接口返回值Json数据如下：

{
"records": "25",
"page": "1",
"rows": [{"ORGANIZE_NAME": "222222222","APPLY_BATCH": "202009210002","TRACE_CODE_END": "001.14677805","TRACE_CODE_START": "001.14677805","REMAIN_NUM": 1,"AUDIT_ADVICE": "申请数量小于10000自动通过","ORGANIZE_CODE": "222222222","IS_EXPORTED": 0,"APPLY_USER_ID": "20200613182900852456","BOX_SIZE": 0,"TRACE_CODE_SUM": 1,"APPLY_STATUS": "1","CITY_NAME": "北京市市辖区","APPLY_TYPE_NAME": "质量码","SEND_ID": "20200921202401137352","APPLY_TIME": "2020-09-21","AUDIT_TIME": "2020-09-21"},{"ORGANIZE_NAME": "222222222","APPLY_BATCH": "202009210001","TRACE_CODE_END": "001.14677804","TRACE_CODE_START": "001.14677804","REMAIN_NUM": 1,"AUDIT_ADVICE": "申请数量小于10000自动通过","ORGANIZE_CODE": "222222222","IS_EXPORTED": 0,"APPLY_USER_ID": "20200613182900852456","BOX_SIZE": 0,"TRACE_CODE_SUM": 1,"APPLY_STATUS": "1","CITY_NAME": "北京市市辖区","APPLY_TYPE_NAME": "质量码","SEND_ID": "20200921202352826006","APPLY_TIME": "2020-09-21","AUDIT_TIME": "2020-09-21"}
]

}

需求：取出TRACE_CODE_START的值，并拆分，将001.后面的部分回写进环境变量，便于其他接口调用。

var jsonData = JSON.parse(responseBody);
var TRACE_CODE_START = jsonData.rows[0].TRACE_CODE_START;  // 质量码是001.14677805的格式，需要进行拆分
console.log(TRACE_CODE_START) // Ctrl + Alt + C 启动控制台
var A = TRACE_CODE_START.split(".")[0]  // 取出第一部分
var B = TRACE_CODE_START.split(".")[1]  // 取出第二部分
console.log(B)
pm.environment.set("TRACE_CODE_START", B);  // 将质量码回写到环境变量
