#Usage

<ng-email-list ng-model="emails"></ng-email-list>

Optional Usage:

<ng-email-list ng-model="model" rejected="rejects" repeat="repeats"></ng-email-list>

If you are using angular 1.3 or greater you can debounce the input:

<ng-email-list ng-model="emails" ng-model-options="{debounce : 1000}"></ng-email-list>

NOTE: If you want your model value to be updated even on invalid input, set the ng-model-options="{allowInvaid: true}"

<ng-email-list ng-model="emails" ng-model-options="{allowInvalid : true}"></ng-email-list>

##Model

Model will be set with an array of valid email address. If the repeat option is specified, it will not contain repeats.

##Rejected (Optional)

An array of invalid email addresses. Perfect for displaying more useful error messages.

##Repeat (Optional) or norepeat

An array of repeated email addresses. Perfect for displaying more useful error messages. WARNING: This feature is incompatible with IE8 or below.

If you do not want an array of repeated emails you can set norepeats.

<ng-email-list norepeat ng-model="emails"></ng-email-list>

<ng-email-list ng-model="emails" repeat="initializedArray"></ng-email-list>

<ng-email-list ng-model="emails" repeat="undefinedVar" norepeat></ng-email-list>

NOTE: arrayOfRepeats must be an empty arry initailized before the directive or you will need to include norepeat.

##Brackets (Optional)

Parser removes all occurrences of < and > before validation.

<ng-email-list ng-model="emails" brackets></ng-email-list>

##Form Validity

If you use the email-list with angulars form validity you get access to the following options: email, repeat, and invalid.

The email error is set if there are one or more invalid emails.

The repeat error is set if there are one or repeated emails. This error will only be set if you set the repeat property. WARNING: This feature is incompatible with IE8 or below.

The invalid error is set if there are invalid or repeated emails. Repeated emails are only check if the repeated property is set.

###Form Validity Example

You can display human friendly error messages in the following manner:

<form name="myForm">
  <email-list name="list" ng-model="emails" rejected="rejects" repeat="repeats"></email-list>
  <div ng-show="inviteForm.list.$error.emailList">
      <p>The email list is invalid!</p>
  </div>
  <div ng-show="inviteForm.list.$error.email">
      <p ng-show="rejects.length === 1">The following email is invalid {{rejects[0]}}</p>
    <p ng-show="rejects.length > 1">The following emails are invalid: {{rejects.join(', ')}}</p>
  </div>
  <div ng-show="inviteForm.list.$error.repeat">
      <p ng-show="repeats.length === 1">The following email is repeated:{{repeats[0]}}</p>
      <p ng-show="repeats.length > 1">The following emails are repeated:{{repeats.join(', ')}}</p>
  </div>
</form>

##Formatters If you set the model (with an array), each email will be formatted in the text area with a new line.
