我需要以给定的格式传递数据。
rules : [{
name:null,
section:null,
data : [{head:null,value:null}]
}],
这就是我面临的问题。希望有人能帮我找出解决方案。给出了片段。我需要以上面给出的格式传递数据。如果 rules[] 里面需要另外一个数组也可以
data[] 中的 head 和 value 需要另一个数组。如果需要,这也可以。希望得到帮助。请帮助我找到解决方案。

最佳答案
我的方法基本上是根据您选择的选项更改 data[0].head 和 data[0].value 的类型。
例如,如果您选择 Rule,2012,则 data[0].head 将是一个 object with item 和 qty 作为它的项目。如果您选择 Act,1961,data[0].head 将是一个 array 数字(例如 ['1' , '2']) 和 data[0].value 将是一个 object with area_1 和 area_2 或 number 和 model 或所有四个项目。
查看并尝试代码片段以查看我添加/更改的代码。
(或者将您的代码与我的代码进行比较,您会看到变化。)
