Using angular-validation

angular.module('yourApp', ['validation']);

Writing your Code

Add Valid Message (error, success) for validation required
required-error-message and required-success-message

<label>Required</label>
<input type="text"
       name="require"
       ng-model="form.required"
       validator="required"
       required-error-message="Required"
       required-success-message="Good Required"/>
       <!-- or you can try
       required-error-message="{{ RequiredMsg }}"
       -->

Add Valid Message (error, success) for validation email
email-error-message and email-success-message

<label>Email</label>
<input type="text"
       name="email"
       ng-model="form.email"
       validator="email"
       email-error-message="Error Email"
       email-success-message="Good Email"/>

Use Default Valid Message
you don't need to give valid message

<label>Number</label>
<input type="text" name="number" ng-model="form.number" validator="number"/>

Don't show the Valid Message no-validation-message="true"

<label>Number</label>
<input type="text" name="number" ng-model="form.number" validator="number" no-validation-message="true"/>
<!-- or {{ your.Scope.Name }} -->
<input type="text" name="number" ng-model="form.number" validator="number" no-validation-message="{{ noValidationMessage }}"/>

Add Valid Callback Function, invalid-callback & valid-callback

<label>Required (Invalid Callback alert)</label>
<input type="text" name="requiredCallback" ng-model="form.requiredCallback" validator="required" invalid-callback='error("Must be Required");'/>

Select the validation method watch blur submit submit-only, default as watch
validationProvider.validate(form).success(callback).error(callback) use callback to continue your submit

<label>Watch method</label>
<input type="text" name="number" ng-model="form.number" validator="number" valid-method="watch"/>
<input type="text" name="number" ng-model="form.number" validator="number"/>

<label>Blur method</label>
<input type="text" name="number" ng-model="form.number" validator="number" valid-method="blur"/>

<label>Submit method</label>
<form name="Form">
    <input type="text" name="number" ng-model="form.number" validator="number" valid-method="submit"/>
    <button ng-click="form.submit(Form)"></button>
</form>

<label>Submit Only method</label>
<form name="Form">
    <input type="text" name="number" ng-model="form.number" validator="number" valid-method="submit-only"/>
    <button ng-click="form.submit(Form)"></button>
</form>

<script>
    // ... validate method, it will check `checkValid(Form)`
    $scope.form = {
        submit: function (form) {
            $validationProvider.validate(form)
                .success(successCallback)
                .error(errorCallback);
        }
    };
    // ...
</script>

Setup a new Validation setExpression() setDefaultMsg() with RegExp or Function in config phase

<!-- View -->
<label>IP address (Custom setup the new validator - RegExp)</label>
<input type="text" name="ip" ng-model="form.ip" validator="ip"/>

<label>Huei (Custom setup the new validator - Function)</label>
<input type="text" name="huei" ng-model="form.huei" validator="huei"/>

// your module
angular.module('yourApp', ['validation'])
    .config(['$validationProvider', function ($validationProvider) {
        // Setup `ip` validation
        var expression = {
            ip: /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/
        };

        var validMsg = {
            ip: {
                error: 'This isn\'t ip address',
                success: 'It\'s ip'
            }
        };

        validationProvider.setExpression(expression); // set expression
        validationProvider.setDefaultMsg(validMsg); // set valid message

        // Setup `huei` validation
        validationProvider.setExpression({

            /**
            * @param value , user input
            * @returns {boolean} true iff valid
            */
            huei: function (value) {
                return value === 'Huei Tan';
                // or you can do
                return $q.all([obj]).then(function () {
                // ...
                    return true;
                })
            }
        });

        validationProvider.setDefaultMsg({
            huei: {
                error: 'This should be Huei Tan',
                success: 'Thanks!'
            }
        });
    }]);

Check form whether valid, return true if valid. checkValid()
Reset the specific Form. reset()

<form name="Form">
    ...
    <!-- Check the entire form valid from angular-validation `valid` -->
    <button ng-disabled="form.checkValid()"></button>
    <!-- or Check the specific form(Form) valid from angular `$valid` -->
    <button ng-disabled="form.checkValid(Form)"></button>
    <!-- Reset the specific Form -->
    <button ng-click="form.reset(Form)"></button>
</form>

    // ... checkValid
    $scope.form.checkValid = validationProvider.checkValid;
    // ... reset
    $scope.form.reset = function (form) {
        validationProvider.reset(form);
    };

Set the valid/invalid message style CSS

<span><p class="validation-valid">Your valid message here<p></span>
<span><p class="validation-invalid">Your invalid message here<p></span>

.validation-valid {
    <!-- valid style -->
}

.validation-invalid {
    <!-- invalid style -->
}

Custom the valid/invalid message style HTML in .config(),
setErrorHTML(func) setSuccessHTML(func), input should be a function and given parameter which is the valid/invalid message declared in getDefaultMsg(),and finally return the HTML code

// your angular
.config(['$validationProvider', function ($validationProvider) {
    $validationProvider.setErrorHTML(function (msg) {
        // remember to return your HTML
        // eg: return '<p class="invalid">' + msg + '</p>';
    });

    $validationProvider.setSuccessHTML(function (msg) {
        // eg: return '<p class="valid">' + msg + '</p>';
    });
}]);

disable/enable show success/error message
default: true
Easily disable success/error message

// your angular
.config(['$validationProvider', function ($validationProvider) {
    $validationProvider.showSuccessMessage = false; // or true(default)
    $validationProvider.showErrorMessage = false; // or true(default)
}]);

Built-in validation in angular-validation

• Required
• Url
• Email
• Number

Anyone can give a PR for this angular-validation for more built-in validation

Developer Adding a new validation

Clone the repo to your computer

git clone https://github.com/huei90/angular-validation.git

Install Grunt and Download dependencies

npm install -g grunt-cli
npm install

Before coding Boot the Environment

grunt dev

Start coding

open `provider.js`, looking for `var expression` and `var defaultMsg`
Adding a new expression and defaultMsg to extend it

IP validation As the example

// provider.js
var expression = {
    required: /.+/gi,
    ... // add new expression below
    ip: /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/
};

var defaultMsg = {
    required: {
        error: 'This should be Required!!',
        success: 'It\'s Required'
    },
    ... // add new valid message below
    ip: {
        error: 'This isn\'t ip',
        success: 'It\'s IP'
    }
};

Q & A

###Can I validate the form when init ? #10###

<form name="Form">
    <input type="text" name="number" ng-model="form.number" validator="number"/>
    <button id="button1111" ng-click="form.submit(Form)">Show</button>
</form>

$timeout(function () { // call $timeout to make sure the Form Constructor is generated
$validationProvider.validate($scope.Form); // $scope.Form is html form name `Form Constructor`
});

###What's the differentiate between validator-method submit and submit-only#4###

submit : when user click submit, then start watching using watch to validate
submit-only : when user click submit, doesn't validate through watch until submit button is clicked.
