Form validation is natively supported by the browser, but sometimes different browsers will handle things in a manner which makes relying on it a bit tricky. Let’s look at the HTML first: is a temporary URL that would point to something real on a server someplace (where you have backup server-side validation of course).Even when validation is supported perfectly, there may be times when custom validations are needed and a more manual, Vue-based solution may be more appropriate. Beneath that there is a paragraph that shows or hides itself based on an error state.
If you're concerned about security you should have some policy on what constitutes a valid password.by making use of String operations and checking the various requirements for a valid Email Address using Java Script.Button is clicked, the Email Address in the Text Box will be validated using Java Script without using Regular Expression (Regex) and if the Email Address is invalid, the error message will be displayed next to the Text Box.You can play with this here: See the Pen form validation 3 by Raymond Camden (@cfjedimaster) on Code Pen.In my final example, we built something that makes use of Ajax to validate at the server.Because the input type obscures the text typed, you should let the user confirm that they haven't made a mistake.
The simplest way to do this is to have the password entered twice, and then check that they are identical.
For the second example, the second text field (age) was switched to email which will be validated with a bit of custom logic.
The code is taken from the Stack Overflow question, How to validate email address in Java Script? This is an awesome question because it makes your most intense Facebook political/religious argument look like a slight disagreement over who makes the best beer. Here is the HTML, even though it’s really close to the first example. You can play with this example here: See the Pen form validation 2 by Raymond Camden (@cfjedimaster) on Code Pen. This tells Vue to cast the value to a number when you use it.
In some cases, such as on mobile devices, displaying the password may improve usability without compromising security.
After all it's only the browser display being obfuscated and not the data transfer.
Another method is to display what they've entered as part of a 'confirmation page'.
