Regex/Javascript to transform Degrees Decimal Minutes to Decimal Degrees

Question

I found a function in the GeoServer source that will allow me to convert Degrees Minutes Seconds to Decimal Degrees in Javascript. But i need to conver Degrees Decim

Answer 1

New function...

dmsToDeg: function(dms) { 
        if (!dms) { 
            return Number.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) { 
            return Number.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; 
    }

I have removed the last part of the regex which captures seconds and fractions of seconds. I have added to the part which captures minutes (?:\.\d+)? This is a non capturing group (?:) - as we don't need it to be captured separate to the integer part of the minutes. It requires a decimal point (\.) and then one or more digits (\d+). The whole group is optional (?) - ie the input can just be integer still.

Edit: Based on your comments I modified it to be a little more white-space-agnostic... It now looks for an integer followed by a space or one of these chars: ".,°d" and that followed by decimal minutes. Solution also posted to your jsfiddle: http://jsfiddle.net/NJDp4/6/
