直接上代码
function findMostWord(article) { // 合法性判断 if (!article) return; // 参数处理 article = article.trim().toLowerCase(); let wordList = article.match(/[a-z]+/g), visited = [], maxNum = 0, maxWord = ""; article = " " + wordList.join(" ") + " "; // 遍历判断单词出现次数 wordList.forEach(function(item) { if (visited.indexOf(item) < 0) { // 加入 visited visited.push(item); let word = new RegExp(" " + item + " ", "g"), num = article.match(word).length; if (num > maxNum) { maxNum = num; maxWord = item; } } }); return maxWord + " " + maxNum; }
