javascript - 另一个数组中的数组

Question

问题陈述

我正在尝试用这个数组中的另一个数组创建一个数组，但它对我不起作用。

这是我写的:

var arr = '{"project":['
                    + '{"id":"01","name":"project1","activity":['
                    + '{"num":"001","time":"7","desc":"desc","stam":['
                    + ' "pre":"005","pre2":"002"]}'
                    + '{"num":"002","time":"6","desc":"desc"}'
                    + '{"num":"003","time":"5","desc":"desc"}'
                    + '{"num":"004","time":"4","desc":"desc"}'
                    + '{"num":"005","time":"3","desc":"desc"}]}]}';

您的 JSON 看起来已损坏。您可以使用多个在线编辑器和验证器来验证 JSON 字符串。 editor和 validator就像许多其他人的例子一样。你也可以看看here .

• , 数组元素之间缺失
• stam 属性看起来更像是一个对象而不是数组

它应该是这样的:

{"project":[
            {"id":"01","name":"project1","activity":
              [
                {"num":"001","time":"7","desc":"desc","stam":{
                  "pre":"005",
                  "pre2":"002"
                }
                },
                {"num":"002","time":"6","desc":"desc"},
                {"num":"003","time":"5","desc":"desc"},
                {"num":"004","time":"4","desc":"desc"},
                {"num":"005","time":"3","desc":"desc"}
              ]
            }
          ]
}
