JavaScript 中的字谜查找器

我应该用 JavaScript 编写一个程序来查找所提供的一系列单词中的所有字谜。例如。：

monk, konm, nkom, bbc, cbb, dell, ledl, llde

输出应分为几行：

1. monk konm, nkom;
2. bbc cbb;
3. dell ledl, llde;

我已经将它们按字母顺序排序并将它们放入一个数组中。 IE。：

kmno kmno bbc bbc dell dell

然而，我一直在比较和寻找数组中匹配的字谜。

任何帮助将不胜感激。

Javascript 对象非常适合此目的，因为它们本质上是键/值存储：

// Words to match
var words = ["dell", "ledl", "abc", "cba"];

// The output object
var anagrams = {};

for (var i in words) {
    var word = words[i];

    // sort the word like you've already described
    var sorted = sortWord(word);

    // If the key already exists, we just push
    // the new word on the the array
    if (anagrams[sorted] != null) {
        anagrams[sorted].push(word);
    } 
    // Otherwise we create an array with the word
    // and insert it into the object
    else {
        anagrams[sorted] = [ word ];
    }
}

// Output result
for (var sorted in anagrams) {
    var words = anagrams[sorted];
    var sep = ",";
    var out = "";
    for (var n in words) {
        out += sep + words[n];
        sep = "";
    }
    document.writeln(sorted + ": " + out + "<br />");
}
