javascript - 通过自定义字母表javascript对字符串函数进行排序

Question

尝试根据自定义字母表对字符串数组进行排序。可能其中有一些不必要的代码，但那是几个不同的迭代混合在一起的结果。

我正在对第一个字母进行基本排序，如果这不起作用，我将调用深度排序函数并开始对字母进行排序。但是结果只是按首字母排序，后面的排序就显得随意了。

有什么帮助吗？

var wordArray = ['apple', 'abbot', 'aatrophy', 'banana', 'berry', 'cherrypie', 'cherry', 'candy', 'grapefruit', 'pear', 'pizza', 'zebra', 'cigarette', 'guitar'];
var wordToLetterArray = [];
// var sortingString = "kwfhjrsbdtqmxaopzvieulgcny";
var sortingString = "abcdefghijklmnopqrstuvwxyz";

var deepSort = function(wordArray1, wordArray2) {
var forLoopIterations = 0;
if (wordArray1 && wordArray2) {
    if (wordArray1.length > wordArray2.length) {
        forLoopIterations = wordArray2.length;
    } else {
        forLoopIterations = wordArray1.length;
    }

    for (var i = 0; i <= forLoopIterations; i++) {
        if (sortingString.indexOf(wordArray1[i]) > sortingString.indexOf(wordArray2[i])) {
            return -1;
        } else if (sortingString.indexOf(wordArray1[i]) < sortingString.indexOf(wordArray2[i])) {
            return 1
        } else {
            if (i >= forLoopIterations) {
                if (wordArray1.length > wordArray2.length) {
                    return 1;
                } else if (wordArray1.length < wordArray2.length) {
                    return -1
                } else {
                    return 0
                }
            } else {

            }

        }
    };
} else {
    return 0;
}

}

var populateWordToLetterArray = function() {
for (var i = 0; i <= wordArray.length - 1; i++) {
    wordToLetterArray.push([]);
    for (var x = 0; x <= wordArray[i].length - 1; x++) {

        wordToLetterArray[i].push(wordArray[i][x]);
    };
};
sortWordArraybyFirstLetter();
}



var sortWordArraybyFirstLetter = function sortWordArraybyFirstLetter() {
wordArray.sort(function(a, b) {
    var aIndex = sortingString.indexOf(a[0]);
    var bIndex = sortingString.indexOf(b[0]);
    if (aIndex > bIndex) {
        return 1;
    } else if (aIndex < bIndex) {
        return -1;
    } else {

        return deepSort(wordToLetterArray[wordArray.indexOf(a)], wordToLetterArray[wordArray.indexOf(b)]);


    }
})

}




populateWordToLetterArray();
console.log(wordArray);
console.log(wordToLetterArray);

创建一个将单词“翻译”成自定义字母表的函数，然后通过比较它们的“翻译”对单词进行排序:

function translate(str, alphabet) {
    var abc = "abcdefghijklmnopqrstuvwxyz";
    return [].map.call(str, function(c) {
        return alphabet[abc.indexOf(c)] || c;
    }).join("");
}

var wordArray = ['apple', 'abbot', 'aatrophy', 'banana', 'berry', 'cherrypie', 'cherry', 'candy', 'grapefruit', 'pear', 'pizza', 'zebra', 'cigarette', 'guitar'];
var sortingString = "kwfhjrsbdtqmxaozpvieulgcny";

wordArray.sort(function(a, b) {
    return translate(a, sortingString).localeCompare(translate(b, sortingString));
});

document.write(wordArray)

这不是特别有效，但仍有优化空间。
