@morsedigital/select-filter v1.0.1

select-filter

Allows a select to call api to filter results in another select.L0

Install into project

yarn add @morsedigital/select-filter

Set up your HTML like so:

<select data-select-filter="second-select" data-select-filter-api="my/api/path" id="first-select">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
</select>

<select id="second-select"> </select>

'data-select-filter' is id of the select you want updated

'data-select-filter-api' is the api path to where you are going to pull the data from.

In javascript add the following way:

import SelectFilter from "@morsedigital/select-filter";

(() => {
  SelectFilter();
})();

Then when the select is changes it will hit the api + value. So in this example if 'Option 1' is selected the a request is sent to 'my/api/path/1'.

The response should be as json like so:

[
  {
    "title": "Option",
    "value": "some value"
  },
  {
    "title": "Another Option",
    "value": "another value"
  }
]

and the select will be updated like so:

<select id="second-select">
  <option value="some value">Option</option>
  <option value="another value">Another Option</option>
</select>

You can also change the way the api is called.

If you prefer a query string:

import SelectFilter from "@morsedigital/select-filter";

(() => {
  SelectFilter({ query: true });
})();

Then when the select is changes it would call 'my/api/path?value=1'.

Or if you would prefer to POST the data for the following:

import SelectFilter from "@morsedigital/select-filter";

(() => {
  SelectFilter(
    { query: false },
    {
      method: "POST"
      //... other fetch options
      // see https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch
    }
  );
})();

Then when the select is changes it would call 'my/api/path' with a json body of { value: 1 }
