I know this is an old post, but I thought I would share my solution to help others.

This function will work if you want to valid 10 digits phone number "US number"

function getValidNumber(value)
{
    value = $.trim(value).replace(/\D/g, '');

    if (value.substring(0, 1) == '1') {
        value = value.substring(1);
    }

    if (value.length == 10) {

        return value;
    }

    return false;
}

Here how to use this method

var num = getValidNumber('(123) 456-7890');
if(num !== false){
     alert('The valid number is: ' + num);
} else {
     alert('The number you passed is not a valid US phone number');
}
