JavaScript updating a global variable
I am not the most proficient in Javascript at this time and I am trying to learn in half. Anyway ... how can I update the balance variable more efficiently?
I currently believe I am doing it wrong. Also my button doesn't work on click event.
Anything that would be a huge help! Thank.
// Set global variables
var name;
var balance;
var weed;
// Ask the user his name for his character
name = window.prompt("What is your name?", "Cap'n Grow");
var finalName = document.getElementById('name');
finalName.textContent = name;
// Set the balance to default
balance = 100;
var FinalBalance = document.getElementById('balance');
FinalBalance.textContent = balance;
// Set the balance of weed to default
weed = 10;
var FinalWeed = document.getElementById('gear');
FinalWeed.textContent = weed;
// Sell function
function sellGear() {
var check = window.prompt("Are you sure you want to sell 5 bags?", "Yes");
if (check === 'Yes' && weed >= 5) {
console.log("Transaction was successful!");
// Update the balance
var updBalance = document.getElementById('balance');
updBalance.textContent = balance + 150;
} else {
console.log("Failed!")
}
}

Here is the solution and suggestion: Try using the java script code at the end of your HTML.
<html lang="en">
<head>
<title></title>
<link rel="stylesheet" href="css/normalize.css">
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<div id="container">
<header>
<div class="dashboard">
<div id="name"></div>
<div id="balance"></div>
<div id="gear"></div>
<div id="sell">
<button id="sellButton" onclick="return sellGear();">Sell?</button>
</div>
</div>
</header>
</div>
</body>
<script src="js/global.js"></script>
</html>
<SCRIPT>
// Set global variables
var name;
var balance;
var weed;
// Ask the user his name for his character
var name = window.prompt("What is your name?", "Cap'n Grow");
var finalName = document.getElementById('name');
finalName.textContent = name;
// Set the balance to default
var balance = 100;
var FinalBalance = document.getElementById('balance');
FinalBalance.textContent = balance;
var weed = 10;
var FinalWeed = document.getElementById('gear');
FinalWeed.textContent = weed;
// Sell function
function sellGear() {
var check = window.prompt("Are you sure you want to sell 5 bags?", "Yes");
if (check === 'Yes' && weed >= 5) {
console.log("Transaction was successful!");
// Update the balance
var updBalance = document.getElementById('balance');
updBalance.textContent = balance + 150;
} else {
console.log("Failed!")
}
}
</SCRIPT>
