Fields validation RegEx onChange client script

[Mrman]

Hi All,

I have requirement to validate the number entered in a field . For this I created Onchange client script and below RegEx is not working .It is not accepting the number even I give in below format . 

Please guide. 

Number format should be - 123-45-6789

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }


    var pattern =  /^([0-9]{3})+([-]{1})+((0-9)]{2})+([-]{1})+([0-9]{4})$/;  

     

    if (!pattern.test(newValue)) {
		g_form.clearValue('u_social_security_usa');
        g_form.showFieldMsg('u_social_security_usa', 'Enter a valid SSN ', 'error', true);
        
    } 
    //Type appropriate comment here, and begin script below

}

Hi

Your RegEx isn't doing quite what you're expecting it to. 

Try with this: 

/^\d{3}-\d{2}-\d{4}$/

Thanks @Mike Reading this worked . 

Could you please let me what was the mistake in my original RegEx .

Does \d indicate a digit ?

Hi @ramamr it was because you'd put a ( rather than a [ in the 2 digit section. 

Yes, \d means digit.

If you want a good visual reputation of what your regex is doing, you can paste it into https://regexr.com/ and it'll tell you down at the bottom what it's trying to validate against.
