Is there a way to transform the number 20,00 into 2000 using JavaScript? I am looking to eliminate the decimal point while retaining all digits intact.
Is there a way to transform the number 20,00 into 2000 using JavaScript? I am looking to eliminate the decimal point while retaining all digits intact.
Watch out, everyone! I'm a pro at using regular expressions!
var originalstring = '20,00';
var newstring = originalstring.replace(/,/g, '');
In simpler terms, use the replace() method to get rid of all occurrences of , and replace them with nothing. If you want to be more specific and only keep digits, you can use a character class like this:
var originalstring = '20,00';
var newstring = originalstring.replace(/[^0-9]/g, '');
This could come in handy because different languages have different decimal separators (for instance, in English (en_US), "two and a half" is written as "2.5", while in Czech (cs_CZ) it appears as "2,5"). Even though JavaScript always uses a decimal point for numbers, input from users may vary based on their locale settings (like how pressing the key next to 0 on some keyboards types a comma instead of a period). This can lead to confusion if your script expects a decimal comma but receives a decimal point instead.
Utilize the JavaScript method replace
"20,00".replace(/,/g,"")
Utilize Regular Expressions to your advantage:
"20,00".replace(/[^\D]/g, '');
By using this code, you can eliminate any non-digit characters.
Another solution without using regular expressions.
var updatedResult = "20,00".split(',').join('');
If the number is stored as a string, one way to convert it into an integer is by using
parseInt('20.00'.replace(/\./, ''))parseInt('20.00'.replace(/,/, ''))When dealing with strings that contain only one comma, you can simply use the replace method without even resorting to regex:
"50,99".replace(',', '');
// will result in 5099
