Javascript刽子手游戏问题

标签： javascript arrays

我一直在使用HTML模板和javascript为一个类的项目开发一个刽子手游戏。

我目前遇到了一些问题。 1.我正在使用一个阵列来调用图片进行错误的猜测，以便在绞架中添加部件。当发生4次错误猜测时，只显示图片＃4。 2.我也有一个问题，那就是只有某些单词才能确定按钮决定实际工作和字母＆＃34; o＆＃34;从来没有工作

非常感谢任何帮助。

3 个答案:

答案 0 :(得分：2)

您的图片无法正常工作，因为您将数组用作字符串。

document.getElementById("images").src =image+".gif";

应该是

document.getElementById("images").src ="image"+NumberOfChances+".gif";

否则，你正在做的是获取所有图像的html并将其设置为图像的src属性。

<img src="<img src="image0.jpg" align ="left" width="415" height="496">, <img src="image1.jpg" align ="left" width="415" height="496">, <img src="image2.jpg" align ="left" width="415" height="496">..." id="images"> This isn't what you want!

而且，我认为你已经把你的jpgs和gif混淆了。检查文件扩展名。

另外，你有50个单词，你没有在这里展示吗？你的数组包含13，但后来你写了

theWord = words[Math.floor(Math.random()*51)];

这似乎表明你有一个不到51或50个单词。

在你的信函中，我认为你并没有完全理解for循环的概念。你似乎在想的是每次调用函数时都会发生一次新的迭代，但事实并非如此。相反，每次使用您猜到的一个字母调用函数时，for循环都会遍历整个单词。因此，除非单词中的每一个字母都是o，否则如果你猜出字母o，你将为单词中的每个o得到一个点，并且每个字符都不会得到-1，这不是＆＃39; 39; t你想要什么。抛弃for循环，每次运行函数时都使用i ++。

答案 1 :(得分：0)

function swap(image)
{
        document.getElementById("images").src =image+".gif";

}

尝试将gif更改为jpg

答案 2 :(得分：0)

if (!correctGuess)
{
    NumberOfChances++;
    swap(image[NumberOfChances]);
