Archived

It was fun while it lasted, but we have to stop maintaining these repositories. We haven't used these projects for quite some time and maintaining them is becoming harder to do.

You deserve better, and for that reason we've decided to archive some repositories, which includes this one.

Feel free to fork and alter the repositories, and go forth making awesome stuff.

aurelia-autocomplete

An autocomplete component for the aurelia framework.

Setup

Installation

jspm install aurelia-autocomplete

Configure

Simply register autocomplete as a plugin in main.js.

Usage

simple

<auto-complete resource="language"></auto-complete>

or if you have an array with items and thus would not need to perform a request

export class Page {
  languages = [ /* languages */ ];
}

<auto-complete items.bind="languages"></auto-complete>

extended

export class MyViewModel {

  results     = [];
  attributes  = ['productName', 'barcode'];
  customLabel = product => product.name + product.barcode;
  value       = 'banana';
  productCriteria = {
    stock: {'>': 0}
  };
  defaultProduct = {
    productName: 'No product',
    productCategory   : 'none'
  };

  constructor() {
    product = this.defaultProduct;
  }

  resultsChanged(products) {
    // select the first product that has the name 'banana'. If cannot be found
    // then select the first product in the results.
    this.selected = products.find(product => product.name === 'banana') || products[0];

    // always show the no product option
    this.results = this.results.concat([this.defaultProduct]);
  }

  productSort(products) {
    products.sort((a, b) => a.price > b.price;
  }

}

  <h4>${product.productName} ${product.productCategory}</h4>

  <auto-complete
    resource="product"
    selected.bind="selected"
    value.two-way="value"
    result.two-way="value"
    attribute.bind="attributes"
    results.bind="results"
    limit="5"
    endpoint="product-api"
    sort.bind="productSort"

By default it makes sure to not return more items than the limit specifies.

get regex()
