Input masking is helpful while dealing with data like cards, phone numbers, zip codes, dates and more. Input masking is a way of restricting data entered by the users into form fields by enforcing a predefined format. For this purpose, we can use jQuery input mask plugin which is very lightweight and is easy to implement. This plugin helps in fetching the data from the server without any mess and after the user receives it, the data is automatically masked by the plugin while entering into form fields.
For all the three fields, formats are defined with certain patterns. In this example, placeholders are used to show the masks. Let us look at another similar example for jQuery input masking.
JQUERY INSTALL UNPKG CODE
ZIP Code has the format defined as X1X 1X1.When the input data is entered, the input box field will take the data in the predefined format automatically. In the given example, we are trying to specify certain formats for input fields, ZIP Code, ContactNumber and Policy Number using mask() feature. From the shown below output, we see that a format is defined for each of the three fields. Here is another similar example to understand the implementation of input masking. You can also find SweetAlert on unpkg and jsDelivr and use the global swal variable. In the screenshots, we can see that there is a predefined format available for all the three input fields which helps the user to easily enter fixed-length input. Installation Getting started Advanced examples Using with libraries.In this example, we have implemented masks for text input fields which accept a Card number, a Date and Contact.
These are those masks that can change during the input and can be defined using )
