vue babel-loader SyntaxError: Unexpected token on ":click" syntax

Question

我这样使用渲染函数：

.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>
            );
        }
}

但是 babel 遇到错误说 :click 有意外的标记。

.vue:

<template src="./template.html"></template>
<script src="./script.js"></script>

package.json:

"vue": "^2.2.6"
"vue-router": "^2.4.0"
"element-ui": "^1.2.8",
"babel-core": "^6.24.0",
"babel-loader": "^6.4.1",
"babel-plugin-transform-vue-jsx": "^3.4.2",
"vue-loader": "^11.3.4",
"webpack": "^2.3.1",

webpack:

{
    test: /\.vue$/,
    loader: `vue-loader`,
    options: {
        loaders: {
            js: 'babel-loader'
        }
    }
},
{
    test: /\.js$/,
    loader: `babel-loader`,
    exclude: /(node_modules)/
}

.babelrc:

{
    "presets": [
        ["es2015", { "modules": false }], "stage-1", "stage-2", "stage-3"
    ],
    "plugins": [
        ["transform-vue-jsx"],
        ["transform-object-assign"],
        ["component", [{
            "libraryName": "element-ui",
            "styleLibraryName": "theme-default"
        }]]
    ]
}

当我运行gulp dist时，babel抛出如下错误：

Namespaced tags/attributes are not supported. JSX is not XML.\nFor attributes like xlink:href, use xlinkHref instead.

Answer 1

正如@Bert Evans 所建议的，在重新阅读 https://github.com/vuejs/babel-plugin-transform-vue-jsx 的自述文档后，我发现我只是在不理解 vue 特定 jsx 语法的语法的情况下编写代码。

正如文档所说：

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 the v-show={value} syntax. In most cases there are obvious programmatic equivalents, for example v-if is just a ternary expression, and v-for is just an array.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>
      )
    }

所以，我将代码更改为

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>
    );
}

而且有效！

Answer 2

尝试将您的 html 写成字符串：

Vue.component('my-component', {
    template: '<div>A custom component!</div>'
});

看起来你习惯了React，但是写的有点不一样

vue babel-loader SyntaxError: Unexpected token on ":click" syntax

vue babel-loader SyntaxError: Unexpected token on ":click" syntax

jsx

vue.js

vue-component

vue-loader

vuejs2
