If you could use JQuery, you'll simply call .serialize() function on your form object, like follow:

function getQueryString() {
  var str = $( "form" ).serialize();
  console.log(str);
}

$( "#cmdTest" ).on( "click", getQueryString );

  
    opt1
    opt2
  
 
  

  
  

  
  check1
  
  check2
 
  

  
  radio1
  
  radio2

  
Get queryString

Note: It also encode data for use it in url request

I hope it helps you, bye.
