mw-error-messages

mw-error-messages is an AngularJS module that wrap the ngMessage into a easy to use directive for error validation. It has several features like an icon in the input field or to show that a field is valid and invalid.

Requirements (tested in)

• Angular (v1.6.6)
• NgMessages (v1.6.6)
• Bootstrap (v3.3.7) used as default grid system
• (Optional) FontAwsome (4.3.0) or another font if you want to use icons
• (Optional) ui-bootstrap (2.5.0)

Install

You can install this package either with npm or with bower.

npm

npm install mw-error-messages --save

bower

bower install mw-error-messages

Usage

Once the script is included in your html file, simply include the module in your app:

angular.module('myApp', ['ngMessages', 'mw-error-message']);

And use the included 'mwErrorMessage' directive thusly:

<div mw-error-message="CTRLSYSTEM_">
    <input title="" type="text" name="test" ng-model="model.test" class="form-control" required/>
</div>

The content of mw-error-message is used as the label or if you use a translation directive its used as a prefix combined with the name of the input field. In this example the marker would be 'CTRLSYSTEM_TEST'.

If you use the required attribute, a '*' will be placed behind the label to mark this field as required. This also works with ng-required.

icon, success and addtional_help_block can be changed in the html like:

<div mw-error-message="CTRLSYSTEM_" mw-error-message-options="mwOptions">
    <input title="" type="text" name="test" ng-model="model.test" required/>
</div>

$scope.mwOptions = {
    icon: true,
    tooltip: true,
    success: true,
    addHelp: '<span>Additional Help block</span>'
};

If you want to use other Font icons just override this:

.has-success .wm_error_message_icon:after{
    content: "\f00c";
}
.has-error .wm_error_message_icon:after{
    content: "\f00d";
}

If you want to use more messages or change the content of the default message:

// override default message
mwConfig.messages['required'] = 'This field is required';
//add a new message
mwConfig.messages['birthday'] = 'You need to be 18 years old.';
