AngularJS Form details and sample code, angularjs sample code

AngularJS provides rich forms and verification. We can use ng-click to handle AngularJS click button events, and then use the $ dirty and $ invalid flag for verification. Use the novalidate form declaration to prohibit any browser-specific verification. Form Controls use a large number of corner activities. Let's take a quick look at the event first.

Event

AngularJS provides multiple events that can be associated with HTML controls. For example, ng-click is usually associated with a button. The following are events supported by AngularJS.

Ng-click

Ng-dbl-click

Ng-mousedown

Ng-mouseup

Ng-mouseenter

Ng-mouseleave

Ng-mousemove

Ng-mouseover

Ng-keydown

Ng-keyup

Ng-keypress

Ng-change

Ng-click

Use the command to click a button to reset the data in the form.

<input name="firstname" type="text" ng-model="firstName" required><input name="lastname" type="text" ng-model="lastName" required><input name="email" type="email" ng-model="email" required><button ng-click="reset()">Reset</button><script>  function studentController($scope) {    $scope.reset = function(){     $scope.firstName = "Mahesh";     $scope.lastName = "Parashar";     $scope.email = "MaheshParashar@yiibai.com"; }    $scope.reset();}</script>

Verify data

You can use the following trace error.

$ Dirty-the specified value has been changed.

$ Invalid-the status of this value is invalid.

$ Error-indicates the exact error.

Example

The following example shows all the preceding commands.
