I am trying to get a regex to check for only numbers and commas so for example
This will go through
1 0,3,4 1,3 1,3,15,12 This will not go through
abc 1,,3,,4 1,3, ,1,1 My current regex is
/[0-9]*[,][0-9]*/ it doesnt seem to work as what i wanted Can i get some help thanks
1,22 is a correct matchUse this Regex ^([0-9]+,)*[0-9]+$
var re = new RegExp('^([0-9]+,)*[0-9]+$'); function check(){ var str=$('#hi').val(); console.log(str); if(str.match(re)) $('#result').html("Correct"); else $('#result').html("InCorrect"); }<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="hi"> <button onclick="check()">Check</button> <p id="result"></p>
Regex: ^\d+(?:,\d+)*$
var array = ['1', '0,3,4', 'abc', '1,,3,,4', '1,3,', ',1,1']; for (var i of array) { console.log(i + ' => ' + /^\d+(?:,\d+)*$/g.test(i)) }This isn't Regex, but here is a way to do it:
// Your test input values (which I will assume are strings for this code): /* * 1 * 0,3,4 * 1,3 * 1,3,15,12 */ const str = '1,3,15,12'; const isValid = str.split(',') .map((val) => !isNaN(parseInt(val))) .reduce((currentVal, nextVal) => currentVal && nextVal, true); console.log(isValid);Your current regex: /[0-9]*[,][0-9]*/ will match ,
1,1
,6
4953,5433
5930,
etc.
Assuming you want to match a comma-separated list of numbers (each with any number of digits), You would need: /\d+(,\d+)*/ where \d is shorthand for [0-9]:
/[0-9]+(,[0-9]+)*/
