<p>One way would be to shift your class assignment to a method:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>new Vue({
  el: "#app",
  data: {
  	myValues: [
    	  {status: 'Online'},
          {status: 'Updating'}
    ]
  },
  methods: {
  assignedClasses(status) {
      var classToAssign; 
      if(status === 'Online'){
      	classToAssign = 'badge-success';
      }
      else if(status === 'Updating') {
      	classToAssign = 'badge-warning';
      }
      else {
      	classToAssign = 'badge-danger';
      }
      
      return classToAssign;
    }
  }
})</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://unpkg.com/bootstrap@4.1.1/dist/css/bootstrap.min.css" rel="stylesheet"/&gt;
&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"&gt;&lt;/script&gt;

&lt;div id="app"&gt;
  &lt;div v-for="(obj, index) in myValues" :key="index"&gt;
    &lt;span class="badge badge-pill" :class="assignedClasses(obj.status)"&gt;{{obj.status}}&lt;/span&gt;
  &lt;/div&gt; 
&lt;/div&gt;</code></pre>
</div>
</div>
</p>


entityMap|blocks|key|5snh3|text|<span+v-if="obj.status+===+'Online'"+class="badge-success">

</span>

<span+v-if="obj.status+===+'Updating'"+class="badge-warning">
+++{{obj.status}}
</span>

<span+v-if="obj.status+!==+'Updating'+&&+obj.status+!==+'Online'"+class="badge-default">
++++{{obj.status}}
</span>|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|d95e6|您可以基于status属性有条件地呈现。|unstyled|4qfuj|另一种方法是切换你的类的大小写：|2rf5n|new+Vue({

++++++++++case+'Updating':
+++++++++++++++return+'badge-warning';
++++++++++default:
+++++++++++++++return+'badge-default'
++++++}
++++}
++}
})|3niou|然后在你的模板中，你可以这样做：|c66pf|<span+:class="getBadgeClass(obj.status)">{{obj.status}}</span>|dk99b^0|0|0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|Q|9|@]|A|@]|B|$C|D]]|$2|E|4|F|6|G|8|R|9|@]|A|@]|B|$]]|$2|H|4|I|6|G|8|S|9|@]|A|@]|B|$]]|$2|J|4|K|6|7|8|T|9|@]|A|@]|B|$C|D]]|$2|L|4|M|6|G|8|U|9|@]|A|@]|B|$]]|$2|N|4|O|6|7|8|V|9|@]|A|@]|B|$C|D]]|$2|P|4|-4|6|G|8|W|9|@]|A|@]|B|$]]]]

<pre><code>&lt;span v-if="obj.status === 'Online'" class="badge-success"&gt;
   {{obj.status}}
&lt;/span&gt;

&lt;span v-if="obj.status === 'Updating'" class="badge-warning"&gt;
   {{obj.status}}
&lt;/span&gt;

&lt;span v-if="obj.status !== 'Updating' &amp;&amp; obj.status !== 'Online'" class="badge-default"&gt;
    {{obj.status}}
&lt;/span&gt;
</code></pre>

<p>You can conditionally render based on the status property.</p>

<p>The other way is to switch-case your class:</p>

<pre><code>new Vue({
  el: "#app",
  data: {
    obj: {
       status: 'Online'
    }
  },
  methods: {
  getBadgeClass(status) {
      switch(status) {
          case 'Online':
               return 'badge-success';
          case 'Updating':
               return 'badge-warning';
          default:
               return 'badge-default'
      }
    }
  }
})
</code></pre>

<p>and then in your template you can do this:</p>

<pre><code>&lt;span :class="getBadgeClass(obj.status)"&gt;{{obj.status}}&lt;/span&gt;
</code></pre>


entityMap|blocks|key|fr12r|text|添加多个条件的一种方法可能如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|7mic9|<span+
:class="[{'badge-success':obj.status+===+'Online',+'badge-warning':obj.status+===+'Updating',+'badge-danger':obj.status+===+'Failed'},'badge+badge-pill']"

</span>|code-block|syntax|javascript|dhcjf^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|I|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|J|9|@]|A|@]|B|$F|G]]|$2|H|4|-4|6|7|8|K|9|@]|A|@]|B|$]]]]

<p>One way to add multiple conditions can be like this </p>

<pre><code>&lt;span 
:class="[{'badge-success':obj.status === 'Online', 'badge-warning':obj.status === 'Updating', 'badge-danger':obj.status === 'Failed'},'badge badge-pill']"
&gt;
{{obj.status}}
&lt;/span&gt;
</code></pre>


<p>I have the following Vue.js bound HTML:</p>

<pre><code>&lt;span :class="[obj.status === 'Online' ? 'badge-success' : 'badge-danger', 'badge badge-pill']"&gt;{{obj.status}}&lt;/span&gt;
</code></pre>

<p>I want to add another variant:</p>

<p>if <code>obj.status === 'Updating'</code> then the class should be <code>badge-warning</code>.</p>

<p>What is the best way to achieve this efficiently? I think I can add another ternary in the existing one but it will look messy.</p>
