Question

目标：我想用破折号分割字符串，其中每个数组项都排除空格。

示例：

字符串->“ CL-目的地-机场税”

我已经尝试过：

var splitArray = section.split(/[-]+/);

预期：

splitAray [0] = "CN"
splitAray [1] = "Transit "
splitAray [2] = "Airport Tax"

实际：

splitAray [0] = "CN "
splitAray [1] = " Transit "
splitAray [2] = " Airport Tax"

如何轻松去除任何外部空间？

Answer 1

将map与trim一起使用：

const section = "CL - Destination - Airport Tax";
const splitArray = section.split(/[-]+/).map(s => s.trim());
console.log(splitArray);

ES5语法：

var section = "CL - Destination - Airport Tax";
var splitArray = section.split(/[-]+/).map(function(s) {
  return s.trim();
});
console.log(splitArray);

Answer 2

只需在破折号的两侧添加可选的空格：

var section = "CL - Destination - Airport Tax";
var splitArray = section.split(/\s*[-]\s*/);
console.log(splitArray);

Answer 3

这里的解决方案图功能将自动修剪数组的每个元素。


CREATE TABLE DB2.BOMHistory AS
SELECT 
    DB1.ProductInfo.ProductID
    DB1.ProductInfo.TimeCreated AS ProductCreated
    DB1.StationInfo.StationID
    DB1.StationInfo.BOM_used
    FROM DB1.ProductInfo
JOIN DB1.StationRecord
ON DB1.ProductInfo.ProductID = DB1.StationRecord.ProductID
JOIN DB1.StationInfo
ON DB1.StationRecord.StationID = DB1.StationInfo.StationID 
constraint PK_BOMHistory Primary Key (ProductID,StationID)
