On the past week, I tried to create a component text input that accept only number or characters that belong to numbers.
The limitation on text input for amount entering was mentioned by Ms. Peter the previous week. Users occasionally misread the characters and digits in the quantity input area.
The issue here is the time wasted on that procedure, not the fact that it will undoubtedly throw an error after publishing the request.
In order to retain the text just including numeric letters, we use regex to filter the input and delete everything that does not belong to numbers. Everything is now fine after creating the component and using regex, but we discovered another issue with the user interface, in which characters that don’t belong to numbers appear on changing text and then are removed. We need to find a solution where the regex function is called back before on changing text, but we haven’t yet defined that issue. I tried some suggestions, like onPressKey, but I still couldn’t figure out how to use it in my situation.
