Javascript replace string by another String

Question

I have following string in javascript.

var str = 'P24 + P33'; //p24 is just exp. it will be any number i.e. P98

I Want to replace this string into following string using jquery replace.

var str = "$('#p24').val() + $('#p33').val()";

Your intent is not clear at all. What is the output you're trying to achieve? What do the `P24` and `P33` variables contain? — Rory McCrossan, Oct 14 '16 at 10:29

var str = 'P24 + P33'; //p24 is just exp. it will be any number i.e. P98
var str_array = str.split(" + ");
console.log("Original string: "+str);
for(var i = 0; i < str_array.length; i++){
  str_array[i] = $("#"+str_array[i]).html();
}
var replaced_string = str_array.join(" + ");
console.log("Replaced string: "+replaced_string);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="P24">this is P24</div>
<div id="P33">this is P33</div>
