3.str.slice(a,b); 截取 从a开始到b-1结束; slice() 'JavaScript'.slice(0, 4) // "Java" 1. 如果省略第二个参数,则表示子字符串一直到原字符串结束。 'JavaScript'.slice(4) // "Script" 1. 如果参数是负值,表示从结尾开始倒数计算的位置,即该负值加上字符串长度。 'JavaScript'.slice(-6) /...
slice 语法 string.slice(start,end) 参数值 返回值 提取所有字符串: var str="Hello world!"; var n=str.slice(0); 以上实例输出结果: Hello world! 从字符串的第3个位置提取字符串片段: var str="Hello world!"; var n=str.slice(3); 以上实例输出结果: lo world! 从字符串的第3个位置提取8个字...
首先明确一点，Rust 核心语言中只有一种字符串类型，即字符串切片（string slice）str，它本质上是满足 ...
Theslice()method returns the extracted part in a new string. Theslice()method does not change the original string. The start and end parameters specifies the part of the string to extract. The first position is 0, the second is 1, ... ...

Thesubstring()method does not change the original string. If start is greater than end, arguments are swapped: (4, 1) = (1, 4). Start or end values less than 0, are treated as 0. See Also: The split() Method The slice() Method ...
In this case the length is 5 and 'o' is at index 4. Put another way, the chars in a string are at indexes 0, 1, 2, .. up through length-1. We'll use the index numbers to slice and dice strings with substring() in the next section. ...
