R&D: Restrict Text Input JavaScript 2012/07/07
Important!
Dear visitors,
This blog and the Tigarus.com network will be changing our website software in May (2024). There will be some down time and there will be a change to the webpage addresses.
We will also be removing the Anime blogs. The Rocksmith Songs website will be unavailable of a few weeks or months while I move the database to the new software.
At the moment we are running on Wordpress, the new software is an in-house project which is 57 times faster. It will also provide more freedom for development.
Thank you for understanding.
I have been working on a Web App that requires the text input field to be restricted to only number inputs without restricting regular user interface functionality such as copy and paste.
For a long time I thought restricting an input field was as simple as Adobe Flash’s Action Scripting, but as it turns out JavaScript has no such method.
As a result I have struggled with keydown and keypress differentials, restricting copy and paste to just digits and limiting the number of input-able periods “decimals”.
Conclusion, although I have over come many difficulties, restricting an input field is no easy task and I don’t think there will ever be an easy solution made by me.
