3、split() 方法 JavaScript 中的 split() 方法允许我们将字符串拆分为数组。 它使我们能够在 JavaScript 中将字符串转换为数组。 下面是一个例子: const str = "JavaScript is Awesome";//convert to an array of single characters.str.split("");// returns ["J", "a", "v", "a", "S", "c"...
1^// Start at the beginning2[_a-zA-Z0-9-]// Define a group3+// One or more times4(// Group 15\.// a "real" dot6[_a-zA-Z0-9-]// Another group7+// One or more times8)// /* End group 1 */9*// Group optional or multiple times10@// The @ character11[a-zA-Z0-...
To split a string every N characters, call the `match()` method on the string, passing it the following regular expression `/.{1, N}g/`.
"1、2、3".split("、") == ["1", "2", "3"] "1、2、3".split(/(、)/g) == ["1", "、", "2", "、", "3"] "1、2、3".split(/(?=、)/g) == ["1", "、2", "、3"] "1、2、3".split(/(?!、)/g) == ["1、", "2、", "3"] "1、2、3".split(/(.*?
text.split(" ")// Split on spaces text.split("|")// Split on pipe Try it Yourself » If the separator is omitted, the returned array will contain the whole string in index [0]. If the separator is "", the returned array will be an array of single characters: ...

6.2 Strings that cause the line to go over 100 characters should not be written across multiple lines using string concatenation. Why? Broken strings are painful to work with and make code less searchable. // bad const errorMessage = 'This is a super long error that was thrown because \ ...

These two variables might contain the same series of characters but are different data types. The first is a string value, while the second is an instance of aStringobject. If you place these two values on either side of an equality (==) operator, JavaScript tries various evaluations of th...
Write a JavaScript function that accepts a string and a delimiter, and splits the string at the delimiter to return the latter portion. Write a JavaScript function that validates the delimiter input and returns a custom message if not found....
