I am trying to remove special characters from a given text.
I've tried to replace it with:
var stringToReplace = 'ab風cd 👰� abc 123 € AAA';
var newText = stringToReplace.replace(/[^\d.-]/g, '');
but it's not working. I want that the newText will be:
newText = 'ab cd abc 123 AAA'
I've tried some regex but none of them seem to work. the real problem is with '風' (those kind of characters). any suggestion? Thanks!
Just use.
stringToReplace.replace(/\W/g, ' ');
Output
"ab cd abc 123 AAA"
You could try the below,
> 'ab風cd 👰� abc 123 € AAA'.replace(/[^\dA-Za-z]/g, " ")
'ab cd abc 123 AAA'
[^\\dA-Za-z]
negated character class which matches any character but not of digits or alphabets.
OR
> 'ab風cd 👰� abc 123 € AAA'.replace(/[^\dA-Za-z\s]/g, "")
'abcd abc 123 AAA'
> 'ab風cd 👰� abc 123 € AAA'.replace(/[^\dA-Za-z\s]/g, " ")
'ab cd abc 123 AAA'
您的正则表达式不好,应该是:
var newText = stringToReplace.replace(/[^\da-z]/ig, ' ');
You could use /\\W/g
as your regex
\\W - The opposite of \\w. Matches any non-alphanumeric character.
For example:
var string = 'ab風cd 👰� abc 123 € AAA';
string = string.replace(/\W/g, ' ')
alert(string); // ab cd abc 123 AAA
