Question

I’m making a contact form which will be submitted with jQuery and I’m stuck on one simple validation.

I need to validate a field, which has to have at least x integers.

How can I do this?

p.s: please don’t suggest validation plugin.

Thanks,

edit: This is what I’ve tried, but it’s wrong I guess.

var numbercheck = /^(\w\d{7,14})?$/;

this is jsdiffle:

Use regex providing the range of numbers you can afford in your field

like \d{5,10} // Here 5 -10 is the range of numbers

function testContact(contact){
 contact = contact.replace(/[a-z]*/g,"");
 return (contact == contact.match(/\d{5,10}/))?true:false;
}
