Use js to replace all characters except numbers and commas

Use js to replace all characters except numbers and commas

Copy codeThe Code is as follows:
<Script language = "javascript">
Var str = "asdfk, asdf345345, 345345 ";
// Replace all characters except numbers and commas.
Str = str. replace (/[^ 0-9,] */g ,"");
// Remove the first comma
If (str. substr (0, 1) = ',') str = str. substr (1 );
// Remove the second comma
Var reg =/, $/gi;
Str = str. replace (reg ,"");
Alert (str );
</Script>

Result:

Copy codeThe Code is as follows:
345345, 345345
