I have a string in the form: "xMyS"
I want to extract x and y in using the Javascript Regex expressions.
For example, if the string is
10M225S
I need 10 and 225 from this.
Also, the string might not have either of x or y part. For example it can be just 225S or just 10M.
EDIT: I tried things like .match(), but don't know how to extract values in the mentioned format.
EDIT: The regex I tried so far is /(\w+)M(\w+)S/, but it seems to only work for 10M225S and not for 10M and 225S.

- 2 have you tried anything? where are you stuck? – Cruiser Commented Dec 14, 2016 at 14:16
- 2 What have you tried so far? Did you google "javascript regular expressions"? – slim Commented Dec 14, 2016 at 14:17
- Yes...I did google about it. Found about .match(), but can't seem to get it done. – dsaket Commented Dec 14, 2016 at 14:18
- [^A-Z] is the regular expression to match x and y – DanieleO Commented Dec 14, 2016 at 14:40

Reset to default 15You can do something like this:
var str = "10M255S"
var match = str.match(/^([0-9]*)M*([0-9]*)S*$/)
Then match[1] is 10 and match[2] is 255
If var str = "10M", then match[1] is 10 and if var str = "255S", then match[1] is 255
In any of the three cases, matches start from second element of the array match.
Hope this helps.
you can use .split() to split the strings:
var str = "10M225S"
var m = str.split("M")[0];
var s = str.split("M")[1].split("S")[0];
console.log("m >>> " + m);
console.log("s >>> " + s);no need for regular expressions in this case.
K-Gun's answer makes sense if the pattern never varies, however if 'M' and 'S' are simply placeholder examples for arbitrary text, then use the RegExp /\d+/g
<!DOCTYPE html>
<html>
<head>
<script>
function fn() {
var re = /\d+/g, // match digits, globally
str = '10M225S',
result = [],
temp;
// process successive matches
while ((temp = re.exec(str)) !== null)
result.push(temp[0]);
document.getElementById("result").innerText = result.toString();
}
</script>
</head>
<body onload="fn()">
<h1 id="result"></h1>
</body>
</html>
Here's a plunkr demonstrating the code.
The RegExp re will match runs of digits. This will work regardless of any non-digit characters, e.g. it would match "10ZXZZ225FOZ".
var str = "10M255S"
var result = str.match(/([0-9])/g)
var value = []
result.map(res => {
value += res
})
console.log(value)
