mailto with HTML problems in Rails

Question

Here I need to send one mail with mailto(html) or mail_to(rails) function. But the problem is with mail body, how to attach the body with mailto function, I mean , when I click on this Mail link one Gmail client will open, so I need to get the imageURL in client body section.

<script type="text/javascript">
var **imageURL**;
function code (email) {

   imageURL = "https://chart.googleapis.com/chart?
   chs=150x150&cht=qr&chl=13&choe=UTF-
   8";
   $("#image_url").val(imageURL);
   $("#mailhere").html("<a class='btn btn-primary pull-left'
   href='mailto:"+email+"'>**Mail**</a>");
}


<div class="modal-footer" id="qr-code-footer">
 <a id="printme" href="#" class="btn btn-primary pull-left">Print</a>
  <div id="mailhere" class="span1">
  </div>  
</div>

Thank you

使用&body=Content

$("#mailhere").html("<a class='btn btn-primary pull-left' href='mailto:"+email+"&body=" + encodeURIComponent(imageURL) + "'>**Mail**</a>");
