ee.String.split

根据正则表达式拆分字符串，返回字符串列表。

用法	返回
String.split(regex, flags)	列表

参数	类型	详细信息
此：string	字符串	要拆分的字符串。
regex	字符串	用于拆分的正则表达式。如果正则表达式为空字符串，则输入字符串会拆分为单个字符。
flags	字符串，默认值：""	一个字符串，用于指定正则表达式标志：'i'（忽略大小写）。

示例

代码编辑器 (JavaScript)

var s = ee.String('aBAbcD');
print(s.split('Ab'));  // ["aB","cD"]
// 'i' tells split to ignore case.
print(s.split('ab', 'i'));  // ["","","cD"]
// Split on 'b' or 'c'
print(s.split('[bc]', 'i'));  // ["a","A","","D"]
// Split on 'BA' or 'c'
print(s.split('(BA|c)'));  // ["a","b","D"]

var s = ee.String('a,b,cdee f,g');
// ["a",",","b",",","c","d","e","e"," ","f",",","g"]
print(s.split(''));

print(s.split(' '));  // ["a,b,cdee","f,g"]
print(s.split('[[:space:]]'));  // ["a,b,cdee","f,g"]

print(s.split(','));  // ["a","b","cdee f","g"]

print(s.split('ee'));  // ["a,b,cd"," f,g"]

// Split on any lower case letter.
print(s.split('[a-z]'));  // ["",",",",","","",""," ",","]

// ^ as the first character in [] excludes.
print(s.split('[^a-z]'));  // ["a","b","cdee","f","g"]

// Splitting on characters that are special to split.
var s = ee.String('a.b*c?d');
print(s.split('\\.'));  // ["a","b*c?d"]
print(s.split('[*]'));  // ["a.b","c?d"]
print(s.split('[?]'));  // ["a.b*c","d"]
