研究了前輩的作業才發向若要讓input的值可以被檢查就不能限定number，要不然輸入非number會直接show出來，卡這個很久... 因為想學quasar的樣式(range條的顏色變化等)做了些研究，後來嘗試把所有想法塞進去，結果做出來是蠻炫的但不是很好看... 心得：覺得老師的出題方向就是幫助學生從業界的需求去學習，然後一點一點從小地方開始做，並且能夠自行研究，而且不強調怎麼寫，而是確實做出來，很務實的取向，覺得獲益良多，上完9堂課默默繳了不貴的學費，有新的課堂會再回來做。目前正嘗試自行開發一個網頁應用，寫cdoe真的要很有耐心，其實想想現在有很多輔助/查詢工具真的很方便，越寫越佩服那些做框架的人...

在 JavaScript 中使用 Regex 正規表示式：懶人 Cheat Sheet 備忘單

需要字串比對、搜尋等等功能時，regex 正規表示式非常好用。以下是一份 regex 的備忘單，方便需要時可以翻閱。 - 原文出處：https://dev.to/emmabostian/regex-cheat-sheet-2j2a --- **測試正規表示式** - 使用 `.test()` 方法 ``` let testString = "My test string"; let testRegex = /string/; testRegex.test(testString); ``` **測試多種模式** - 使用 OR 運算子 (|) ``` const regex = /yes|no|maybe/; ``` **忽略大小寫** - 使用 `i` 標誌不區分大小寫 ``` const caseInsensitiveRegex = /ignore case/i; const testString = 'We use the i flag to iGnOrE CasE'; caseInsensitiveRegex.test(testString); // true ``` **將第一個符合項提取到變數** - 使用 `.match()` 函數 ``` const match = "Hello World!".match(/hello/i); // "Hello" ``` **提取所有符合項到陣列中** - 使用`g`標誌 ``` const testString = "Repeat repeat rePeAT"; const regexWithAllMatches = /Repeat/gi; testString.match(regexWithAllMatches); // ["Repeat", "repeat", "rePeAT"] ``` **匹配任意字元** - 使用通配字元`.`作為任何字元的佔位符 ``` // To match "cat", "BAT", "fAT", "mat" const regexWithWildcard = /.at/gi; const testString = "cat BAT cupcake fAT mat dog"; const allMatchingWords = testString.match(regexWithWildcard); // ["cat", "BAT", "fAT", "mat"] ``` **用多種可能性匹配單個字元** - 定義一組您希望匹配的字元 - 放在中括號內即可`[]` ``` // Match "cat" "fat" and "mat" but not "bat" const regexWithCharClass = /[cfm]at/g; const testString = "cat fat bat mat"; const allMatchingWords = testString.match(regexWithCharClass); // ["cat", "fat", "mat"] ``` **匹配字母表中的字母** - 使用字元集合 `[a-z]` ``` const regexWithCharRange = /[a-e]at/; const catString = "cat"; const batString = "bat"; const fatString = "fat"; regexWithCharRange.test(catString); // true regexWithCharRange.test(batString); // true regexWithCharRange.test(fatString); // false ``` **匹配特定的數字和字母** - 還可以使用連字符來匹配數字 ``` const regexWithLetterAndNumberRange = /[a-z0-9]/ig; const testString = "Emma19382"; testString.match(regexWithLetterAndNumberRange) // true ``` **匹配一個未知字元** - 要匹配您*不*想要的一組字元，請使用否定字元集 - 使用插入符號 `^` 即可 ``` const allCharsNotVowels = /[^aeiou]/gi; const allCharsNotVowelsOrNumbers = /[^aeiou0-9]/gi; ``` **匹配連續出現一次或多次的字元** - 使用`+`符號 ``` const oneOrMoreAsRegex = /a+/gi; const oneOrMoreSsRegex = /s+/gi; const cityInFlorida = "Tallahassee"; cityInFlorida.match(oneOrMoreAsRegex); // ['a', 'a', 'a']; cityInFlorida.match(oneOrMoreSsRegex); // ['ss']; ``` **匹配連續出現零次或多次的字元** - 使用星號`*` ``` const zeroOrMoreOsRegex = /hi*/gi; const normalHi = "hi"; const happyHi = "hiiiiii"; const twoHis = "hiihii"; const bye = "bye"; normalHi.match(zeroOrMoreOsRegex); // ["hi"] happyHi.match(zeroOrMoreOsRegex); // ["hiiiiii"] twoHis.match(zeroOrMoreOsRegex); // ["hii", "hii"] bye.match(zeroOrMoreOsRegex); // null ``` **惰性匹配** - 符合要求的字串的最短部分 - 預設情況下，正則表達式是貪婪匹配（滿足要求的字串的最長部分） - 使用 `?` 字元進行惰性匹配 ``` const testString = "catastrophe"; const greedyRexex = /c[a-z]*t/gi; const lazyRegex = /c[a-z]*?t/gi; testString.match(greedyRexex); // ["catast"] testString.match(lazyRegex); // ["cat"] ``` **匹配起始字串** - 要測試字串開頭的字元，請使用插入符 `^`，但要在字元集之外 ``` const emmaAtFrontOfString = "Emma likes cats a lot."; const emmaNotAtFrontOfString = "The cats Emma likes are fluffy."; const startingStringRegex = /^Emma/; startingStringRegex.test(emmaAtFrontOfString); // true startingStringRegex.test(emmaNotAtFrontOfString); // false ``` **匹配結尾字串** - 在正則表達式末尾使用美元符號 `$` 來檢查字串末尾是否匹配 ``` const emmaAtBackOfString = "The cats do not like Emma"; const emmaNotAtBackOfString = "Emma loves the cats"; const startingStringRegex = /Emma$/; startingStringRegex.test(emmaAtBackOfString); // true startingStringRegex.test(emmaNotAtBackOfString); // false ``` **匹配所有字母和數字** - 使用 `\w` 簡寫 ``` const longHand = /[A-Za-z0-9_]+/; const shortHand = /\w+/; const numbers = "42"; const myFavoriteColor = "magenta"; longHand.test(numbers); // true shortHand.test(numbers); // true longHand.test(myFavoriteColor); // true shortHand.test(myFavoriteColor); // true ``` **匹配除字母和數字以外的所有內容** - 你可以使用 `\w` 的反義詞也就是 `\W` ``` const noAlphaNumericCharRegex = /\W/gi; const weirdCharacters = "!_$!!"; const alphaNumericCharacters = "ab283AD"; noAlphaNumericCharRegex.test(weirdCharacters); // true noAlphaNumericCharRegex.test(alphaNumericCharacters); // false ``` **匹配所有數字** - 你可以使用字元集 `[0-9]`，或者使用簡寫形式 `\d` ``` const digitsRegex = /\d/g; const stringWithDigits = "My cat eats $20.00 worth of food a week."; stringWithDigits.match(digitsRegex); // ["2", "0", "0", "0"] ``` **匹配所有非數字** - 你可以使用 `\d` 的反義詞也就是 `\D` ``` const nonDigitsRegex = /\D/g; const stringWithLetters = "101 degrees"; stringWithLetters.match(nonDigitsRegex); // [" ", "d", "e", "g", "r", "e", "e", "s"] ``` **匹配空格** - 使用 `\s` 匹配空格和換行 ``` const sentenceWithWhitespace = "I like cats!" var spaceRegex = /\s/g; whiteSpace.match(sentenceWithWhitespace); // [" ", " "] ``` **匹配非空格** - 你可以使用 `\s` 的反義詞也就是 `\S` ``` const sentenceWithWhitespace = "C a t" const nonWhiteSpaceRegex = /\S/g; sentenceWithWhitespace.match(nonWhiteSpaceRegex); // ["C", "a", "t"] ``` **匹配字元數** - 您可以使用 `{lowerBound, upperBound}` 在一行中指定特定數量的字元 ``` const regularHi = "hi"; const mediocreHi = "hiii"; const superExcitedHey = "heeeeyyyyy!!!"; const excitedRegex = /hi{1,4}/; excitedRegex.test(regularHi); // true excitedRegex.test(mediocreHi); // true excitedRegex.test(superExcitedHey); //false ``` **匹配最少的字元數** - 您可以使用 `{lowerBound,}` 要求滿足最少數量的字元 - 這稱為數量說明符 ``` const regularHi = "hi"; const mediocreHi = "hiii"; const superExcitedHey = "heeeeyyyyy!!!"; const excitedRegex = /hi{2,}/; excitedRegex.test(regularHi); // false excitedRegex.test(mediocreHi); // true excitedRegex.test(superExcitedHey); //false ``` **匹配準確的字元數** - 您可以使用 `{requiredCount}` 指定要求字元數 ``` const regularHi = "hi"; const bestHi = "hii"; const mediocreHi = "hiii"; const excitedRegex = /hi{2}/; excitedRegex.test(regularHi); // false excitedRegex.test(bestHi); // true excitedRegex.test(mediocreHi); //false ``` **某字元可以不出現** - 要允許某字元可以不出現，請使用 `?` ``` const britishSpelling = "colour"; const americanSpelling = "Color"; const languageRegex = /colou?r/i; languageRegex.test(britishSpelling); // true languageRegex.test(americanSpelling); // true ``` --- 以上是基礎用法＆範例，方便工作時可以查閱！
