title: onclick event to get email then mailto in html
body: <p>Hello I am pretty new in web development, I want to set up an hyperlink that if user click, it extract certain email address from a json file, then apply this address to the mailto method.
  my code is like this</p>
  
  <pre><code>&lt;div class="vipSpanTechnology spriteHover" ng-repeat="vip in vips"&gt;
      &lt;p&gt; &lt;b&gt;{{vip.name}}&lt;/b&gt;
          &lt;br&gt;{{vip.title}}&lt;br&gt;                   
          &lt;a sprite-class-indexed="email-addresses-" href="mailto:" onClick="this.href='mailto:{{vip.email}}'" target="_blank"&gt;&lt;/a&gt;
      &lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>but it can only apply mailto with the string {{vip.email}}, not the email string stored in {{vip.email}}. Is there any idea? thanks</p>
