I need to replace all digits.
My function only replaces the first digit.
var s = "04.07.2012";
alert(s.replace(new RegExp("[0-9]"), "X")); // returns "X4.07.2012"
// should be XX.XX.XXXX"

You need to add the "global" flag to your regex:
s.replace(new RegExp("[0-9]", "g"), "X")
or, perhaps prettier, using the built-in literal regexp syntax:
.replace(/[0-9]/g, "X")
Use
s.replace(/\d/g, "X")
which will replace all occurrences. The g
means global match and thus will not stop matching after the first occurrence.
Or to stay with your RegExp
constructor:
s.replace(new RegExp("\\d", "g"), "X")
The /g
modifier is used to perform a global match (find all matches rather than stopping after the first)
You can use \d
for digit, as it is shorter than [0-9]
.
JavaScript:
var s = "04.07.2012";
echo(s.replace(/\d/g, "X"));
Output:
XX.XX.XXXX
find the numbers and then replaced with strings which specified. It is achieved by two methods
Using a regular expression literal
Using keyword RegExp object
Using a regular expression literal:
<script type="text/javascript">
var string = "my contact number is 9545554545. my age is 27.";
alert(string.replace(/\d+/g, "XXX"));
</script>
**Output:**my contact number is XXX. my age is XXX.

You forgot to add the global operator. Use this:
var s = "04.07.2012";_x000D_
alert(s.replace(new RegExp("[0-9]","g"), "X"));
_x000D_
