If the keyword isn't present in the text, the returned value is -1. The formulas we use here are indexOf('Input - Email'.text,".") and indexOf('Input - indexOf(): Find the starting position of a keyword in a text. The way to validate e-mail in ProtoPie is to check if the input text includes both "." and need 2 conditions for each trigger. Otherwise, an error message will show up. In the above case, the input needs to be an e-mail address. The following use cases will show you how to reuse this structure for different validation cases. To make different types of validation, we can only change the conditions under each trigger. In each trigger, a Condition is used to check if the text meets the requirement. A Detect is used to check/validate when the text meets the requirement so that the error messages disappear.A Focus(Focus out) is used to trigger an error message when the text doesn't meet the requirement.Generally, the method to validate the text entered into a text field in ProtoPie follows a similar structure with two main triggers: Focus and Detect. Let's start off with the general structure for text validation on input fields How to specify characters inside an input field.How to check the length of text or numerical characters of an input.How to check if the value of an input is wrong or correct.The general structure for creating text fields with input validation.We'll be using both triggers in this lesson. The Input feature allows you to type into text fields while the Detect feature checks what you have typed into the input field.īy combining these two triggers effectively in ProtoPie, you should be able to start creating your form fields with validation. ProtoPie makes creating these types of forms easy because it has two main triggers - Input and Detect that can perfectly imitate the behavior of a form field with validation. This means that the form has checked the input and detected that it's not correct. For example, when you type in the wrong email format in an email field on many websites, you'll get a message telling you that the email format you used is incorrect. This feature is used not only to guide users it also helps to verify that what the user has typed into the form field. Input validation is a common feature in modern-day apps and web applications. Wondering how to create text fields in your prototype that can check if what the user entered was correct? We have a really simple tutorial to help you with that.īefore we get started, you'll need to know what input validation is and how it works. Starting Pie File Completed Pie File Introduction
