javascript - 在常规 html 页面中使用 vue-multiselect.js

Question

我正在尝试在常规 html 页面中使用 vue-multiselect.js。它不工作。这是我的代码：

<script src="https://unpkg.com/vue-multiselect@2.1.0"></script>
<link rel="stylesheet" href="https://unpkg.com/vue-multiselect@2.1.0/dist/vue-multiselect.min.css">


<div>
  <label class="typo__label">Single select</label>
  <multiselect v-model="value" :options="options" :searchable="false" :close-on-select="false" :show-labels="false" placeholder="Pick a value"></multiselect>
  <pre class="language-json"><code>{{ value  }}</code></pre>
</div>

<script type="text/javascript">
import Multiselect from 'vue-multiselect'

export default {
components: {
    Multiselect
},
data () {
    return {
      value: '',
      options: ['Select option', 'options', 'selected', 'mulitple', 'label', 'searchable', 'clearOnSelect', 'hideSelected', 'maxHeight', 'allowEmpty', 'showLabels', 'onChange', 'touched']
        }
    }
}
</script>

这就是它在控制台中写的 -Uncaught SyntaxError: Unexpected identifier in line 12

你做错了。这是该概念的工作代码：

HTML：

<div id="app">
  <multiselect 
    v-model="value" 
    :options="options"
    :multiple="true"
    track-by="library"
    :custom-label="customLabel"
    >
  </multiselect>
  <pre>{{ value }}</pre>
</div>

Javascript：

new Vue({
    components: {
    Multiselect: window.VueMultiselect.default
    },
    data: {
    value: { language: 'JavaScript', library: 'Vue-Multiselect' },
    options: [
        {   language: 'JavaScript', library: 'Vue.js' },
      { language: 'JavaScript', library: 'Vue-Multiselect' },
      { language: 'JavaScript', library: 'Vuelidate' }
    ]
    },
  methods: {
    customLabel (option) {
      return `${option.library} - ${option.language}`
    }
  }
}).$mount('#app')
