我正在尝试使用JavaScript和HTML开发一个21点游戏。
我在REPL上单独使用JavaScript测试了它,它运行得很好,现在我尝试将它移到html页面,以便我最终可以添加一些图形。
然而,当我运行下面的代码时,没有一个玩家的手,房子的手或胜利者出现在屏幕上,但是提示会出现。
有人能看出这有什么问题吗?
function play() {
playersQ = prompt('How many people are playing?');
playershands = [];
i = 0;
count = 0;
var player_cards = 0;
function player() {
var player_cards = Math.floor(Math.random() * 21) + 1;
while (player_cards < 21) {
Hit = prompt('Players cards are ' + player_cards + ' Would you like stick or twist?(S/T)')
if (Hit == 'T') {
player_cards = player_cards + Math.floor(Math.random() * 11) + 1;
} else if (Hit == 'S') {
break;
} else if (player_cards > 21) {
alert('Player is bust');
break;
}
}
return player_cards;
}
function house() {
var house_cards = Math.floor(Math.random() * 21) + 1;
document.getElementById('housecurrenthand').innerHTML = ('House has ' + house_cards);
while (house_cards < 18) {
house_cards = house_cards + Math.floor(Math.random() * 11);
document.getElementById('housecurrenthand').innerHTML = ('House has ' + house_cards);
if (house_cards > 21) {
alert('House is bust')
}
}
return house_cards;
}
while (i < playersQ) {
playershands.push(player());
i = i + 1;
}
var house_hand = house();
while (count < playersQ) {
count2 = count + 1
if (playershands[count] > house_hand && playershands[count] < 22) {
document.getElementById('playershand' + [i]).innerHTML = ('Player ' + count2 + ' has ' + playershands[count]);
document.getElementById('winner').innerHTML = ('Player wins');
count = count + 1;
} else if (house_hand > playershands[count] && house_hand < 22) {
document.getElementById('househand').innerHTML = ('House has' + house_hand);
document.getElementById('winner').innerHTML = ('House wins');
break;
} else if (house_hand == playershands[count]) {
document.getElementById('winner').innerHTML = ('draw');
break;
}
}

您正试图在第66行(function )中使用ID housecurrenthand来达到DOM元素的值,但是在您的html文件中,您已经用ID currenthousehand声明了头(第12行)。
如果你不使用谷歌Chrome,我鼓励你尝试一下。当您按下F12时,会有开发人员工具帮助您找出问题所在。
查看Google Chrome的官方文档,其中有很多关于如何调试web代码的信息。如果您正在使用任何其他浏览器,只需查找文档或教程,如何处理当前的问题。
