I'm getting a bit confused about what I need to do here to retrieve my articles in scripts.js from /articles to display on my marker. I have done ample reading about AJAX and $.getJSON, but still wonder whether there is something wrong with my code, and have been spinning my wheels.

I have read some answers to questions that seem to have provided an answer. However, they seem to suggest using methods that may no longer be a suggested way to approach the Pset.

I have also tried modeling my getJSON request after code like this that has been reported to work.

Any tips would be greatly appreciated! Thank you.

Edit: Code runs now and markers open, with no errors reported in console. However, spinning loading wheel appears above marker when clicked, and shows no signs of loading anything.

My articles function in application.py:

def articles():
"""Look up articles for geo"""

    if not request.args.get("geo"): 
        raise RuntimeError("missing geo")

    articles = lookup(request.args.get("geo"))
    return jsonify(articles)

My relevant scripts.js code:

function addMarker(place)
  var latLng = new google.maps.LatLng(place.latitude, place.longitude);

  var marker = new google.maps.Marker({
    position: latLng,
    map: map,
    title: "place.place_name"+ "place.admin_name1"

var articles;
var contentString;

// get articles for place (https://cs50.stackexchange.com/questions/28726/cant-get-articles-on-my-marker-and-city-markers-are-persisting)
  $.getJSON("/articles"), {geo: place.postal_code},   function(data, textStatus, jqXHR){
    if (!$.isEmptyObject(articles)){
        var contentString = "<ul>";
        for (var i = 0; i < articles.length; i++)
            // write html as javascript in this function to display the articles.; use the plus symbol to concatenate strings
            contentString += "<li><a target='_NEW' href='" + articles[i].link +     "'>" + articles[i].title + "</a></li>";
        contentString += "</ul>";

  marker.addListener('click', function(){
  showInfo(marker, contentString);

    What do you see on the JavaScript console? If no error message, have you ensured the code is actually running?

  • @Blauelf, good idea. I updated the question with a picture of my console. Basically, the code does run except for my articles function. The map loads successfully, and it's searchable. When you click a search suggestion, markers appear on the map.

  • @Blauelf, after fixing this, I realized I did not declare articles and contentString as global variables. I did so, but I have encountered another issue. My marker window opens and shows it's currently loading, but nothing is appearing, even after several minutes.

Flask.url_for("/articles") is Python code, there is no Flask object in JavaScript. Try "/articles" without the Flask.url_for().
