getNetworkOption

Function getNetworkOption is similar to getOption. It allows you to get the saved value of a network option. Uses kew as a promises polyfill.

Enqueue a script and add alchemy-options-client-scripts as its dependency. This will give you the global alchemyOptions variable.

For server-side use alch_get_network_option.

Example usage

alchemyOptions
    .getNetworkOption('my-network-option-id')
    .then(value => {
        //value is a JSON string like {"success":true,"data":42}
    });

getNetworkOption returns the kew defer, so you can deal with the promise later.

const myOption = alchemyOptions.getNetworkOption('my-network-option-id');

//later in the code
myOption.promise.then(value => {
    // do something with the value
});

If for some reason getNetworkOption fails, you can deal with it in the fail method. It can happen if the AJAX request errored or was aborted.

alchemyOptions
    .getNetworkOption('my-network-option')
    .then(value => {
        // value is a JSON string like {"success":true,"data":42}
    })
    .fail(response => {
        // failed to get the value
    });

More info on how to use promises can be found in the kew documentation.

Note on passing non-existent IDs

Most of the time getNetworkOption will be successful, even if you pass non-existent ID to it. Consider the following example:

alchemyOptions
    .getNetworkOption('some-non-existent-option')
    .then(value => {
        // value is a JSON string like {"success":true,"data":""}
    })

If you pass the option ID that doesn't exist, the call will still be successful, the data property will be an empty string.
