<!-- Clean, right ? -->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>

angular.module('yourApp', ['validation'])
.config(['$validationProvider', function ($validationProvider) {

validationProvider

.setDefaultMsg({

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>
<!-- Clean Reset (angular validation 1.2.0) -->
<button validation-reset="Form"></button>
</form> // ... checkValid
$scope.form.checkValid = validationProvider.checkValid;
// ... reset
$scope.form.reset = function (form) {
validationProvider.reset(form);
};
// ... angular validation 1.2.0 reset
$scope.form.reset = function () {
// Don't need include validationProvider.reset();
// Focus on your ng-click action
};Set the valid/invalid message style CSS
<span><p class="validation-valid">Your valid message here<p></span>
<span><p class="validation-invalid">Your invalid message here<p></span>.validation-valid {
<!-- valid style -->
}
.validation-invalid {
<!-- invalid style -->
}Custom the valid/invalid message style HTML in .config(),
setErrorHTML(func) setSuccessHTML(func), input should be a function and given parameter which is the valid/invalid message declared
in getDefaultMsg(),and finally return the HTML code
// your angular
.config(['$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)
}]);- Required

- Number
Anyone can give a PR for this angular-validation for more built-in validation
To integrate this package with Bootstrap you should do the following.
Add the following LESS to your project
.ng-invalid.ng-dirty{
.has-error .form-control;
}
label.has-error.control-label {
.has-error .control-label;
}Change the Error HTML to something like:
$validationProvider.setErrorHTML(function (msg) {
return "<label class=\"control-label has-error\">" + msg + "</label>";
});You can add the bootstrap class .has-success in a similar fashion.
See release
###Can I validate the form when init ? #10###
<form name="Form">
<input type="text" name="number" ng-model="form.number" validator="number"/>
<button id="button1111" ng-click="form.submit(Form)">Show</button>
</form>$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.
###When using checkValid() manually #19###
Before using checkValid(), you have to execute submit first to get the latest result.
