javascript - 拆分多个 Json Javascript

Question

我有像下面这样的 Json，

var json = [{"AVGDUR":1,"USERNAME":"usera","NAME":"name2","TOTALDOC":1}][{"AVGDUR":12,"USERNAME":"userb","NAME":"nameb","TOTALDOC":2}][{"AVGDUR":1.52,"USERNAME":"userc","NAME":"namec","TOTALDOC":617}][{"AVGDUR":2.41,"USERNAME":"userd","NAME":"named","TOTALDOC":167}][{"AVGDUR":1.65,"USERNAME":"usere","NAME":"namee","TOTALDOC":20}][{"AVGDUR":10,"USERNAME":"userf","NAME":"namef","TOTALDOC":1}][{"AVGDUR":0.46,"USERNAME":"userg","NAME":"nameg","TOTALDOC":143}]

现在我想将每个键分成 7 个 JSON 对象，如下所示。

var splitA =[{"AVGDUR":1,"USERNAME":"usera","NAME":"name2","TOTALDOC":1}]
var splitB = [{"AVGDUR":12,"USERNAME":"userb","NAME":"nameb","TOTALDOC":2}]
var splitC = [{"AVGDUR":1.52,"USERNAME":"userc","NAME":"namec","TOTALDOC":617}]
var splitD = [{"AVGDUR":2.41,"USERNAME":"userd","NAME":"named","TOTALDOC":167}]
var splitE = [{"AVGDUR":1.65,"USERNAME":"usere","NAME":"namee","TOTALDOC":20}]
var splitF = [{"AVGDUR":10,"USERNAME":"userf","NAME":"namef","TOTALDOC":1}]
var splitG = [{"AVGDUR":0.46,"USERNAME":"userg","NAME":"nameg","TOTALDOC":143}]

我该如何使用 JavaScript？

Answer 1

首先，这个 json 格式无效。如果不确定，您应该使用 json validator 来检查您的字符串。(例如 https://jsonlint.com/ )json 对象应该位于大括号 {} 内。每个属性:值对应该以逗号分隔。如果对象中有一个数组，则它应该位于方括号 [] 内。因此，在您的示例中，这是一个由对象组成的数组，您应该在开头有一个左括号，在最后有一个右括号。在大括号内，所有对象在每个右大括号 (}) 后都应有一个逗号 (,)。

然后你可以通过很多方式获取这些对象。例如，您可以逐个字符检查 json 字符串并跟踪每个左大括号和右大括号的索引，然后使用正确的索引获取子字符串。

但是，有 Json 解析器可以帮助您完成工作，但您的格式应该有效才能让它们工作。
