html - JavaScript function in iframe src -

I'm new to javascript.

I have a JavaScript function, which returns me the name of the country. Now I have to put this value in IFAM's src. My Javascript function is as follows:

  & lt; Script type = "text / javascript" & gt; Var Country = $ ("# SCountry"). Val (); Function getCountry () {var country = $ ("# SCountry"). Val (); Return country; } & Lt; / Script & gt;   
 I am getting the value of the country but it can not be included in the source of IRAM. My iframe src is as follows:  
  src = 'https: //example.com/? Country = "javascript: getCountry ()" '  
 This is not working.   
 
 
 You give an ID for this kind of "content" iframe of your iframe) This is a pure JS The solution is:  
  document.getElementById ("iframe_id"). ContentDocument.getElementById ("destination_id"). InnerHTML = Country;   
 And your iframe tag can look like this: 
  & lt; Iframe src = 'https: //domain.com/' id = "iframe_id" & gt; `` And lieutenant Php:  
 JS:  
         
 with  `document.getElementById ('iframe_id'). Src = 'https://domain.com/?country=' + country; `  
 PHP in the iframe:    $ country = $ _POST [ "Country"]; Echo $ country; // This is the echo you can use where you want to show results
