Today i got situation to validate text field containing comma separated numbers. I know how to validate numbers alone. But don’t know how to validate numbers with comma separated and each number should be 8 digits.
For example, 1234678,54872659,84567892,....
I searched google but didn’t find it and finally i got solution from my friend…
Here is the regular expression to do this trick,
/^(?:\s*\d{8}\s*(?:,|$))+$/
Usage:
<script language="javascript">
var pattern = /^(?:\s*\d{8}\s*(?:,|$))+$/;
var testvalue = document.getElementById('checkNumber').value;
if(pattern.test(testvalue)){
alert("Correct");
} else {
alert("Wrong");
}
</script>
More explanations on this regular expression, please check here
Hope this will be useful to you all.
