Mutation Error

The 'mutation-error' extension allows you to trigger an event when a request returns a >= 400 status code.

This is useful for things such as letting a child element (such as a button) inside a form know there was an error.

Example:

Copy 
 1h.Form(
 2    h.HxTriggerChildren(),
 3    h.HxMutationError(
 4        js.Alert("An error occurred"),
 5    ),
 6    h.Button(
 7        h.Type("submit"),
 8        h.Text("Submit"),
 9    ),
10)

It can also be used on children elements that do not make an xhr request, if you combine it with the TriggerChildren extension.
