使用split()方法:split()方法可以将字符串拆分为子字符串数组,根据指定的分隔符进行拆分。例如,如果要按逗号拆分字符串,可以使用以下代码: 代码语言:txt 复制 var str = "apple,banana,orange"; var arr = str.split(","); console.log(arr); 输出结果为:["apple", "banana", "orange"] 推荐的腾讯云相...
Use the String.split() method to split a string by newline, e.g. str.split(/\r?\n/). The split method will split the string on each occurrence of a newline character and will return an array containing the results. index.js const str = 'bobby\nhadz\r\ncom'; const result = st...
Thisis the first lineAndthisis the second 当然,有时你希望字符串中的反斜杠仅仅是反斜杠,而不是特殊代码。如果两个反斜杠相连,它们将合并在一起,结果字符串值中只会剩下一个。这就是字符串“换行字符的写法是“\n。”的表达方式: "A newline character is written like \"\\n\"." 字符串同样需要被...
// Extract a portion of the string and store it in a new variable var sliceString = newString.slice(newString.indexOf("l")+2,newString.length); alert(sliceString); // The split function creates a new array containing each value separated by a space stringArray = concatString.split(" ...
line" // 两行字符串分别写在两行上: `the newline character at the end of this line is included literally in this string` 请注意,当使用单引号界定字符串时,必须小心处理英语缩写和所有格,例如can’t和O’Reilly’s。由于撇号与单引号字符相同,必须使用反斜杠字符(\)来“转义”出现在单引号字符串中的...
split(/\D+/) // => ["","1","2","3"]: 以非数字为分隔符进行分割 3.4 布尔值 布尔值表示真或假,开或关,是或否。此类型仅有两个可能的值。保留字true和false评估为这两个值。 布尔值通常是您在 JavaScript 程序中进行比较的结果。例如:...
They are: match(), replace(), search(), and split(). MethodDescription exec() Executes a search for a match in a string and returns an array of information. It returns null on a mismatch. test() Tests for a match in a string and returns true or false. match() Returns an array ...
.split(RegExp)- 用正規表達式匹配的字元來分隔。 "a, b, c,d".split(/\s*,\s*/); // 可以匹配左右不定數目的空白,回傳["a","b","c","d"] 正規表達式方法 RegExp Method .exec(String)- 正規表達式主要的方法,跟字串的.match()有點類似,不過就算有g旗標一樣會回傳單一結果陣列。
