vue babel-loader SyntaxError:“:click”语法上的意外标记

标签: vue.js vuejs2 jsx vue-component vue-loader

我使用这样的渲染函数:

.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 encoutners错误地说:click有意外的令牌。

.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-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会抛出如下错误:

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

正如@Bert Evans所说, 在重新阅读https://github.com/vuejs/babel-plugin-transform-vue-jsx的reademe文档之后,我发现我只是编写了代码而没有理解vue特定的jsx语法的语法。

正如文档所说:

  

请注意,使用JSX时几乎不支持所有内置Vue指令,唯一的例外是v-show,它可以与v-show={value}语法一起使用。在大多数情况下,有明显的程序化等价物,例如v-if只是一个三元表达式,而v-for只是一个array.map()表达式等。

     

Vue 2.0 JSX中的上述内容相当于:

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,我把代码改为

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>
    );
}

它有效!

尝试将html编写为字符串:

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

看起来你习惯了React,但它写的有点不同。
