JS: regex for numbers and spaces?

I'm using happyJS and use the regex underneath for phone validation

phone: function (val) {
        return /^(?:[0-9]+$)/.test(val);
    }

However this ONLY allows numbers. I want the user to be able to enter spaces as well like

238 238 45383

Any idea why return /^(?:[0-9 ]+$)/.test(val); is not doing the trick?

You can try the below regex for checking numbers and spaces.

function isTextAndNumberSpaceOnly(text) {
    var regex = /^[0-9 ]+$/;
    if (regex.test(text)) {
        return true;
    } else {
        return false;
    }
}

Try

/^[\d ]*$/.test("238 238 45383")


console.log(/^[\d ]*$/.test("238 238 45383"));

Personally I use this code and it works properly:

function validateMobile(mob) 
{ 
     var re = /^09[0-9]{9}$/
     if(mob.match(re))
         return true;
     else
        return false; 
}

Try

phone: function (val) {
    return /^(\s*[0-9]+\s*)+$/.test(val);
}

At least one number must be present for the above to succeed but please have a look at the regex example here

This is my suggested solution:

/^(?=.*\d)[\d ]+$/.test(val)

The (?=.*\d) asserts that there is at least one digit in the input. Otherwise, an input with only blank spaces can match.

Note that this doesn't put any constraint on the number of digits (only makes sure there are at least 1 digit), or where the space should appear in the input.
