Submitig form with jquery

Submitig form with jquery

    I have simple code here, on click on submit am preventing default , and validating some data with ajax etc . 
    After i done validation i just want to continue form submitting .
    I have tried with ('form').submit() but it is not working !? ( I have only one form on page and am selecting it )
    1. $(document).ready(function(){
    2. $('input[name=submit]').on('click',function(event){
    3. event.preventDefault();
    4. ....
    5.                if (something){
    6.                //   submit my form
    7.                   }
    8. })
    9. })
    10. })
    Plz help , thx
