If you are accessing a numeric value, to keep leading zeros use the 'valueAsString' property if you want to drop the leading zeros, use 'toString()' method to the value. Numbers are not stored as character strings and unless you force them to a type of string value there string character length is zero.

Also if you convert to the the string values for numeric fields you can use the 'sbstr()' or 'substring()' JavaScript methods.

Some code you can try in the JavaScript console or in a button action:
console.show();var sNumber = '01234567890.987654321';console.println('String number: ' + sNumber)console.println('typeof: ' + typeof sNumber)console.println('length: ' + sNumber.length)var fNumber = Number(sNumber);console.println('floating point number: ' +fNumber)console.println('typeof: ' + typeof fNumber)console.println('length: ' + fNumber.length)var sFNumber = sNumber.toString();console.println('floating point number to string: ' +sFNumber)console.println('typeof: ' + typeof sFNumber)console.println('length: ' + sFNumber.length)console.println('substr')console.println('String nubmer: ' + sNumber.substr(0,3) );try {console.println('Floating point nubmer: ' + fNumber.substr(0,3) );} catch(e) {console.println(e.toString() );}console.println('substring");console.println('String nubmer: ' + sNumber.substring(0,3) );try {console.println('Floating point nubmer: ' + fNumber.substring(0,3) );} catch(e) {console.println(e.toString() );}
