Javascript return with string

Question

I have a JavaScript function that returns selected

function getage() {
    var selectedAge = selectedYear;
    var selectedAge = "";
    console.log(selectedAge);
    for (var key in selectedAge) { // run for every value in selectedAge
        console.log(key);
        if (selectedBirth.indexOf('20-' + key) > -1){
            if (selectedAge[key].length > 0) { // check if the subarray of selectedAge contains a value (if birth has selected age)
                selectedAge = selectedAge + age[key] + " selectedAge"; // add the age code as well as 'selected age' to return string
            } else {
                selectedAge = selectedAge + birth[key]; // adds only birth name
            }    
            selectedAge = selectedAge + "\n" + "\t";
        }
    }
    return selectedAge;
}

Any help would be appreciated!

If you want a new line...

in your HTML code (or strings in general), use \n
in your HTML output, use the   tag
in both your HTML code and its output, combine them (like  \n)

In html, either just use   where you would have wanted to use \n, or wrap every item in a display: block element like div or p or li.

You then have to make sure that your html is not escaped before inserting into the page, by using a function like jQuery's .html() or element.innerHTML = "...";.

EDIT:

try to add this var breakline = document.createElement("br"); in the code and add it to your selectedString

function getCoverage() {
  var selectedMarkers = selectedTowns;
  var selectedString = "";
  var breakline = document.createElement('br');
  selectedString.appendChild(breakline);
  console.log(selectedMarkers);
  for (var key in selectedMarkers) { // run for every value in selectedMarkers
    console.log(key);
    if (selectedRegions.indexOf('ZA-' + key) > -1) { // if current province is one of the selected provinces
      if (selectedMarkers[key].length > 0) { // check if the subarray of selectedMarkers contains a value (if province has selected town)
        selectedString = selectedString + province[key] + " selected towns"; // add the province code as well as 'selected towns' to return string
      } else {
        selectedString = selectedString + province[key]; // adds only province name (since regional coverage for this province)
      }    
      selectedString = selectedString
    }
  }

  return selectedString;
}

please use   instead of 

user5945910 Over a year ago

I've tried adding " ". Doesn't work as well. Just prints out " " with string.

user5945910 Over a year ago

@Gijsberts Hi thanks but still not working only prints out "[object HTMLBRElement]" where the line break is suppose to be.

Michał Miszczyszyn Over a year ago

BTW   is exactly the same as   in HTML5. According to the spec, / is ignored and the tag is simply treated as  .

John Slegers Over a year ago

@MichałMiszczyszyn : In XHTML, the / in   is mandatory. So, leaving it there both improves readability (as it's more obvious that the tag is self-closing) and improves backward compatibility with pre-HTML5 environments.

Another try, try to add the string in a element like a p or a h1 or something

function getCoverage() {
    var selectedMarkers = selectedTowns;
    var selectedString = "";
    console.log(selectedMarkers);
    for (var key in selectedMarkers) { // run for every value in selectedMarkers
        console.log(key);
        if (selectedRegions.indexOf('ZA-' + key) > -1) { // if current province is one of the selected provinces
            if (selectedMarkers[key].length > 0) { // check if the subarray of selectedMarkers contains a value (if province has selected town)
                selectedString = selectedString + province[key] + " selected towns"; // add the province code as well as 'selected towns' to return string
            } else {
                selectedString = selectedString + province[key]; // adds only province name (since regional coverage for this province)
            }    
            selectedString = selectedString;
        }
    }
    return "<p>" + selectedString + "</p>";
}
