vue-dawa v1.2.5

vue-dawa

This component allows you to create an address-autocomplete using Danmarks Adressers WEB API in Vue 2 applications.

It relies heavily on https://github.com/DanmarksAdresser/dawa-autocomplete2, but uses the axios library instead of fetch for making requests and it is fully "vue-ified".

Demo

Installation

npm install --save vue-dawa

Usage

Make sure to import the component:

  import VueDawa from 'vue-dawa'

Add it to your components' components:

 export default {
  components: {
    VueDawa
  }
}

In your template:

<vue-dawa @select="selectItem($event, 'yourAddressObject')"
  :val="yourAddressObject.oneLineAddress"
  :showMax="5"
  placeholder="Your Placeholder"
  containerId="your-container"
  fieldId="your-field-id"
  fieldName="your-field-name">
  <label slot="label-top" for="field-2">Your label</label>
</vue-dawa>

In your component's data, you will need to provide yourAddressObject.

  data () {
    yourAddressObject: {
      oneLineAddress: ''
    }
  }

You will also need to define a method for modifying the selected address to your needs - if that is desired.

// here the event payload is of the type "adresse"
translateData (address) {
  if (!address || !address.data) {
    return
  }
  return {
    id: address.data.id,
    street: address.data.vejnavn,
    streetNumber: address.data.husnr,
    floor: address.data.etage,
    door: address.data.dør,
    zipCode: address.data.postnr,
    city: address.data.postnrnavn,
    oneLineAddress: address.tekst
  }
}

If you will create multiple fields in the same component, you might want to handle the select event in a manner that will allow you to update whichever address object without writing custom handlers for each. A quick example:

  // handle the select event emitted by vue-dawa
  selectItem (payload, objectName) {
   this.$set(this, objectName, this.translateData(payload))
  } 

Events

Props

Default options prop

{
  params: {},
  minLength: 2, // would leave this alone if I were you, it can lead to wonky behavior.
  retryDelay: 500,
  type: 'adresse',
  baseUrl: 'https://dawa.aws.dk',
  adgangsadresserOnly: false,
  stormodtagerpostnumre: true,
  supplerendebynavn: true,
  fuzzy: true,
}

Overflow:hidden nuissance

If vue-dawa is placed in a container (or descendant of a container) with overflow: hidden, the list of results will be cut off. There is no easy or nice fix for this, unfortunately.

What you CAN do, is leverage the listHeightUpdated event, which will pass to you the height of the list of results.

You can use this height to compute a min-height property on the container in question or child of it, and give it a transition on the height for a smoother change. It's not flawless, but it will allow you to use the component in a container with overflow: hidden.

Styling

You can require the default style:

require('vue-dawa/dist/vue-dawa.min.css')

or customize the css yourself. Remember you can add custom classes to all the elements of the componets.

For the results list, you can also provide styling options via the resultsListStyle prop. For instance, if you want to control the scroll of the list, this property's value could be:

<vue-dawa 
... other props
:resultsListStyle = "{
  maxHeight: '200px',
  overflowY: 'auto',
  overFlowX: 'hidden'
}"/>

Here's a starting point for tweaking the default css.

    .autocomplete-container {
        /* relative position for at de absolut positionerede forslag får korrekt placering.*/
        position: relative;
        width: 100%;
        max-width: 30em;
    }

    .autocomplete-container input {
        /* Både input og forslag får samme bredde som omkringliggende DIV */
        width: 100%;
        box-sizing: border-box;
        margin-bottom: 5px;
    }

    .dawa-autocomplete-suggestions {
        position: absolute;
        z-index: 9999;
        width: 100%;
        margin: 0.15em 0 0 0;
        padding: 0;
        text-align: left;
        border-radius: 0.3125em;
        background: #fcfcfc;
        box-shadow: 0 0.0625em 0.15625em rgba(0,0,0,.15);
        box-sizing: border-box;
    }

    .dawa-autocomplete-suggestions .dawa-autocomplete-suggestion {
        margin: 0;
        list-style: none;
        cursor: pointer;
        padding: 0.4em 0.6em;
        color: #333;
        border: 0.0625em solid #ddd;
        border-bottom-width: 0;
    }

    .dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:first-child {
        border-top-left-radius: inherit;
        border-top-right-radius: inherit;
    }

    .dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:last-child {
        border-bottom-left-radius: inherit;
        border-bottom-right-radius: inherit;
        border-bottom-width: 0.0625em;
    }

    .dawa-autocomplete-suggestions .dawa-autocomplete-suggestion.active,
    .dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:hover {
        background: #f0f0f0;
        color: #333;
    }
