## @vue/babel-sugar-v-on
|
||
|
|
|
||
|
|
Syntactic sugar for v-on in JSX.
|
||
|
|
|
||
|
|
### Babel Compatibility Notes
|
||
|
|
|
||
|
|
- This repo is only compatible with Babel 7.x, for 6.x please use [vuejs/babel-plugin-transform-vue-jsx](https://github.com/vuejs/babel-plugin-transform-vue-jsx)
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Install the dependencies:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
# for yarn:
|
||
|
|
yarn add @vue/babel-sugar-v-on
|
||
|
|
# for npm:
|
||
|
|
npm install @vue/babel-sugar-v-on --save
|
||
|
|
```
|
||
|
|
|
||
|
|
In your `.babelrc`:
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"plugins": ["@vue/babel-sugar-v-on"]
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
However it is recommended to use the [configurable preset](../babel-preset-jsx/README.md) instead.
|
||
|
|
|
||
|
|
### Details
|
||
|
|
|
||
|
|
This plugin adds v-on to the JSX and tries to mirror the same behaviour as in vue-template-compiler, with a few differences:
|
||
|
|
|
||
|
|
1. You should use underscore (`_`) instead of dot (`.`) for modifiers (`vOn:click_prevent={this.test}`)
|
||
|
|
2. It is recommended to use camelCase version of it (`vOn`) in JSX, but you can use kebab-case too (`v-on`).
|
||
|
|
|
||
|
|
```js
|
||
|
|
export default {
|
||
|
|
methods: {
|
||
|
|
test() {
|
||
|
|
console.log('Hello World')
|
||
|
|
},
|
||
|
|
},
|
||
|
|
render(h) {
|
||
|
|
return (
|
||
|
|
<div>
|
||
|
|
<a href="https://vuejs.org" vOn:click={this.test}>Vue</a>
|
||
|
|
</div>
|
||
|
|
)
|
||
|
|
},
|
||
|
|
}
|
||
|
|
```
