Number input in JavaScript being disrupted by stray commas

On my webpage, there are elements that users can control. One of these is a text input field for numbers. When users enter digits like 9000, everything functions correctly. However, if they use comma notation such as 9,000, JavaScript doesn't recognize this input as an integer.

Is there a way to remove the commas and convert the input to an integer? I attempted using parseInt(), but it didn't work with commas.

Answer №1

To remove all commas from a string, utilize a global regular expression:

var text = "1,234,567";
text = text.replace(/,/g, "");
parseInt(text, 10);

Answer №2

or perhaps improve upon

let value = "jdjsghd0182.99";
let number = parseFloat(value.replace(/[^0-9 | ^.]/g, ''));

Answer №3

To address the issue of unreliable user input, it's recommended to eliminate all non-numeric characters using the following approach:

<pre>
var userString = "9,Ljk876";
var numericOnly = parseInt(userString.replace(/[^0-9]/g, ''));
alert ("User Input:" + userString + ", Numeric Only:" + numericOnly);
</pre>

Answer №4

perhaps

 parseInt(valueWithoutCommas.replace(/\,/g,""))

let's discuss the limitation :

you may allow the user to input both 9000 & 9,000

validation can be done using REGEX.

on the server side - remove the commas and treat it as an integer.
