EmberJS - Query Parameters
Query parameters are specified on route driven controllers which appear to the right of the ? in a URL and are represented as optional key-value pairs.
For instance −
http://mysite.com/articles?sort=ASC&page=2
The above URL has the two query parameters; one is sort and the other is page which contains values ASC and 2 respectively.
The following table lists down the different ways of using query parameters −
| S.No. | Query Parameters & Description |
|---|---|
| 1 | Specifying Query Parameters
You can specify the query parameters on the route-driven controllers. |
| 2 | Opting Into a Full Transition
You can use optional queryParams configuration when a controller query parameter property changes to opt into a full transition. |
| 3 | Update URL with Replacestate Instead
It prevents from adding an item to your browser's history. |
| 4 | Map a Controller's Property to a Different Query Param Key
Mapping a controller query parameter property to a different query parameter key. |
| 5 | Default Values and Deserialization
Specifying the default values to the query parameter. |
| 6 | Sticky Query Param Values
In Ember, the query parameter values are sticky by default; so that any changes made to the query parameter, the new value of query parameter will be preserved by re-entering the route. |
