4 years ago Great, thanks for the offer. I’ve thought about this a bit and there was something in the way it’s now implemented that gave me pause, but now I forgot what that was. Also be aware that this was literally my first multi page piece of JS code and it's probably very “nooby”, so eyeroll/facepalm warning :). It probably reads more like C than actual JS … I still want to keep is as pure JS as possible but I’m aware that many things could be improved anyway.
Looking at the code now (after 3 years), I think the 4 text boxes trlat2, etc. would need to be set to not readonly and have a callback when enter was pressed, either 4 separate callbacks or one that’s fired if one or more of the 4 have been changed. Or, instead of enter callbacks something like a loose focus callback?
<!-- Put the box corner coords here so they get transmitted with get -->
<input type="text" id="trlat2" name="trlat" maxlength="7" size="7" value="NULL" title="(trlat)" readonly> N
<input type="text" id="trlon2" name="trlon" maxlength="8" size="8" value="NULL" title="(trlon)" readonly> E (Top right corner)<br>
<input type="text" id="bllat2" name="bllat" maxlength="7" size="7" value="NULL" title="(bllat)" readonly> N
<input type="text" id="bllon2" name="bllon" maxlength="8" size="8" value="NULL" title="(bllon)" readonly> E (Lower left corner) <br>
<br>In each of those callbacks, the appropriate side of the bounds of the global rectangle has to be changed, similar to this but with set instead of get:
let b = rectangle.getBounds();
let trlat = b.getNorthEast().lat();
let trlon = b.getNorthEast().lng();
let bllat = b.getSouthWest().lat();
let bllon = b.getSouthWest().lng();If you ever get started on this and need help, please ping me!
Cheers
