Jquery - validation - Rules

I use JQ - validation plugin to validate my form. But i dont know what kind of validation rules in jquery! Could you suggest me a page where i can read about rules?

I have two field, NAME and AGE, and i want it to validate for REQUIRED, MAXLENGTH, NUMBER /CHAR, MIN, MAX

 rules: {
    new_name: {
    required: true,
    maxlength: 30,
    **number: false  //?? I dont want to allowd numbers, only alphabetic chars.**

 },
 new_age: {
    required: true,
    maxlength: 3,
    **chars: false  //?? I dont want to allowd numbers, only alphabetic chars.**
    **min: 1 // 1 is the lowest number what they allowed**
     **max: 30 // 120 is the highest number what they allowed**
 },

Is it possible, without write an own rule?

Thank you.
