如果最后一個單詞是數字并增加數字 - JS，則刪除字符串的最后一個單詞

JavaScript

我有一個字符串，如果最后一個單詞是數字并增加數字，我需要刪除字符串的最后一個單詞。如果最后一個單詞不是數字，我們會一直檢查直到出現相同的單詞，然后將計數與單詞一起拋出。這是Count string occurrence 和 replace with string and count的擴展- JS - 后半部分正在運行。無法使第一個示例正常工作。請指教。例子：Model transfer 2 transfer - Model transfer 3 //預期輸出模型遷移 transfer Transfer - 模型遷移 3 //預期輸出Model transfertransfer Transfer Transfer - Model transfer 4 //預期輸出Model transfer - Model transfer //預期輸出模型 - 模型 //預期輸出var name = "Model Transfer 2 transfer";const name1 = 'Model transfer model transfer';const name2 = 'Model transfer transfer transfer';const name3 = 'Model Transfer transfer Transfer';const name4 = 'Model transfer transfer transfer';const renameNameOccurrence = ( name, occurrenceName) => { var regExp = new RegExp(`(?<=${occurrenceName}\\s)(.+?)(?=\\s+${occurrenceName})`, "ig"); var results = Number(name.match(regExp)[0]); if (typeof results == 'number') { const abc = name.replace(/\w+[.!?]?$/, ''); } const nameSplit = name.split(" "); const occurrenceCount = ( name.match(new RegExp(`${occurrenceName}`, "gi")) || [] ).length; let modifiedName = ""; if (occurrenceCount > 1) { for (let i = 0; i < nameSplit.length - 1; i++) { if (nameSplit[i].toLowerCase() === nameSplit[i + 1].toLowerCase()) { if (occurrenceCount > 1) { modifiedName = name .replace(new RegExp(`\\s*${occurrenceName}\\s*`, "gi"), "") .concat(` ${occurrenceName.toLowerCase()} ${occurrenceCount}`); } else { modifiedName = name; } } else { modifiedName = name; } } } else { modifiedName = name; } return modifiedName;};

該解決方案依賴于按單詞拆分和計算transfer. 它還會檢測最后一個單詞之前是否有整數，如果是，則按以下代碼所述處理這種情況：

var name = "Model Transfer 2 transfer";

const name1 = 'Model transfer model transfer';

const name2 = 'Model transfer transfer transfer';

const name3 = 'Model Transfer transfer Transfer';

const name4 = 'Model transfer transfer transfer';

const renameNameOccurrence = (name, occurrenceName) => {

// split by words as lowercased

let s = name.toLowerCase().split(" ")

// Now count the 'transfer' words

let t = 0;

for (var i = 0; i < s.length; i++) {

if (s[i] == "transfer") {

t++;

}

// Now see if a integer precedes last word

w = s.length - 2; // -2 since length is base 1, and we need word before last

if (w > 1) { // excluding the assumed 1st word Model

if ( parseInt( s[w] ).toString() == s[w]) {

t++; // increment transfer words, since count is consistent

console.log("hello")

}

// Now recompose the string

if (t > 1) {

return name.split(" ")[0] + " Transfer " + t

}

else if (t > 0) {

return name.split(" ")[0] + " Transfer"

}

else {

return name.split(" ")[0]

}

Model transfer 2 transfer - Model transfer 3 //Expected output

Model transfer transfer Transfer - Model transfer 3 //Expected output

Model transfertransfer Transfer Transfer - Model transfer 4 //Expected output

Model transfer - Model transfer //Expected output

Model - Model //Expected output

console.log( renameNameOccurrence( "Model transfer 2 transfer" ))

console.log( renameNameOccurrence( "Model transfer transfer Transfer" ))

console.log( renameNameOccurrence( "Model transfer transfer Transfer Transfer" ))

console.log( renameNameOccurrence( "Model transfer" ))

console.log( renameNameOccurrence( "Model" ))
