Is it possible to convert a key in object? I would like to simplify this code:

This works:

for key, data in pairs(DBButtonOptions[self.value]) do
    if key == "widgetframe1" then
        widgetframe1:SetText(data)
        widgetframe1:SetDisabled(enable)
    elseif key == "widgetframe2" then
        widgetframe2:SetText(data)
        widgetframe2:SetDisabled(enable)
    elseif key == "widgetframe3" then
        widgetframe3:SetText(data)
        widgetframe3:SetDisabled(enable)
    elseif key == "widgetframe4" then
        widgetframe4:SetText(data)
        widgetframe4:SetDisabled(enable)
    elseif key == "widgetframe5" then
        widgetframe5:SetText(data)
        widgetframe5:SetDisabled(enable)
    end
end

This does not work:

for key, data in pairs(DBButtonOptions[self.value]) do
    key:SetText(data)
    key:SetDisabled(enable)
end

This works but error (Attempt to index local key):

for key, data in pairs(DBButtonOptions[self.value]) do local key = _G[key] key:SetText(data) key:SetDisabled(enable) end

    can you try using a different name for your local variable and use the last one, i.e. `local control = _G[key]`? Also what do you mean by it works but you get an error? Is it possible there is a key that isn't a control with SetText and SetDisabled functions? – Jason Goemaat May 28 '18 at 22:26

The problem seems to take key like local variable. check this post

I tried this snippet and it works fine

storeFn = _G
storeFn.Gn = {} -- limit iteration of loop "for" and don't get errors
storeFn.Gn.first = function(val) print("test first! "..val) end
storeFn.Gn.second= function(val) print("test second! "..val) end

for k, v in pairs(storeFn.Gn) do
     print( assert (loadstring('return '..'storeFn.Gn.'..k..'(...)')) (math.random()) )
end

Only have be careful with memory leaks

storeFn.Gn = nil
for k,_ in pairs(storeFn) do print(k) end -- restart to original _G

Also can use _G.Fn={} and after destroy it _G.Fn=nil
