jqueryHow do I use jQuery MaskedInput to format user input?

jQuery MaskedInput is a plugin that allows you to add a mask to an input field to format the user’s input. It is a very useful tool for making sure that user input is in the correct format.

To use jQuery MaskedInput, you first need to include the plugin's JavaScript file.

<script src="jquery.maskedinput.js"></script>

Then you can call the mask function on the input field to define the mask. The mask is a string that defines which characters are accepted and where they should appear.

$("#inputField").mask("(999) 999-9999");

The mask in the example above defines that the input should consist of three digits, followed by a space, followed by three digits, followed by a dash, followed by four digits.

You can also define custom placeholder characters for the mask.

$("#inputField").mask("(999) 999-9999", {placeholder: "X"});

In the example above, the placeholder character is set to X. This means that the input field will be pre-filled with Xs, and the user will have to replace them with the correct digits.
