Variable variables in JavaScript within a loop

var x = 1;
var ctr = 5;
while (x<=ctr)
var ss_+x = $('input[name=IDMenu_'+x+']').val();
x++;



As you can see above I have a loop that will iterate through input fields with the name IDMenu_1 through to IDMenu_5. I attempted to make the variable names themselves variable by using the syntax var ss_+x; however this is incorrect and does not work.

IDMenu_1

IDMenu_5

var ss_+x

If I were to not use a loop, this is what I would be doing:

var ss_1 = $('input[name=IDMenu_1]').val();
var ss_2 = $('input[name=IDMenu_2]').val();
var ss_3 = $('input[name=IDMenu_3]').val();
var ss_4 = $('input[name=IDMenu_4]').val();
var ss_5 = $('input[name=IDMenu_5]').val();


Is it possible to accomplish this within a loop?

var ss_+x

var ss = ;

ss.push($('input....val());

You're trying to create variables with dynamic names so you could use window[variable_name].

window[variable_name]

NOTE: IMO you could use an array of values instead in this case.

var x = 1;
var ctr = 5;

while (x <= ctr)
window["ss_" + x] = $('input[name=IDMenu_' + x + ']').val();
x++;


console.log(ss_1, ss_2, ss_3, ss_4, ss_5);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<input name="IDMenu_1" value="10">
<input name="IDMenu_2" value="20">
<input name="IDMenu_3" value="30">
<input name="IDMenu_4" value="40">
<input name="IDMenu_5" value="50">

ss

var ss = ; while(...) ss[x] = ...;

ss.1, ss.2, ...

It'd be better to make the var an array, then push the items to it.

var x = 1;
var ctr = 5;
var ss = ;
while (x<=ctr)
ss.push($('input[name=IDMenu_'+x+']').val());
x++;



You'll then have the values in

console.log(ss[0]);
console.log(ss[1]);
// ...
