ee.String.split

：根據規則運算式分割字串，並傳回字串清單。

用量	傳回
String.split(regex, flags)	清單

引數	類型	詳細資料
這個：string	字串	要分割的字串。
regex	字串	用來分割的規則運算式。如果 regex 是空字串，輸入字串會分割成個別字元。
flags	字串，預設值為「""」	指定規則運算式標記的字串：「i」(不區分大小寫)。

範例

程式碼編輯器 (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"]
