Binding helper functions in Vue

There are two main ways to bind helper functions in Vue:

Method 1: Use the v-bind directive

The v-bind directive is used to bind data properties, which you can bind helper functions:

 <code class="html"><template> <button>My Button</button> </template> <script> export default { methods: { myFunction() { // 辅助函数逻辑} } } </script></code>

Method 2: Use v-on directive

v-on directive is used to bind event listeners, and you can also bind helper functions:

 <code class="html"><template> <button v-on:click="myFunction">My Button</button> </template> <script> export default { methods: { myFunction() { // 辅助函数逻辑} } } </script></code>

It should be noted that in Vue 2, the syntax of v-on directive is slightly different:

 <code class="html"><button v-on:click.native="myFunction">My Button</button></code>

Both methods can bind helper functions to elements of the component.
