Java Script for first letter caps

Do you want to capitalize the first letter of every word or do you want to convert the words to Title Case where articles and other selected words are not capitalized?

For title case you could use the following document level function:

/*

function titleCaps(title){
var small = "(a|an|and|as|at|but|by|en|for|if|in|of|on|or|the|to|v[.]?|via|vs[.]?)";
var punct = "([!\"#$%&'()*+,./:;<=>?@[\\\\\\]^_`{|}~-]*)";
  var parts = [], split = /[:.;?!] |(?: |^)["Ò]/g, index = 0;
 
  while (true) {
   var m = split.exec(title);

   parts.push( title.substring(index, m ? m.index : title.length)
    .replace(/\b([A-Za-z][a-z.'Õ]*)\b/g, function(all){
     return /[A-Za-z]\.[A-Za-z]/.test(all) ? all : upper(all);
    })
    .replace(RegExp("\\b" + small + "\\b", "ig"), lower)
    .replace(RegExp("^" + punct + small + "\\b", "ig"), function(all, punct, word){
     return punct + upper(word);
    })
    .replace(RegExp("\\b" + small + punct + "$", "ig"), upper));
  
   index = split.lastIndex;
  
   if ( m ) parts.push( m[0] );
   else break;
  }
 
  return parts.join("").replace(/ V(s?)\. /ig, " v$1. ")
   .replace(/(['Õ])S\b/ig, "$1s")
   .replace(/\b(AT&T|Q&A)\b/ig, function(all){
    return all.toUpperCase();
   });
};
   
function lower(word){
  return word.toLowerCase();
}
   
function upper(word){
   return word.substr(0,1).toUpperCase() + word.substr(1);
}

I would then put the following script in the custom format script, validation script, or custom calculation:

event.value = titleCaps(event.value);

Hi,

Please See the Below example for your refernce.

You can make changes accordingly.

   function camelToDash(str) {

      return str.replace(/\W+/g, '-')

                .replace(/([a-z\d])([A-Z])/g, '$1-$2');

   }

   function dashToCamel(str) {

         return str.replace(/\W+(.)/g, function (x, chr) {

                          return chr.toUpperCase();

         })

   }

   var str1 = "devCurry";

   str1 = camelToDash(str1);

   var str2 = "dev-curry";

   str2 = dashToCamel(str2);

   alert(str1 + " " + str2);
