Question

我想初始化我的数组值，如JSON数据，当我尝试不正确初始化时，在这里我的代码

我的JSON值

 [{"ShiftCode":"1","ShiftName":"BREAKFAST"},
 {"ShiftCode":"2","ShiftName":"LUNCH"}, 
 {"ShiftCode":"2","ShiftName":"LUNCH"},
 {"ShiftCode":"3","ShiftName":"DINNER"},
 {"ShiftCode":"3","ShiftName":"DINNER"}]

我尝试了以下

 shiftArr={'[[[{"ShiftCode":"1","ShiftName":"BREAKFAST"},{"ShiftCode":"2","ShiftName":"LUNCH"},{"ShiftCode":"2","ShiftName":"LUNCH"},{"ShiftCode":"3","ShiftName":"DINNER"},{"ShiftCode":"3","ShiftName":"DINNER"}]]]'};

它不起作用，我想进一步做些什么改变？

我假设您要将JSON数据解析为Lua表。如果是这样，请尝试以下代码：

J=[[
[{"ShiftCode":"1","ShiftName":"BREAKFAST"},
 {"ShiftCode":"2","ShiftName":"LUNCH"}, 
 {"ShiftCode":"2","ShiftName":"LUNCH"},
 {"ShiftCode":"3","ShiftName":"DINNER"},
 {"ShiftCode":"3","ShiftName":"DINNER"}] 
]]

L={}
n=0
for t in J:gmatch("%b{}") do
    n=n+1
    L[n]={}
    for k,v in t:gmatch('"(.-)":"(.-)"') do
        L[n][k]=v   
    end
end

使用JSON数据进行数组初始化 - lua
