Installing

Functions

eachComponent(components, fn, includeAll, path)

Calls fn(component) for each component in components, accounting for nested layout components. (Does not call for layout components themselves, unless includeAll is true).

The current data path of the element. Example: data.user.firstName

var utils = require('formio-utils');

utils.eachComponent(form.components, function(component) {
	// Do something...
})

getComponent(components, key)

Returns the component with the given key or undefined if not found.

var utils = require('formio-utils');

var component = utils.getComponent(form.components, 'myKey');

flattenComponents(components, includeAll)

Returns an key-value object where the keys are the keys for each component in components and each key points to the corresponding component. This includes nested components as well. Pass true for includeAll if you want to include layout components.

var utils = require('formio-utils');

var flattened = utils.flattenComponents(form.components);
console.log(flattened['myNestedComponent']);

isLayoutComponent(component)

Determine if a component is a layout component.

var utils = require('formio-utils');

var layoutComponent = utils.isLayoutComponent(form.components[0]);
console.log(layoutComponent);

getValue(submission, componentKey)

Get the value for a components API key, from the given submission. Recursively searches the submission for the key.

var utils = require('formio-utils');

var value = utils.getValue(submission, 'myComponent'); // The value or undefined.
