Answer 1

function addprotolist() {
  var str = '<label>'+ var_for_text +'</label><input type="hidden" value="'+ var_for_value +'" name="pro_id[]">';
  $('#yourform').append( str );
}

Note

If you want to append multiple input, label etc using loop, don’t call append within loop, it will slow down performance. Make a string like above and call .append() at last out of loop.

For example

var str = '';
function addprotolist(inputObj) {

  // a typical example of inputObj may be
  // inputObj = [ {labelText: 'some 1', value: 'val1' }, {labelText: 'some 2', value: 'val2'} ]

  // loop
  for(var i = 0; i < inputObj.length; i++ ) {
    str += '<label>'+ inputObj[i].labelText +'</label><input type="hidden" value="'+ inputObj[i].value +'" name="pro_id[]">';
  }

  // call append outside of loop
  $('#yourform').append( str );
}

But this way it does not really make sense to use a label. You have to connect it to your input either by wrapping it or by specifying a for attribute pointing to the input’s id:

<!-- Simple label example with for attribute -->  
<input type="radio" name="clickmebutton" id="clickmebutton">
<label for="clickmebutton">Click me</label>  

<!-- or more simply -->  
<label><input type="radio" name="clickmebutton"> Click me</label>
