生成字符串以在Javascript上使用正则表达式

Question

I'm making a faker plugin ( jQuery-Faker ) in jQuery which generates fake data for fill in the form corresponding to their field name. So I want to generate phone number using regular expression /\\(?([0-9]{3})\\)?([ .-]?)([0-9]{3})\\2([0-9]{4})/ So is there any way to do this?

Answer 1

You might want to look at the string from regex family of libraries.

Here is the one for javascript

As seen in the README you can do

var RandExp = require('randexp');
var phoneGenerator = new RandExp(/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/);
phoneGenerator.gen(); // =>

Try utilizing String.prototype.replace()

 var n = "01234567890".split("") , ph = "nnn-nnn-nnnn".replace(/n/g, function() { var i = Math.floor(Math.random() * n.length); return n.slice(i, i + 1)[0] }); document.write(ph);
