如何基于特定单词截断数组内元素的字符串

Question

我是Java语言的新手，很难进行字符串操作我有一个这样的数组：

myArray = [{
cbID : "1" ,
cbCheckData : "{"request_id":"364165","final_decision":"FAIL","derived_Attribute_1":"PASS|Number of active MFI :0","derived_Attribute_4":"PASS|Total Exposure + Applied Amount :73307.0","derived_Attribute_3":"PASS|Number of Total Active Institutions :2","derived_Attribute_2":"FAIL|Overdue Amount:9828.0","derived_Attribute_5":"PASS|Write off amount:0.0","cbResponseMsg":"Final Decision:FAIL || Number of active MFI :0 || Total Exposure + Applied Amount :73307.0 || Number of Total Active Institutions :2 || FAILOver"}
]

这是我实际的数组结构：

我需要这样输出：

myArray = [{
cbID : "1" ,
cbCheckData : "{"request_id":"364165","final_decision":"FAIL","derived_Attribute_1":"PASS|Number of active MFI :0","derived_Attribute_4":"PASS|Total Exposure + Applied Amount :73307.0","derived_Attribute_3":"PASS|Number of Total Active Institutions :2","derived_Attribute_2":"FAIL|Overdue Amount:9828.0","derived_Attribute_5":"PASS|Write off amount:0.0"}
]

基本上，如果cbData包含单词，“ cbResponseMsg”及其后的单词，则需要截断字符串。

Answer 1

[好吧，首先将您的代码弄乱，在cbData：之后删除引号，然后在JSON对象的末尾插入另一个}。 （在下面的代码中更正）

Answer 2

如果cbResponseMsg内有cbData.cbResponseMsg，则会删除myArray。

Answer 3

由于cbResponseMsg是字符串化的JSON，因此可以在其上使用JSON.parse()，然后使用解构方法删除cbResponseMsg键。您可以使用.map()：
