Fixing Firefox Bug: How to Eliminate Non-Numeric Characters from "Number" Input Fields

Completing this task seems straightforward. I need to eliminate any non-numeric characters from an input field specified as type "number" in Firefox when a key is pressed.

The code snippet provided:

$("#field").on("keyup", function() {
 regex = /[\\D]+/;
 $(this).val( $(this).val().replace(regex, '') );
});

However, the issue arises where entering a non-numeric character causes the entire content of the field to be replaced by an empty string.

For instance:

234d = emptied > should become 234

Solution (discussed here due to question closure):

After investigating further, it appears that the problem lies with the field type. When using an input field of type "number" and introducing non-numeric characters, Firefox displays them but does not store them in the input object. Switching to a text input resolves the issue. It appears to be specific to Firefox.

I believe this question stands out as unique because it pertains to a Firefox-related complication with input fields of type "number".

Answer №1

let number = '678e'.replace(/[^0-9]/g, '');

console.log(number);

Answer №2

let message = '234d';

Give this code a shot:

message = message.replace(/\D/g,'');
