JavaScript How to create an empty JQuery element and populate it? create empty jquery object,create empty jquery array,create empty

If all you are trying to do is create the inputs and append them to the form, you can use a simple array, or map the elements. $.map can be used to loop over an array, create new elements, and return them as a list at the end. Using this we can create the array, and then append them all at once to the form.

const forms_data = ['Name', 'Email'];

$('form').append($.map(forms_data, function(element){
  return `<input placeholder="${element}" / >`;
}));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form></form>
Answer:1

You're right to use $(), but those APIs won't work. Instead use .add():

form = form.add($(`<input placeholder="${input_name}" / >`));

As the other answer notes, if you initialize the element to a <form> element then you can use the other APIs, but if you've already got a <form> on the page then that will be problematic. You could in that case initialize the container to something harmless like a <div> or a <span>.
