【问题描述】:
我生成了一个包含大量嵌套数据的 JSON,其中一个在“操作”中称为“值”的属性用于动态生成的 html 表的每个输入的 v 模型中。最初,该属性设置为 0,输入设置为该值,但是当我更改输入中的值时,它不会反映在 json 中
JSON
[
{
"establishment_id":1,
"values":[
{
"capa_id":"A",
"operations":[
{
"operation_id":1,
"value":0
},
{
"operation_id":2,
"value":0
},
{
"operation_id":3,
"value":0
},
{
"operation_id":4,
"value":0
}
]
},
{
"capa_id":"B",
"operations":[
{
"operation_id":1,
"value":0
},
{
"operation_id":2,
"value":0
},
{
"operation_id":3,
"value":0
},
{
"operation_id":4,
"value":0
}
]
},
{
"capa_id":"C",
"operations":[
{
"operation_id":1,
"value":0
},
{
"operation_id":2,
"value":0
},
{
"operation_id":3,
"value":0
},
{
"operation_id":4,
"value":0
}
]
},
]
},
]
组件 设施、操作和 CAPA 是通过 Axios 从 API 获取的对象,这些数据用于生成表格和输入数据的 json

var establishments = Object.values(this.establishments)
var capas = Object.values(this.capas)

是否可以提供一个更简单的示例或更好地解释您要完成的工作?
