Input field filters not working in AngularJS

I have successfully implemented almost all types of filters in this fiddle:



<div data-ng-app='' data-ng-init="vehicles=[
{type:'car',color:'red'},
{type:'bike',color:'black'}]">
<h1>
AngularJS <a href='http://www.w3schools.com/angular/angular_filters.asp'>
Filters Example</a>
</h1>

<p>Enter text
<input type='text' data-ng-model='abc' />
</p>
<p>The text you entered is
<br/> <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_uppercase'>Upper case</a> {{ abc | uppercase }}
<br/><a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_lowercase'>Lower case</a> {{ abc | lowercase }}</p>Enter amount
<input type='number' data-ng-model='num1' />
<p>The <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_currency'>amount</a> you entered is
<br/>{{ num1 | currency }}</p> <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_orderby'> Directives Filter example</a>

<br/>Vehicles filtered by type:
<ul data-ng-repeat="v in vehicles | orderBy:'type'">
<li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li>
</ul>
<br/>Vehicles <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_input'>filtered by user input:</a>

<br/>
<input type="text" ng-model='test' />
<ul data-ng-repeat="v in vehicles | filter: 'test' | orderBy:'type'">
<li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li>
</ul>
</div>





Everything is working except input filters.

This is how I'm seeing it now:

no output


Why is the array not printed and filtered by user input?

Answer Source

Remove the single quotes from 'test' passed to the filter. Since it is not a string, its a model and it should be passed directly to the filter.

<ul data-ng-repeat="v in vehicles | filter: test | orderBy:'type'">
    <li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li>
</ul>

The above code will work.
