Reference A Variable Value With Another Variable

I want to store some number values as variables and then reference them by combining other variables together but I can't insert the values into inner html, only the variable names

Solution 1:

Store codes in object instead of separate variable. Then use bracket notation to construct object key from variables:

var codes = {
  a1: 2.00,
  a2: 4.00,
  a3: 6.00
}

var input1 = $("#one").val(); // gives avar input2 = $("#two").val(); // gives 1, 2 or 3var code = codes[input1 + input2]; // combines input 1 and input 2 to give eg a2document.getElementById("output").innerHTML = code;

Solution 2:

You should use a object to store the values, the you can use Bracket notation to access property from the object obj

var obj = {
  a1: 2.00,
  a2: 4.00,
  a3: 6.00
}

var input1 = 'a';
var input2 = '2';

var code = obj[input1 + input2]; //combines input 1 and input 2 to give eg a2console.log(code);
