I use render function like this:
.script.js
:
methods: {
handleClick(data){
console.log(data)
},
render(h, { node, data, store }) {
return (
<span>
<span>
<span>{node.label}</span>
</span>
<span style="float: right; margin-right: 20px">
<a href="javascript:;"
:attr="data.id" @click="handleClick">Edit{data.id}
</a>
</span>
</span>
);
}
}
But babel encoutners error saying the :click
has Unexpected token.

When i run gulp dist
, babel throws an error like follows:
Namespaced tags/attributes are not supported. JSX is not XML.\nFor attributes like xlink:href, use xlinkHref instead.
As @Bert Evans suggested, after re-reading the reademe docs of https://github.com/vuejs/babel-plugin-transform-vue-jsx, I figured out that i just wrote the code without understanding the syntax of vue-specific jsx syntax.
As the docs says:
Note that almost all built-in Vue directives are not supported when using JSX, the sole exception being
v-show
, which can be used with thev-show={value}
syntax. In most cases there are obvious programmatic equivalents, for examplev-if
is just a ternary expression, andv-for
is just anarray.map()
expression, etc.The equivalent of the above in Vue 2.0 JSX is:
render (h) {
return (
<div
// normal attributes or component props.
id="foo"
// DOM properties are prefixed with `domProps`
domPropsInnerHTML="bar"
// event listeners are prefixed with `on` or `nativeOn`
onClick={this.clickHandler}
nativeOnClick={this.nativeClickHandler}
// other special top-level properties
class={{ foo: true, bar: false }}
style={{ color: 'red', fontSize: '14px' }}
key="key"
ref="ref"
// assign the `ref` is used on elements/components with v-for
refInFor
slot="slot">
</div>
)
}
So, i changed my code to
render(h, {node,data,store}) {
const link = {
href: `/#/schema-type/${data.id}`
};
return (
<span>
<span>
<span>{node.label}</span>
</span>
<span>
<a href={link.href} target="_blank">edit</a>
</span>
</span>
);
}
And it works!
