note: These two instructions are only available after vue.js version 1.0

v-bind, the abbreviation of v-on

When building a single-page application (SPA), Vue.js will manage all templates, and the v- prefix is ​​not so important at this time. Therefore, Vue.js provides special abbreviations for the two most commonly used instructions v-bind and v-on:

Let me introduce the abbreviation of v-bind to you:

<!-- 完整语法 --> 
<a v-bind:href="url" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></a> 
<!-- 缩写 --> 
<a :href="url" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></a> 
<!-- 完整语法 --> 
<button v-bind:disabled="someDynamicCondition">Button</button> 
<!-- 缩写 --> 
<button :disabled="someDynamicCondition">Button</button>
Copy after login

v-on abbreviation:

<!-- 完整语法 --> 
<a v-on:click="doSomething"></a> 
<!-- 缩写 --> 
<a @click="doSomething"></a>
Copy after login
