1: Interpolation

Disadvantages: If your network speed is slow, or when data loading fails, interpolation will be rendered directly in the browser [js is disabled, and javascript errors will also cause this problem 】

html：

<section id="content">
<p id="Mustache">没有v-once, {{msg}}</p>
</section>

js:

 var vm = new Vue({
     el:"#content",
     data: {
       msg: "hello my lord"
     }
   });

result：

##2：v-once :By using the v-once command, perform one-time interpolation [When the data changes, the content at the interpolation will not continue to be updated]

html:

 <section id="content">
   插值:
   <p id="Mustache">{{msg}}</p>
   <p>v-once:当数据改变时，插值处的内容不会更新</p>
   <span v-once>{{msg}}</span>
 </section>

js:

 var vm = new Vue({
     el:"#content",
     data: {
       msg: "hello once"
     }
   });

result:

3, v-text and v-html

html:

 <section id="content">
   v-text：
   <span v-text="tipHtml"></span><br>
   原始 HTML:v-html指令
   <span v-html="tipHtml"></span>
 </section>

js:

var vm = new Vue({
    el:"#content",
    data: {
      tipHtml: "<b>小心点，明天</b>"
    }
  });

Result:

Summary: v-text: will also parse html tags into text, and v-html can parse html Label.
