[luci] How to call and pass arguments to lua function from a *template*

[Le Tran Dat]

Hi Nguyễn Hồng Quân,

Thanks for your suggestion, It's a good solution. I have thought about
this solution before but it's quite complicated one for small issue.

However, I managed to use another trick that is passing the section id
into lua using a button.

Here is my .lua file and my trick.
m = Map("chillistatus", "CoovaChilli Users")

-- User's Configuration

clients = m:section(TypedSection, "online", translate("Online"),
translate("This list gives an overview over currently online users and
their status."))
clients.reset = false
clients.submit = false
clients.template = "cbi/tblsection"
clients.anonymous = true

mac = clients:option(DummyValue, "mac", translate("MAC Address"))
ip = clients:option(DummyValue, "ip", translate("IP Address"))

kick = clients:option(Button, "_kick", translate("Kick"))
kick.inputstyle = "reset"

function kick.write(self, section)
      -- I will have the section id and I can use it like an index.
      -- Whenever I click a button on a row (tblsection template) then
I will get the index of that row.
end

Whenever I click *kick* button on a row (I am using tblsection
template) then I will get the index of that row. I can use it like an
index to find the mac address in the same row.

Many thanks for your help!
