How to use $timeout function in Client controller to send data to server side on portal

[Priya75]

Hi All, 

I am trying to send from the client controller to the server side, I am getting the data on change of field which is a  choice list on portal which is a HTML Field.

So i tried without $timeout the data is not coming properly so i am using $timeout. i have used console to check if value is correct on client side. I am getting error as  "cann't read properties of undefined reading get "

c.hostname= function(){
var host;
$timeout(function(){

host=c.hostname;
this.server.get({
          action: 'getvaluefromserver',;
          name:host;
        
            }).then(function(response) {
c.cloudedata=response.data.cloudpro;
console.log("data"+response.data.cloudpro)
             
          
          })
        }, 5000); // 5000 milliseconds = 5 seconds
    }
