Validating in c
If you do not return false then the message will be displayed to the user that all fields are required but the form will be post back and it gives you the second page directly. The condition that checks both text boxes for word are as in the following: In the preceding condition, first we ensure that the email id is not blank then we match the email id entered into the text box to the Regular Expression that is saved in the email Exp variable.
In this article we will learn about client-side validation that is done using Java Script. In the preceding syntax function is the keyword provided by the Java Script to declare a function and the Vildate Data() is the function name, now write the code inside the function as in the following.Net control's values in variables so it cannot be repeated again and again in our function the email Exp variable holds the pattern of the email id in the form of a regular expression.Now add the condition to ensure that all controls have a value, if the values are not entered in the form control then it will show a message.Net pages, User and User along with the User Java Script file.In the User page the user enters the form details and then only after validating the details the page is redirected to the User page.This is a form of "artifact or specification validation".
Building the product right implies the use of the Requirements Specification as input for the next phase of the development process, the design process, the output of which is the Design Specification.
Use the following code in the create button: In the code above, only after validating the form data, the page is redirected to the User page. Net web application and click on the Create button without inserting any data in the form, then it will show the following alert message.
In the preceding screen you clearly see that even I have wriiten the code on the create button to redirect to the next page but it will not be redirected because the form data is blank and it does not satisfy our validation condition that we set.
In software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and that it fulfills its intended purpose.
It may also be referred to as software quality control.
" On the other hand, software validation is: "Was X what we should have built? " Building the right product implies creating a Requirements Specification that contains the needs and goals of the stakeholders of the software product.
