User Guide

| Property | Type | Description | |-----------|-----------|-------------| | v-model | String | an empty or predefined string as search query| | onInputChange | Function | When the search query is changed, this function will be trigerred. The function should return an array of objects for the Component to render. It can also return a Promise instead of a set of objects. AJAX calls or delays can be addressed. | | onItemSelected | Function (optional)| When user selects (clicks or presses enter on an item), this function will be called | | options | Object | A set of options for customization of the component| | options.debounce | Integer | A delay in milliseconds between each "onInputChange" events. If unspecified, it will be ignored. Comes in handy for ajax requests. See examples. | |options.placeholder | string | A placeholder string for search (optional) | |options.inputClass | string | Override classnames given to the input text element (optional) |

  :onItemSelected="onSearchItemSelected"
  :onInputChange="onInputChange">
  <div slot="item" slot-scope="props" class="single-item">
    <template v-if="props.item.Icon && props.item.Icon.URL">
      <div class="image-wrap" :style="{'backgroundImage': 'url('+ props.item.Icon.URL + ')' }"></div>
    </template>
    <span class="name">{{props.item.Text}}</span>
  </div>
</suggestions>

export default {
  data () {
    return {
      searchQuery: '',
      selectedSearchItem: null,
      options: {}
    }
  },
  methods: {
    onInputChange (query) {
      if (query.trim().length === 0) {
        return null
      }
      const url = `http://api.duckduckgo.com/?q=${query}&format=json&pretty=1`
      return new Promise(resolve => {
        axios.get(url).then(response => {
          const items = []
          response.data.RelatedTopics.forEach((item) => {
            if (item.Text) {
              items.push(item)
            } else if (item.Topics && item.Topics.length > 0) {
              item.Topics.forEach(topic => {
                items.push(topic)
              })
