How you can help. While you should always validate data on your servers, additional validation of data on the Web page itself has multiple benefits. In many ways, users are annoyed by forms. By validating form data while the user is filling it out, the user can know immediately if they've made any mistakes; this saves the time of waiting for an HTTP response and saves your server from dealing with bad form input. This article covers how to validate form data within your form's Web content. Using browser-supplied form validation One of the features of HTML5 is the ability to validate most user data without relying on scripts. This is done using validation attributes on form elements. When an element is invalid When an element is invalid, two things occur: The element matches the :invalid CSS pseudo-class; this will let you apply a specific style to invalid elements. Similarly, valid elements match the :valid pseudo-class. If the user tries to send the data, the browser will block the form and display an error message. Validation constraints on elements All e

It's not a good practise. –Jared May 1 '13 at 6:54 2 @Mahoor13 I have written it similar to that, but it never validates.

introduced several input types such as EMAIL, URL, RANGE, SEARCH, DATE, TIME, etc,. Most of the modern browsers have implemented them and are ready to be http://www.sagarganatra.com/2011/07/custom-validation-messages-for-html5.html used in a HTML document. Another exciting feature introduced in HTML5 is the form validation. Instead of writing JavaScript to validate users input, browsers can now validate it and show an http://www.the-art-of-web.com/html/html5-form-validation/ appropriate message if the validation fails. The validation message is shown in line with the field for which the validation has failed. The default error message is shown when the validation error message fails. In this post I'll explain how these error messages can be changed. Take an example of a form that has an input element with type="email" and a submit button:
After entering some text in the input field and on clicking the submit button, the default validation message is shown: The html5 form validation message style varies from browser to browser and the one shown in this picture is taken from Google's Chrome browser. As you can see, message "Please enter an email address." is shown when the user enters an invalid email address and clicks the submit button. This message is shown inline with the input field. To show a custom message, instead of default one the constraint validation API is used. Here the user can set the custom validation message using element.setCustomValidity(message): function check(input) { if(input.validity.typeMismatch){ input.setCustomValidity("Dude '" + input.value + "' is not a valid email. Enter something nice!!"); } else { input.setCustomValidity(""); } } From the code, the function check accepts a HTMLInputElement (input) as a parameter and checks for the validity of the input text entered against its type using input.validity.typeMismatch. It is set to true if the entered text doesn't match the specified input type. The input.setCustomValidity(message)is then used to set the validation message. Now whenever the validation fails the custom message will be shown: Similarly the custom validation message can be set in various conditions, such as required filed not entered -element.validity.valueMissing,form validation was until recently unthinkable. Sure there have been all kinds of whacky plug-ins over the years aimed at achieving this, but never a single standard that we could work towards. For a more detailed introduction to HTML5 form validation you can find some great articles linked under References below. In this article we intend to present only a number of simple examples to get you started, covering the basic form elements. Before you ask, and someone always does, these examples will currently work in the following browsers: Safari 5, Chrome 6, Opera 9, Firefox 4 Beta and the iPhone/iPad. Also each browser has a slightly different default behaviour. The 'required' attribute The simplest change you can make to your forms is to mark a text input field as 'required': Your Name: required> Your Name: This informs the (HTML5-aware) web browser that the field is to be considered mandatory. Different browsers may mark the input box in some way (Firefox 4 Beta adds a red box-shadow by default), display a warning (Opera) or even prevent the form from being submitted if this field has no value. Hopefully these behaviours will converge in future releases. For these examples we have created our own valid/invalid CSS formatting to override the browser default. More on that later. That's why you may see something like the following: Before you type anything into the box a red marker is shown. As soon as a single character has been entered this changes to a green marker to indicate that the input is 'valid'. Using CSS you can place markers inside or alongside the input box, or simply use background colours and borders as some browsers do by default. The required attribute can also apply to checkboxes which we've covered separately. New text INPUT types This is where HTML5 really gets interesting and more useful. Along with the text input type, there are now a host of other options, including email, url, number, tel, date and many others. On the iPhone/iPad the different input types are associated with different keyboards, making it easier for people to complete your online forms. In other web browsers they can be used in combination with the required attribute to limit or give advice on allowable input values. INPUT type="email" By changing the input type
