Problem displaying a profile.

Hey guys! I'm having a problem rendering a users profile, avatar and badges. I think it may be a problem with the code in profile.html. Here's what I have:

<div id="profile">

    <img src="{{avatarUrl}}" alt="Avatar" id="avatar">

    <p><span>{{username}}</span></p>

    <ul>
        <li><span>{{badges}}</span> Badges earned</li>
        <li><span>{{javaScriptPoints}}</span> JavaScript points</li>
        <li><a href="/">search again</a></li>
    </ul>

</div>

And the code in renderer.js that iterates over the profile object:

function mergeValues(values, content) {
  //Cycle over the keys
  for(var key in values) {
    //Replace all {{key}} with value from the values object
    content = content.replace("{{" + key + "}}", values[key]);
  }
  //return merged content
  return content;

}

any suggestions?

Hi Nick,

I believe you will need to build a regular expression from a string in order to do this. You may also want to make the regex greedy so it will replace all occurrences of key instead of just the first occurrence. Here is a code example below. Hope it helps!

var regex = new Regex('{{' + key + '}}', 'g');
content = content.replace(regex, values[key]);
