我已经在互联网上寻找解决方案，但我不确定为什么这不会出现在浏览器中。它可以在javascript的repl中工作，但由于某种原因，它不会在我的谷歌浏览器中打开。
<script>function numbergame() {
colors = ["Red", "Green", "Blue", "Orange", "Yellow", "Indigo", "Violet", "Gray", "Black", "White"]
var random_color = colors[Math.round(Math.random()*colors.length)]
var guesses = 0;
var thecolor = false;
var playerguess;
while (!thenumber) {
playerguess = prompt("I am thinking of a number color from this list:n" +color +"nCan you guess which one it is?");
guesses+=1;
thenumber = checkguess()
};
function checkguess() {
if (!colors.include(playerguess)) {alert("Please enter a valid color"); return false}
if (playerguess<random_color) {alert("Hint: the answer is lower alphabetically.");return false}
if (playerguess>random_color) {alert("Hint: the answer is higher alphabetically.");return false}
else {alert("You've guessed the color! It was " + random_number+" and it took you " + guesses+ " tries.");
myBody=document.getElementsByTagName("body")[0];
myBody.style.background=thecolor;
return true;}
}</script>
<!doctype html>
<html>
<head>
Color Game.
</head>
<body onload= "numbergame()"></body>
</html>没有右大括号来匹配行上的大括号：
while (!thenumber) {
使用正确的缩进和格式将使此类错误更容易找到。
你写的不是有效的 HTML。
您的<script>标签必须放置在 HTML 文档的<body>或<head>中，而不是放在文档类型之前的开头。
这个HTML文件有很多问题。我已经纠正了这些问题，但即使修复了，它的编码仍然很糟糕。但是，这里是...
<!DOCTYPE html>
<html>
<head>
<script>
'use strict';
function numbergame() {
var colors = ["Red", "Green", "Blue", "Orange", "Yellow", "Indigo", "Violet", "Gray", "Black", "White"];
var random_color = colors[Math.round(Math.random()*colors.length)];
var guesses = 0;
var thecolor = false;
var playerguess;
var thenumber = false;
while (!thenumber) {
playerguess = prompt("I am thinking of a number color from this list:n" + colors + "nCan you guess which one it is?");
guesses += 1;
thenumber = checkguess(colors, playerguess, random_color, guesses);
}
};
function checkguess(colors, playerguess, random_color, guesses) {
if (!colors.includes(playerguess)) {
alert("Please enter a valid color"); return false
}
if (playerguess < random_color) {
alert("Hint: the answer is lower alphabetically.");
return false;
}
if (playerguess > random_color) {
alert("Hint: the answer is higher alphabetically.");
return false;
} else {
alert("You've guessed the color! It was " + random_color + " and it took you " + guesses + " tries.");
var myBody = document.getElementsByTagName("body")[0];
myBody.style.background = random_color;
return true;
}
}
</script>
</head>
<body onload="numbergame()">
<h1>Color Game</h1>
</body>
</html>
这些问题是未声明的变量、缺少大括号、范围问题、错误位置的<script>标签等。老实说，你最好自己从头开始编码。
我在火狐 47.0.1 上对此进行了测试。您可能会遇到其他浏览器兼容性问题，但我相信您可以从这里自己解决这些问题:)
数字游戏函数中的while循环应如下所示：
while (!thenumber) {
playerguess = prompt("I am thinking of a number color from this list:n" +color +"nCan you guess which one it is?");
guesses+=1;
thenumber = checkguess();
} // <-- this curly brace was missing
