Question

我是编码的新手，我已经完成了Codecademy的HTML，CSS和Javascript课程，现在我正在制作一个非常简单的游戏。

我正在尝试为我的变量分数添加5，但我不知道怎么做！我可以使用++score添加1，但我不知道如何添加5。

我添加1的简化代码是：

<html>
<head>
<title>Webpage</title>
<script>
var score = 0;
function add1() {
    alert("Adding +1 to your score!");
    ++score;
    alert(score);
    };
</script>
</head>
<body>
<button onclick="add1()";> Add One </button>
</body>
</html>

Answer 1

Javascript中最短/最简单+ 5

 score += 5;

Answer 2

在乐谱中加上+ 5并将其设为分数

 score = score + 5;

Answer 3

function add1() {
    alert("Adding +5 to your score!");
    score = score + 5;
    alert(score);

    };

Answer 4

您可以添加它。如果您禁用警报，则就像Web存储Api。Learn more

var score = 0;
document.getElementById("boy").innerHTML = +score;

function correct() {
alert("And that is correct!")
++score;
document.getElementById("boy").innerHTML = +score;

return true;
}

function wrong() {
alert("And that is wrong!")

return false;
}


var times = 0;
document.getElementById("hey").innerHTML = +score;

function yourname() {
++times;
document.getElementById("hey").innerHTML = +times;

}

<p>
Score:<span id="boy"></span>
</p>

<h2>Is javascript powerful?</h2>

<button onclick='correct()'>Yes</button>
<button onclick='wrong()'>No</button>

<h2>If you went into the w3schools link.This feels familar.</h2>

<p>
You have clicked the button:<span id="hey"></span> times
</p>

<button onclick="yourname()">Click me!!!</button>

您可能看不到代码段。

JavaScript：

 var score = 0;
document.getElementById("boy").innerHTML = +score;

function correct() {
alert("And that is correct!")
++score;
document.getElementById("boy").innerHTML = +score;

return true;
}

function wrong() {
alert("And that is wrong!")

return false;
}


var times = 0;
document.getElementById("hey").innerHTML = +score;

function yourname() {
++times;
document.getElementById("hey").innerHTML = +times;

}

HTML：

<p>
Score:<span id="boy"></span>
</p>

<h2>Is javascript powerful?</h2>

<button onclick='correct()'>Yes</button>
<button onclick='wrong()'>No</button>

<h2>If you went into the w3schools link.This feels familar.</h2>

<p>
You have clicked the button:<span id="hey"></span> times
</p>

<button onclick="yourname()">Click me!!!</button>
