How can this be sorted correctly?

var coords = [1,'3',7,8,'9',11,'12',15,17,'19',25,'27','44','49',111,'112',188,'199'];
alert( 'Unsorted: '+coords.join(' | ') +'\nSorted: '+ coords.sort().join(' | ') )

What do you mean by 'sorted correctly'?  When you mix number and text formats like that, you will probably have to do something to put them all in the same format.  If you make them all numbers, you can sort in numerical order where 44 would come before 111.  If you make them all text, then '111' would come before '44'.

alert( 'Unsorted: '+coords.join(' | ') +'\nSorted: '+ coords.sort(function(a,b){return a-b}).join(' | ') )
