Australian Postcode Place Revisit Tutorial<\/p><\/div>\n

You know how you get to a relatively empty carpark and have more trouble deciding than if it had been chock-a-block? That’s our excuse for all the ways we found for improvement regarding this “where of life” web application, on a revisit to our inhouse Australian Postcode Places web application. Or maybe it was a bad hair day<\/i>, which is a bit implausible!<\/p>\n

The thing is, regarding the recent Australian Postcode Place Initial Bearings Tutorial<\/a>‘s initial bearing<\/i> work, yes, it was calculating bearings, but not between user designated destinations, where it is of more practical use. It was calculating bearings to and from that initial place, and except for dreaming of places way away<\/i> purposes, out the window … like … why aren’t you working!<\/sup>?<\/sub> … or maybe orienteering … it is not so useful. In any case, we hate to lose “backward compatibility”, so hived off these previous calculations to the title of some of the middle cells, and added new “between postcode place” bearing calculation places where it is more apt, and immediately visible.<\/p>\n

And then on the other “outward facing” yellow cells we added onclick<\/i> and\/or ondblclick<\/i> event logic to show Google Map<\/a> and Wikipedia<\/a> webpages, thanks, associated with those postcode places, as additional functionality …<\/p>\n

<?php echo ”
\n
\n function rhclick(dthis) {
\n var onebefore=null, lastoned=null;
\n if (('' + dthis.title).indexOf(',') == -1 && ('' + dthis.id).indexOf('setofthree_') == 0) {
\n var divsare=document.getElementsByTagName('div');
\n for (var ikj=0; ikj<divsare.length; ikj++) {
\n if (!onebefore) {
\n if (('' + divsare[ikj].id).indexOf('setofthree_') == 0) {
\n if (('' + dthis.id) == ('' + divsare[ikj].id)) {
\n if (lastoned) {
\n dthis=lastoned;
\n onebefore=lastoned;
\n }
\n } else {
\n lastoned=divsare[ikj];
\n }
\n }
\n }
\n }
\n }
\n if (('' + dthis.title).indexOf(',') != -1 && ('' + dthis.innerHTML).trim() != '') {
\n \/\/ https:\/\/www.google.com\/maps?z=9&t=m&q=loc:-37.763584+144.942222
\n if (lastwois.trim() == '\/\/www.google.com\/maps?z=9&t=m&q=loc:' + ('+' + dthis.title).replace(\/^\\+\\-\/g,'-').replace(',','+').replace('+-','-')) {
\n if (lastwois == lastwois.trim()) {
\n lastwois+=' ';
\n window.open('\/\/\/\/wikipedia.org\/wiki\/' + encodeURIComponent(dthis.innerHTML.replace(\/\\ \/g,'_')), '_blank', 'top=110,left=110,height=600,width=800');
\n }
\n } else {
\n lastwois='\/\/www.google.com\/maps?z=9&t=m&q=loc:' + ('+' + dthis.title).replace(\/^\\+\\-\/g,'-').replace(',','+').replace('+-','-');
\n window.open('\/\/www.google.com\/maps?z=9&t=m&q=loc:' + ('+' + dthis.title).replace(\/^\\+\\-\/g,'-').replace(',','+').replace('+-','-'), '_blank', 'top=100,left=100,height=600,width=800');
\n }
\n }
\n }
\n<\/code>
\n“; ?><\/p>\n

And then there were those “nearby place calculation” improvements. And then there was what to do with a postcode entry that doesn’t exist<\/i>. And then, in the great Australian Postcodes database<\/a>, thanks, some postcodes do not have associated latitude and longitude defined, and we decided to use the nearest defined set that appears before any ones that are undefined, here, as our solution to this issue.<\/p>\n

All in all, we think, it’s a better<\/a> australia_place_crowfly_distances.php<\/a>‘s live run<\/a> link you should feel free to (re-)try.<\/p>\n
