Question

所以我跟踪我的问题到函数chargeBmAttk()没有工作，所以我添加了一个警告来创建一个更简单的调试指示;但是，警报不会弹出。函数chargeBmAttk()的语法或HTML代码中的按钮是否有问题？

var playerHp = 45; // Player's health
var enemyHp = 35; // Enemy's health



// Player attack options

function missleAttk()
{ 
var playerDmgs = [5, 10, 15]; // Array of possible damages
var playerRndDmg = playerDmgs[Math.floor(Math.random() * playerDmgs.length]; //          Randomly select integer from array and apply as playerRndDmg
enemyHp = enemyHp - playerRndDmg;
}

function chargeBmAttk()
{
alert("hello world");
//  enemyHp = enemyHp - 5;
}

function waveBmAttk()
{
enemyHp = enemyHp - 7;
}

function iceBmAttk()
{
enemeyHp = enemeyHp - 10;
}


// Enemy attack options


function enemyAttk()
{
var enemyDmgs = [10, 7, 5, 4]; // Array of possible enemy damages
var enemyrRndDmg = enemyDmgs[Math.floor(Math.random() * enemyDmgs.length]; // Randomly select integer from array and apply as enemyRndDmg
playerHp = playerHp - enemeyRndDmg;
}

// Change txt outputs

function changePlayerHp()
{
var oldHp = document.getElementById("disPlayerHp").innerHTML;
var newHp = "Samus" + playerHp + "/ 45";
document.getElementById("disPlayerHp").innerHTML = newHp;

}

function changeEnemyHp()
{
var oldHp = document.getElementById("disEnemyHp").innerHTML;
var newHp = "Metroid" + enemyHp + "/ 35";
document.getElementById("disEnemyHp").innerHTML = newHp;
}


// Game end functions
function win()
{
if (enemyHp <= 0){
alert ("You win!");
}
}

function lose()
{
if (playerHp <= 0){
alert ("You Lose!");
}
}

// Game flow
function flow()
{
changeEnemyHp();
enemyAttk();
changePlayerHp();
win();
lose();
}

Answer 1

this one is correct.you missed two ')' and closing input tag.

<!DOCTYPE html>
<html>
<script>
var playerHp = 45; // Player's health
var enemyHp = 35; // Enemy's health



// Player attack options

function missleAttk()
{ 
var playerDmgs = [5, 10, 15]; // Array of possible damages
var playerRndDmg = playerDmgs[Math.floor(Math.random() * playerDmgs.length)]; //          Randomly select integer from array and apply as playerRndDmg
enemyHp = enemyHp - playerRndDmg;
}

function chargeBmAttk()
{
alert("hello world");
//  enemyHp = enemyHp - 5;
}

function waveBmAttk()
{
enemyHp = enemyHp - 7;
}

function iceBmAttk()
{
enemeyHp = enemeyHp - 10;
}


// Enemy attack options


function enemyAttk()
{
var enemyDmgs = [10, 7, 5, 4]; // Array of possible enemy damages
var enemyrRndDmg = enemyDmgs[Math.floor(Math.random() * enemyDmgs.length)]; // Randomly select integer from array and apply as enemyRndDmg
playerHp = playerHp - enemeyRndDmg;
}

// Change txt outputs

function changePlayerHp()
{
var oldHp = document.getElementById("disPlayerHp").innerHTML;
var newHp = "Samus" + playerHp + "/ 45";
document.getElementById("disPlayerHp").innerHTML = newHp;

}

function changeEnemyHp()
{
var oldHp = document.getElementById("disEnemyHp").innerHTML;
var newHp = "Metroid" + enemyHp + "/ 35";
document.getElementById("disEnemyHp").innerHTML = newHp;
}


// Game end functions
function win()
{
if (enemyHp <= 0){
alert ("You win!");
}
}

function lose()
{
if (playerHp <= 0){

}
}

// Game flow
function flow()
{
changeEnemyHp();
enemyAttk();
changePlayerHp();
win();
lose();
}

Answer 2

var playerRndDmg = playerDmgs[Math.floor(Math.random() * playerDmgs.length)];

var enemyrRndDmg = enemyDmgs[Math.floor(Math.random() * enemyDmgs.length)];

在这2行中缺少大括号)，在纠正你的功能后会调用并提示Hello World

Answer 3

问题在于您的enemyAttk()功能和missleAttk()功能。

function enemyAttk()
{
var enemyDmgs = [10, 7, 5, 4]; // Array of possible enemy damages
var enemyrRndDmg = enemyDmgs[Math.floor(Math.random() * enemyDmgs.length)];//bracket missing here
playerHp = playerHp - enemeyRndDmg;
}

该功能中缺少一个括号。您需要关闭HTML代码中的输入标记。并从代码中删除</button>代码。

功能未运行
