各种数据转换
1、字符串转换为数组
var
string =
'123,456,789'
;
var
stringResult = string.split(
','
);
console.log(stringResult)
//输出["123", "456", "789"]
var
string2 =
'abcdef'
var
string2Result = string2.split(
''
)
console.log(string2Result)
//输出['a','b','c','d','e','f']
string2.split(
","
).map(Number);
//输出[123,456,789]
JSON.parse(
"["
+ string +
"]"
);
//输出[123,456,789]
2、数组转换为字符串
var
array = [
'abc'
,
'def'
,
'hig'
]
var
arrayResult = array.join(
','
)
console.log(arrayResult)
// 输出"abc,def,hig"
array.toString()
//输出"abc,def,hig"
