#Knockout Typeahead Binding

Simple knockout binding which wraps Twitter typeahead.js

##Installation

npm install knockout.typeahead

##Usage

Include in your bundle with browserify or webpack. You will need to have a loader configured for less files in order to get styling from the included stylesheet, or you can bring your own.

<input data-bind="value: myValue, typeahead: autocompleteMyValue" />

with a view model that looks like this:

function ViewModel() {
	this.myValue = ko.observable();
	this.autocompleteMyValue = '/my/server/url?value=%QUERY';
}

If the remote endpoint you are querying is returning a complex object instead of an array of suggestions, you can pass a remoteFilter parameter to the binding, a function on your view model which returns the portion of the response object containing the array of suggestions.

If you are returning complex objects as suggestions, pass a templateName into the binding to use a custom template.

<input data-bind="value: myValue, typeahead: autocompleteMyValue, remoteFilter: pluckResults, templateName: 'my-suggestion-template'" />

Clone the repository then npm i && npm run start to build the example.

##Additional Binding Options

• function mappingFunction: Function on your model which will map the suggestion data returned from your queries (e.g. so you can use computed observables and extenders in your template)
• string displayKey: Property name on complex object suggestion data which will be used to populate the hint/value of the typeahead input.
