AngularJS and AngularUI: mask or format a phone number when binding

Question

I am using AngularUI to format or "masking" a phone number input, and it works fine with a ng-model:

<input ng-model="emer.phone" ui-mask="{{'(999) 999-9999'}}" type="text"/>

Question: But now how can I apply the same mask in the same way using ng-bind, I have something like this:

<td>{{emer.phone}}</td>

My problem: The ng-model and ng-bind are in two different files in different locations, therefor the use of "$viewValue" is not an option for me

Any idea?

some documentation about AngularUI mask: http://angular-ui.github.io/ui-utils/

Thanks!

Answer 1

You should use ui-mask="(999) 999-9999" instead of ui-mask="{{'(999) 999-9999'}}".

The latter tries to bind to a model with '(999) 999-9999' on it.

Instead of making your own masking or perhaps building your own directive you can make use of existing solutions.

Take tel.js for example. It is an input[tel] directive that formats and validates international phone numbers for you.

You can install it from bower like this:

bower install teljs --save

Then:

1. Link the two script files found in the 'src' folder: tel.js and metadatalite.js.

   <script src="bower_components/teljs/src/tel.js"></script>
   <script src="bower_components/teljs/src/metadatalite.js"></script>
   

2. Load the tel.js module.

   angular.module('<your module>', ['teljs']);
   

You can try out tel.js here:

Remark: I am the developer of tel.js.

SO far I couldn't find a simple solution using AngularUI mask, so I had to create a filter. I follow this: Format telephone and credit card numbers in AngularJS

And here is the jsfiddle: http://jsfiddle.net/jorgecas99/S7aSj/

angular.module('ng').filter('tel', function () {
    return function (tel) {
        if (!tel) { return ''; }

        var value = tel.toString().trim().replace(/^\+/, '');
        ...

Cheers!

I can see in the ui-mask demo, they cheat a bit and use the $viewValue from ngModelController.

So, you could try the same thing.

First, you must add a name to your input field and be wrapped in a form (with a name):

<form name="demo">
    <input name="emerPhone" ng-model="emer.phone" ui-mask="{{'(999) 999-9999'}}" type="text"/>
    <td>{{demo.emerPhone.$viewValue}}</td>
</form>

As you can see from the above example, the display code becomes:

<td>{{demo.emerPhone.$viewValue}}</td>

It would have been better if they would have provided a filter as well, though.

Also, I can see that in the demo for ui-mask, they show and hide based on the length of the $viewValue:

<div ng-show="demo.masked.$viewValue.length">NgModelController.$viewValue: <code>{{ demo.masked.$viewValue
              }}</code></div>
            <div ng-hide="demo.masked.$viewValue.length">NgModelController.$viewValue: <code>undefined</code></div>

Hope this helps.
