Javascript Regex：验证电话号码

Question

I want to validate a 11 digit phone number that must start with 09 (ie 09123456789) using javascript for client side check.

this is my code:

function validatePhone(number) {
    var re = /^09[0-9]{9}$/;
    return re.test(number);
}

It worked correctly as far as I know at first but now it return invalid for any number I use. Does anyone know what is wrong with my code? By the way as I'm using jQuery, if there is a better way with jquery that would be much better.

Answer 1

I am assuming you are sending an integer in the argument, pass it as a string

function validatePhone(number) {
    var re = /^09[0-9]{9}$/;
    return re.test(number);
}

​alert(validatePhone('09123456789'));​​​
// returns true    
alert(validatePhone(09123456789));    
// returns false    ​
