How do I pass along variables with XMLHTTPRequest

Question

How do I send variables to the server with XMLHTTPRequest? Would I just add them to the end of the URL of the GET request, like ?variable1=?v

Answer 1

How about?

function callHttpService(url, params){
  // Assume params contains key/value request params
  let queryStrings = '';

  for(let key in params){
      queryStrings += `${key}=${params[key]}&`
    } 
 const fullUrl = `${url}?queryStrings`

  //make http request with fullUrl
}
