renderTemplate from DoAT Touchy, basic JS templating

gistfile1.js

// Render JavaScript template (from http://git.io/B7KxZg DoAT Touchy)
// 
// You can place your template in a script tag with type other than "text/javascript"
// such as "text/html", like this:
// <script type="text/html" id="item-template">
// <li id="{{id}}">
//   <p>{{content}}</p>
// </li>
// You'd then render your template like this:
// var itemTemplate = document.getElementById('item-template').innerHTML;
// renderTemplate( itemTemplate, {
//   id : "item1",
//   content : "lorem ipsum dolor sit amet …"
// });

var renderTemplate = function(str, attrArr){
  if (!attrArr){return str}
  for (var key in attrArr){
    var keyRegex = new RegExp("{"+key+"}", "g");
    var value = attrArr[key];
    str = str.replace(keyRegex, value);
  }
  return str;
};

var renderTemplate = function(tpl, dict) {
    if (!dict) return tpl;
    return tpl.replace(/\{([\w.\-]+)\}/g, function(key, submatch) {
        return ({}).hasOwnProperty.call(dict, submatch) ? dict[submatch] : key;
    });
};
