HATE COMPUTERS console.log("Trying to add a point one."); addpoint(i); i++; console.log("Trying to add a point."); } //set the date for next iteration currentdate = opens[i]["date"]; currentmonth = currentdate.split("/", 1); console.log ("Current date is now: " + currentdate + " and current month is now: " + currentmonth); jQuery('div#date').text(currentdate); //if (i&gt;=5000) { if (!opens[i]["date"]) { console.log("Clearing interval"); clearInterval(intid); //jQuery('div#date').text("Limited at 5000 records") } } </code></pre>

    2. COWhat happens if you use `===` in the `// WHY DOESNT THIS WORK` line? [This answer](http://stackoverflow.com/questions/359494/javascript-vs-does-it-matter-which-equal-operator-i-use/359509#359509) suggests that `==` is evil and can't be trusted.

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).
