I answered this on the original question: Regex/Javascript to transform Degrees Decimal Minutes to Decimal Degrees
Solution posted to your fiddle: http://jsfiddle.net/NJDp4/6/
dmsToDeg: function(dms) {
if (!dms) {
returnNumber.NaN;
}
var neg= dms.match(/(^\s?-)|(\s?[SW]\s?$)/)!=null? -1.0 : 1.0;
dms= dms.replace(/(^\s?-)|(\s?[NSEW]\s?)$/,'');
var parts=dms.match(/(\d{1,3})[.,°d ]?\s*(\d{0,2}(?:\.\d+)?)[']?/);
if (parts==null) {
returnNumber.NaN;
}
// parts: // 0 : degree // 1 : degree // 2 : minutes var d= (parts[1]? parts[1] : '0.0')*1.0;
var m= (parts[2]? parts[2] : '0.0')*1.0;
var dec= (d + (m/60.0))*neg;
return dec;
}
The reason this was working for "-113 40.54687527" but not for "77 50.51086497" is that the code was ripping out spaces and the sign (leaving "11340.54687527" and "7750.51086497") and then grabbing the first 3 digits to use as degrees (so "113" and "775"). I've modified this so that it no longer strips out spaces before grabbing the two numbers.
