Is there a built-in method in Angular for filtering or querying results as you type?
For example:
<input type='text' ng-model='query'>
<table>
<tr>
<td>Name</td>
<td># of Enrollments</td>
</tr>
<tr ng-repeat='c in courses | filter:query' onfilter='someStuff()'>
<td>{{c.name}}</td>
<td>{{c.enrollmentLength}}</td>
</tr>
</table>
If I type the letter "a" into the input text, I want it to trigger the someStuff() function.
To achieve this, utilize a timepiece integrated within your controller:
$scope.$watch('input', function(value) {
// This will trigger when the input is altered
});
Instead of using an expression, the filter in AngularJS can be used to call a function. Take a look at this example:
$scope.processQuery = function(course) {
// do some processing
};
<input type='text' ng-model='query'>
<table>
<tr>
<td>Name</td>
<td># of Enrollments</td>
</tr>
<tr ng-repeat='c in courses | filter:processQuery'>
<td>{{c.name}}</td>
<td>{{c.enrollmentLength}}</td>
</tr>
</table>
