8 位电话号码的正则表达式（新加坡号码长度）

Question

I'm trying to validate my phone address text field. Can anyone provide me a simple regex to either validate for numeric digits only or a specific 8 digit regex?

Much thanks!

$('#phone').on('input', function() {
var input = $( this );
var regex = /* regex needed here */
var is_phone = regex.test(input.val());
if (is_phone){input.removeClass("invalid").addClass("valid");}
else {input.removeClass("valid").addClass("invalid");}
});

It will allow 0-9 numbers and only 8 digits. Try this:

var regex = '/^[0-9]{1,8}$/'; // if you want min 1 and max 8 numbers

var regex = '/^[0-9]{8}$/'; // if you want exact 8 numbers
