Validating password using javascript


He has experience in Java, Java Script, Golang and a variety of frameworks such as Angular, Native Script, and Apache Cordova.

If you're working with arrays of checkboxes to submit data to a server-side script then you might already have some grey hairs from trying to figure out how to validate the input using Java Script.

The problem is that, to have the data submitted in a 'nice' format to the server, the function returns an array containing all the selected checkbox values. Again, we can make the code a lot simpler in supporting browsers: suffix tells a server side script such as PHP to accept multiple values with that name into an array.

To show the password strength to the user, we’re going to use a rectangle that contains a color.

We’ll say that a red rectangle holds a weak password, orange medium, and green a strong password.

Instead of parsing through the string using tokens or some other nonsense we managed to validate our string using a single line of code.

Finally we need a way to track input on the input field.The value of a text input box (or a textarea or password input) is available using the syntax that tells you which option has been selected.
