Javascript camel case split for json result

In javascript json column names, I want to Split camel case string for example CustomerID => Customer ID

Below code working but splitting as Customer I D

 var title = field.replace(/([a-zA-Z][a-z]*)/g, " $1");

I don't want to split abbreviated words or consecutive Caps, how can I achieve this.

Also I want to make first letter uppercase if it is a small letter.

You can pass a function into the replace() and call toUpperCase

"custID".replace(/([a-z])([A-Z])/g,"$1 $2").replace(/^([a-z])/, function(a){ return a.toUpperCase();});

You can use:

var title = field
              .replace(/([a-z]+)([A-Z]+)/g, "$1 $2")  // "aaAA" => "aa AA"
              .replace(/([A-Z]+)([a-z]+)/g, "$1 $2") // "AAaa" => "AA aa"
              .replace(/^([a-z])/g, function(x, y) { return y.toUpperCase(); }); // caps first char

If field is "aaaAAAbbDDD", the above will return "Aaa AAA bb DDD"

= field.charAt(0).toUpperCase() + field.replace(/([a-z])(?=[A-Z])/g, "$1 ").slice(1);
