I have an array of products that I'm repeating over using ng-repeat and am using
<div ng-repeat="product in products | filter:by_colour">
to filter these products by colour. The filter is working but if the product name / description etc contains the colour then the product remains after the filter is applied.
How do I set the filter to only apply to the colour field of my array rather than every field?
Specify the property (i.e. colour) where you want the filter to be applied:
<div ng-repeat="product in products | filter:{ colour: by_colour }">
See the example on the filter page. Use an object, and set the color in the color property:
Search by color: <input type="text" ng-model="search.color">
<div ng-repeat="product in products | filter:search">
You can filter by an object with a property matching the objects you have to filter on it:
app.controller('FooCtrl', function($scope) {
$scope.products = [
{ id: 1, name: 'test', color: 'red' },
{ id: 2, name: 'bob', color: 'blue' }
/*... etc... */
];
});
<div ng-repeat="product in products | filter: { color: 'red' }">
This can of course be passed in by variable, as Mark Rajcok suggested.
Be careful with angular filter. If you want select specific value in field, you can't use filter.
Example:
app.controller('FooCtrl', function($scope) {
$scope.products = [
{ id: 1, name: 'test', color: 'lightblue' },
{ id: 2, name: 'bob', color: 'blue' }
/*... etc... */
];
});
<div ng-repeat="product in products | filter: { color: 'blue' }">
This will select both, because use something like substr
That means you want select product where "color" contains string "blue" and not where "color" is "blue".
If you want to filter on a grandchild (or deeper) of the given object, you can continue to build out your object hierarchy. For example, if you want to filter on 'thing.properties.title', you can do the following:
<div ng-repeat="thing in things | filter: { properties: { title: title_filter } }">
You can also filter on multiple properties of an object just by adding them to your filter object:
<div ng-repeat="thing in things | filter: { properties: { title: title_filter, id: id_filter } }">
Best way to do this is to use a function:
<div ng-repeat="product in products | filter: myFilter">
$scope.myFilter = function (item) {
return item === 'red' || item === 'blue';
};
Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.
