Call lua script through XHR in htm, lua script location: /usr/lib/lua/luci/controller/admin/xxx.lua
xxx.htm:
1. Static call
var callPath='<%=luci.dispatcher.build_url("admin", "xxx", "dev_info")%>';
callPath=callPath+'/'+param1+'/'+param2; //If you need to pass parameters
XHR.get(callPath,null,function(x,rval)｛
......
｝
);
2. Dynamic call
var callPath='<%=luci.dispatcher.build_url("admin", "xxx", "dev_info",parameter)%>';
XHR.poll(5,callPath, null,function(x,callPath rval){
......}
);
The first parameter is the timing refresh time (unit: S)
The second parameter is the path generated by luci, where parameter is the parameter passed to lua
The third parameter is temporarily unknown, filling in null does not affect
The fourth is the callback function:
x: is an XHR object, generally not needed
rval: is the return value of the lua function (generally the value rval[0])
3. Trigger the submit submit call
<script>
document.getElementById("ID_INPUT_submit").value=paramt; //value value will be passed to lua
document.getElementById("ID_INPUT_submit").click(); //触发submit事件
</script>
<form style="display:none" method="post" action="<%=luci.dispatcher.build_url("admin", "xxx","dev_info")%>" enctype="multipart/form-data">
<input id="ID_INPUT_submit" name="getpackage" type="submit" \>
</form>
xxx.lua:
entry({"admin", "xxx", "dev_info"}, call("dev_info"), nil).leaf = true
Same for page methods 1,2:
--paramval: Receive the passed parameters, (there are two, write two input parameters)
function dev_info(paramval)
local function getDev(val)
......
return .....
end
luci.http.prepare_content("application/json")
luci.http.write('[')
luci.http.write_json(getDev(paramval))
luci.http.write(']')
end
Page method 3:
function dev_info()
local value=luci.http.formvalue("getpackage") -- get the passed down value, where getpackage is the name of the input
.......
end
