combining switch loops to concatenate the result - arrays

Question

Please forgive my noob-ness.
So, i figured out how to create two separate switch loops, in order to access two separate values. My trouble now, is that I don't know how to write a function that would allow me to concatenate the results of the two switch values.
var select = document.getElementById('weather');
var para = document.getElementById('alf');
var door = document.getElementById('dance');
var mort = document.getElementById('tim');
document.getElementById('weather').addEventListener('change',
setWeather);
document.getElementById('dance').addEventListener('change',
setDance);
function setWeather() {
var choice = this.value;
switch(choice) {
case 'sunny':
para.textContent = "fly me to the Moon";
break;
case 'rainy':
para.textContent = "let me sail amongst the stars";
break;
case 'snowy':
para.textContent = "life on Jupiter and Mars";
break;
default:
para.textContent = "";
}
}
function setDance() {
var art = this.value;
switch(art) {
case 'hail':
mort.textContent = "in other words";
break;
case 'rail':
mort.textContent = "darling kiss me";
break;
case 'cat':
mort.textContent = "please be true";
break;
default:
mort.textContent = "";
}
}
function result() {
weatherVal = weather.value;
danceVal = dance.value;
para.textContent = weatherVal + danceVal;
}
I tried to use the above code "function result()" to write the function to create the concatenation, but no success. I feel like the answer is right in front of me, but I'm just not quite sure what's going on.

Answer 1

You could make choice and art global variables and then use them in result like this:
var select = document.getElementById('weather');
var para = document.getElementById('alf');
var door = document.getElementById('dance');
var mort = document.getElementById('tim');
document.getElementById('weather').addEventListener('change', setWeather);
document.getElementById('dance').addEventListener('change', setDance);
var choice;
var art;
function setWeather() {
choice = this.value;
switch(choice) {
case 'sunny':
para.textContent = "fly me to the Moon";
break;
case 'rainy':
para.textContent = "let me sail amongst the stars";
break;
case 'snowy':
para.textContent = "life on Jupiter and Mars";
break;
default:
para.textContent = "";
break;
}
}
function setDance() {
art = this.value;
switch(art) {
case 'hail':
mort.textContent = "in other words";
break;
case 'rail':
mort.textContent = "darling kiss me";
break;
case 'cat':
mort.textContent = "please be true";
break;
default:
mort.textContent = "";
break;
}
}
function result() {
para.textContent = choice + art;
}
