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. Can you gimme a hint ? jsfiddle.net/2USxy –Sliq May 31 '13 at 23:36 1 There's also a custom Firefox property you can add which works well: x-moz-errormessage="Please enter only numbers" –coliff Sep 18 '13 at 13:40 2 better to use "onkeyup" instead of "onchange" to see effectively if the input is valid or not. –Jam Ville Jun 2 '14 at 2:38 1 replacing oninput with onchange fixed my problem on firefox when textFiled is focused –h0mayun Dec 14 '14 at 9:56 | show 2 m

How To Show Error Message In Html5
them and are ready to be used in a HTML document. custom error message in excel Another exciting feature introduced in HTML5 is the form validation. Instead of writing JavaScript to validate users custom error message rails input, browsers can now validate it and show an appropriate message if the validation fails. The validation message is shown in line with the field for which the http://stackoverflow.com/questions/10361460/how-can-i-change-or-remove-html5-form-validation-default-error-messages validation has failed. The default error message is shown when the validation 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 http://www.sagarganatra.com/2011/07/custom-validation-messages-for-html5.html text in the input field and on clicking the submit button, the default validation message is shown: The 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.setCustomVeasy. All we have to do is use attributes like required, maxlength, pattern, step, etc. and/or the correct form type like email, phone, number, etc. and then once the user submits http://codetheory.in/custom-validation-messages-for-html5-form-constraints/ the form, the browser prompts invalid messages if the form is not entirely valid. Although it might not really be a requirement but from a coolness perspective I thought I'll share the fact that the error messages can be customized. Here's a small demo first to prove my point: See the Pen html5 form validation custom messages by Rishabh (@rishabhp) on CodePen. The error message that error message you see when submitting the form without writing anything in the email field is not the browser default. Playing with the error messages is done with the setCustomValidity() method of the constraint validation API. checkValidity(), validationMessage and setCustomValidity() Let's talk about the checkValidity() API call first which can basically be triggered on any form element (or even the form itself) which is a candidate for form validation custom error message and if the data is invalid, an invalid event will be triggered on the element. The method itself returns false when the data is invalid, otherwise it'll do nothing and just return true Every form control will have a property called validationMessage which will contain the message (localized) to show to the user when the field fails to validate against the constraints (like required for instance). If the field contains valid data then this property will be set to an empty string ''. Setting the validationMessage directly won't work, hence the setCustomValidity() API method has to be called to override validationMessage and this is the trick to customize your error messages. If you noticed I used it initially to set a custom error message: email.setCustomValidity('Need your email bro!'); Next, on the input event (fired as the user writes something in the input/textarea fields), if the value of the field appears to be an empty string then the custom error message for a required field is set which is shown in the browser's default validation bubble. Otherwise if some value is set, we pass an empty string to setCustomValidity(). Although an empty string means valid data, the browser
