Javascript新手-使用JSFIDLE，缺少分号，但我没有'；我不完全明白在哪里
好的，我正在使用Javascript通过确认函数、提示符和if-else语句创建一个小型业余游戏。 但是，在我的代码中，您可以在这里找到： 第21行和第29行有一个错误，因为缺少分号。我做错了什么？我真的不知道JS的同谋，所以我很迷茫！ 感谢您的帮助Javascript新手-使用JSFIDLE，缺少分号，但我没有'；我不完全明白在哪里,javascript,jsfiddle,Javascript,Jsfiddle,好的，我正在使用Javascript通过确认函数、提示符和if-else语句创建一个小型业余游戏。 但是，在我的代码中，您可以在这里找到： 第21行和第29行有一个错误，因为缺少分号。我做错了什么？我真的不知道JS的同谋，所以我很迷茫！ 感谢您的帮助 更新 根据GitaarLAB的回答，我创建了以下代码： 你怎么看？例如： if (prompt('What are you planning to do? 1.Stay calm and keep everybody in check. or 2
更新
根据GitaarLAB的回答，我创建了以下代码： 你怎么看？例如：
if (prompt('What are you planning to do? 1.Stay calm and keep everybody in check. or 2. Pacnic') === '1.');
if (condition);
if (prompt('What are you planning to do? 1.Stay calm and keep everybody in check. or 2. Pacnic') === '1.');
if (condition);
PS：几行之后你也犯了同样的错误。在你的代码中有很多错误 除了弗朗西斯科·阿丰索在回答中指出的一切之外，我想补充以下几点 最后一行：
window.onload=code地址
在你的小提琴中，你已经选择了“onload”选项（它已经自动包装你的javascript代码）
在else案例中，您有双块{statements here}
您在if
语句中提示了一个问题，然后再次提示相同的问题
现在，如果我清理一些格式和所有错误，并尽可能靠近代码，结果可能如下所示：
function codeAddress(){
var answer;
answer = prompt('Have you played this game?');
if ( answer === 'no'){
confirm('This game is like Zork!');
answer = prompt('Do you need a refresher?')
if (answer === 'yes'){
confirm('All it is, is that you are given a scenario, '
+'in which you are also given actions. '
+'These actions lead you through a certain path '
+'and ending. Pick carefully!');
} else {
confirm('Lets play then!');
}
}
//beginning of game
confirm('Dazed and a little groggy, you realize that you are '
+'trapped on an island after a crash landing. \n'
+'Along with other children, you know it\'d be a best '
+'idea to go and keep everybody calm.');
answer = prompt('What are you planning to do? \n'
+'1. Stay calm and keep everybody in check, or \n'
+'2. Panic.');
if ( answer === '1'){ //stay calm
confirm('That seems like a great idea. \n'
+'You go around the island, doing your best to '
+'convince others to stay calm and keep their composure.');

+'With Piggy on your side as you walk the beach, '
+'you know you had to get an item to get peoples '

+'What would you do? \n'
+'1. Pick up a conch laying on the beach, or \n'
+'2. Take Piggys glasses');
if ( answer === '1') {

工作
其中一个变化是，用户在提示框中键入的字符串存储在变量answer
（该变量的作用域为函数codeAddress
）。
还有一些关于如何使代码更具可读性以及如何在消息/提示框中添加新行的提示
然而，需要注意的最重要的一点是，如果您查看您或我的代码，您可以看到您的故事线的嵌套和缩进将变成一个地狱
因此，你应该开始在故事情节的较小部分分解事情。
此外，您还希望有一个包含所有文本片段的数组，这样您就不需要在逻辑中键入所有文本（稍后可以翻译游戏）
希望这有帮助 您的代码中有很多错误
