how do I pass count integer into a function?

Question

Here is where I set up my var adultOptions and in this var you will see name="adult'+i+'Name" /> I want that i to be the loop number you see below.

Any ideas?! Thank you

var adultOptions =
'<input type="text"'+
'placeholder="First &amp; Last Name"'+
'required name="adult'+i+'Name"/>'


$('#adults').on('change',function(i){
    numberAppend = $('#adults').val();
    for(i=0; i<numberAppend; i++){
    $(adultOptions).appendTo('#adultOptions');
  }    
});

You are nearly correct with your method. What you are lacking is, maybe the knowledge that a function can be stored in a variable in javascript.

So, now with this knowledge, you can make adultOptions point to a function, like this:

var adultOptions = function(i) {
return '<input type="text"'+
'placeholder="First &amp; Last Name"'+
'required name="adult'+i+'Name"/>';
}

and, then use it like this:

$('#adults').on('change',function(i){
    numberAppend = $('#adults').val();
    for(i=0; i<numberAppend; i++){
    $(adultOptions(i)).appendTo('#adultOptions');
  }    
});

Your string is being defined outside of your for loop (where i is being defined). Put it inside and you should be good.
