This example uses the Java Script XMLHttp Request object and PHP server-side scripting to check that the Email address entered is valid (at least that it matches a particular regular expression) and that the Age lies between 16 and 100.

As the form is completed, the values are passed immediately to the server as POST variables, the server calculates a result, passing back an XML file which is then parsed to trigger various actions on the page as you will see.

This means that if the first Name field is changed and if the value is invalid as per the Angular validation directive e.g. separate error message for maxlength, required, pattern etc.

To implement it, we need to define separate The Mobile numbers can accept only 12 digits (includes country code).

For an Age input value of 12 the validation script returns the following XML document: s of elements in the HTML document.

The target value is also used to work out the id of the relevant checkbox and the DIV that will display feedback.

My feeling is that this article already describes how to generate the XMLHttp Request (Ajax) request, passing GET or POST variables to a server-side script using our Java Script class, and the related article referred to above provides a complementary PHP class for generating XML responses, so really all that's left is basic programming to process the incoming variables and generate the relevant XML response.

For those having trouble getting started, here's a walk-through: Hopefully that solves the problems some people have had implementing the code.

ng-class is the Angular directive used to apply class on the elements based upon the evaluated expression.

The expression ", checks the validation on first Name using $invalid and $dirty. Since we have several validation checks on element, we need to display corresponding error messages e.g.

The target value is also used to work out the id of the relevant checkbox and the DIV that will display feedback.
