What is an entrance mask?

Input mask is an expression that helps to define what type of contact is allowed in a given field on the template. The idea of ​​an input mask is to keep the data entering the data somewhat uniform and minimize the chances of incorrect data to be entered in the field. In some cases, the input field can be configured to allow automatic field input to save time and resources.

The input mask takes place during the computer programming process. The template fields are determined with specific control values. The values ​​make it impossible to enter data that are not compatible with values. For example, a field that contains an input mask that allows only letters automatically refuses to input numbers.

Another common input mask application has to do with automatic input conversion to an acceptable format. For example, an input mask may require the Date on the template to determine the format that structured as a date/month/year. Even if oneIvec enters the date in the field followed by the Moon/Date/Year format, the input system reads the data and automatically converts it to the correct form.

The automatic input is also very useful in many applications. In this scenario, the input mask is structured to start automatic filling of one or more fields based on the data entered in the previous field. For example, when someone enters the first and surnames into these fields, the input mask connects this information back with previously processed data and automatically enters this data into one or more following fields. As a result, it is only necessary to update several fields and save changes rather than re -enter any data to create a new file or document.

It is also not uncommon for the input mask to set a limit to the number of characters that can be entered in the field and requires a minimum number of characters. This can be particularly useful,When the file must contain data such as credit card numbers, phone numbers and similar information. This warranty alerts the individual data entry, if too many characters are entered, or if there are not enough characters to meet the minimum number. This helps minimize errors and prevents the need to fix the file later.
