title: How could I return value with Vue.js
body: <p>I has worked with Vue for several days, and meet some problem.</p>
  
  <p>I use jQuery AJAX load data (text content) in template, title and description need to be ellipsis, I wrote the <code>methods</code> ↓</p>
  
  <pre><code>methods:{
                 titleELLIPSIS:function(){
                      var title = self.articleList.title;//AJAX data
                      var titleLength = title.length; 
                      var maxWidth = 15;
                      var newTitle = title.split("",maxWidth);
                      return title(function(ELLIPSIS){
                          if(titleLength&gt;maxWidth){
                              for(var j=newTitle.length-1;j&gt;0;j--){
                                  delete newTitle[j];
                                  var ELLIPSIS = self.innerHTML = newTitle.join('')+'...';
                                  if(newTitle.length&lt;=maxWidth){ break;}
                                  return ELLIPSIS;
                              }
                          }
                      })
  
                  }
  }
  </code></pre>
  
  <p>And my template is：</p>
  
  <pre><code>&lt;h2 class="ellipsis-2"&gt;{{titleELLIPSIS}}&lt;/h2&gt;
  </code></pre>
  
  <p>How could I return the ellipsis title in h2?</p>
  
  <p>Please give me some idea.</p>
  
  <p>By the way, the AJAX is success, because other data show correctly.</p>
