// Lets pretend you want to have mail-address on your website but maybe want to protect it from being grabbed through bots
// This script turns a textelement into an useable link
// It removes spaces and replaces [at] with @ and [dot] with .
// Example: 
// <span class="mailconv">mail [at] codebryo [dot] com</span>
// Result:
// <a href="mailto:mail@codebryo.com">mail@codebryo.com</a>

var myFunctions = {
  mailConverter: function() {

      targets = document.querySelectorAll('.' + classname),

      var node = targets[i],
        text = node.innerText,
        elem = document.createElement('a');

      text = text.replace(/ /g, '');
      text = text.replace('[at]','@');
      text = text.replace('[dot]','.');
